The RING-variant domain is a C4HC3 zinc-finger like motif found in a number of cellular and viral proteins; Some of these proteins have been shown both in vivo and in vitro to have ubiquitin E3 ligase activity. The RING-variant domain is reminiscent of both the RING and the PHD domains and may represent an evolutionary intermediate. To describe this domain the term PHD/LAP domain has been used in the past. Extended description: The RING-variant (RINGv) domain contains a C4HC3 zinc-finger-like motif similar to the PHD domain, while some of the spacing between the Cys/His residues follow a pattern somewhat closer to that found in the RING domain. The RINGv domain, similar to the RING, PHD and LIM domains, is thought to bind two zinc ions co-ordinated by the highly conserved Cys and His residues.

lantibiotic immunity ABC transporter permease (also called ABC-2 transporter permease) subunit; This family contains lantibiotic ABC transporter permease subunits which are highly hydrophobic, integral membrane proteins, and part of the bacitracin ABC transport system that confers resistance to the Gram-positive bacteria in which this system operates, particularly to type-A lantibiotics. Lantibiotics are small peptides, produced by Gram-positive bacteria, which are ribosomally-synthesized as pre-peptides and act by disrupting membrane integrity. Genes encoding the lantibiotic ABC transporter subunits are highly organized in operons containing all the genes required for maturation, transport, immunity, and synthesis. For example, in Lactococcus lactis, the lantibiotic nisin is active against other Gram-positive bacteria via various modes of actions; however, its self-protection against the pore-forming nisin is mediated by the ABC transporter composed of NisF, NisE and NisG subunits. This family includes the Lactococcus lactis NisG permease subunit that transports nisin to the surface and expels it from the membrane. This family also includes the lantibiotic ABC transporter permease subunits EpiE, MutE, MutG, and SlvE. Self-protection of the epidermin-producing strain Staphylococcus epidermidis Tu3298 against the pore-forming lantibiotic epidermin is mediated by an ABC transporter composed of the EpiF, EpiE, and EpiG proteins. In the mutacin I-producing strain Streptococcus mutans CH43, self-immunity against mutacin I is mediated by proteins MutF, MutE, and MutG, while in salivaricin D-producing strain Streptococcus salivarius 5M6c, mediation is via ABC transporter proteins SlvF, SlvE, and SlvG.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING finger proteins MARCH2, MARCH3, and similar proteins; MARCH2 and MARCH3 contain a C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, in the N-terminal cytoplasmic region, two transmembrane domains in the middle region, and a PDZ-binding motif at the C-terminus. MARCH2 is a Golgi-localized, membrane-associated E3 ubiquitin-protein ligase that is involved in endosomal trafficking through the binding of syntaxin 6 (STX6). It is involved in the cystic fibrosis transmembrane conductance regulator (CFTR)-associated ligand (CAL)-mediated ubiquitination and lysosomal degradation of mature CFTR through the association with adaptor proteins CAL and STX6. It also reduces the surface expression of CD86 and the transferrin receptor TFRC and regulates cell surface carvedilol-bound beta2-adrenergic receptor (beta2ARs) expression. Moreover, MARCH2 interacts with and ubiquitinates PDZ domains polarity determining scaffold protein DLG1 through its PDZ-binding motif, suggesting it may function as a molecular bridge with ubiquitin ligase activity connecting endocytic tumor suppressor proteins such as syntaxins to DLG1. MARCH3 is an E3 ubiquitin-protein ligase that is broadly expressed at relatively high levels in spleen, colon, and lung. It is localized to early endosomes, binds to MARCH2 and syntaxin 6, and is involved in the regulation of vesicular trafficking and fusion of the transport vesicles in endosomes. Its E2 specificity significantly overlaps that of MARCH2. Pssm-ID: 438360 Cd Length: 51 Bit Score: 45.54 E-value: 8.40e-07

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH8 (MARCH8); MARCH8, also known as membrane-associated RING finger protein 8, membrane-associated RING-CH protein VIII (MARCH-VIII), RING finger protein 178 (RNF178), or cellular modulator of immune recognition (c-MIR), is a membrane-anchored E3 ubiquitin ligase that is broadly expressed. It is a functional homolog of Kaposi"s sarcoma associated-herpes virus encoded proteins, modulator of immune recognition (MIR) 1 and 2, which are involved in the evasion of host immunity. MARCH8 mediates the ubiquitination and down-regulation of immune regulatory cell surface molecules, including major histocompatibility complex class II (MHCII), CD86, transferrin receptor, HLA-DM, and Fas in immune cells. Moreover, MARCH8 controls cell surface expression of some additional proteins. It regulates the ubiquitination and lysosomal degradation of the transferrin receptor (TfR). Tumor necrosis factor-related apoptosis inducing ligand receptor 1 (TRAIL-R1) is also a physiological substrate of the endogenous MARCH8, which regulates the steady-state cell surface expression of TRAIL-R1. Meanwhile, it negatively regulates interleukin-1 (IL-1) beta-induced NF-kappaB activation by targeting the IL-1 receptor accessory protein (IL1RAP) coreceptor for ubiquitination and degradation. Furthermore, MARCH8 functions in the embryo to modulate the strength of cell adhesion by regulating the localization of E-cadherin. In addition, MARCH8 plays a role in the inhibition of inflammatory cytokine production, suggesting a new therapeutic approach to the treatment of rheumatoid arthritis (RA). MARCH8 contains an N-terminal cytoplasmic C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger and two transmembrane domains.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING finger proteins MARCH4, MARCH9, MARCH11, and similar proteins; MARCH4 and MARCH9 are closely related to each other. They downregulate major histocompatibility complex-I (MHC-I). Moreover, MARCH4 and MARCH9, but not other MARCH proteins, can associate with Mult1 and prevent Mult1 expression at the cell surface in a lysine-dependent manner that can be reversed by heat shocking the cells. MARCH11 is a transmembrane RING-finger ubiquitin ligase that is predominantly expressed in developing spermatids in a stage-specific manner and is localized to trans-Golgi network (TGN) vesicles and multivesicular bodies (MVBs). It mediates selective protein sorting via the TGN-MVB transport pathway through its ubiquitin ligase activity. SAMT family proteins have been identified as substrates of MARCH11 in mouse spermatids, suggesting that MARCH11 plays a role in mammalian spermiogenesis. Moreover, MARCH11 targets CD4 for ubiquitination. It also forms complexes with the adaptor protein complex-1 and with fucose-containing glycoproteins including ubiquitinated forms. All subfamily members contain an N-terminal C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, followed by two transmembrane regions.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH6 (MARCH6); MARCH6, also known as membrane-associated RING finger protein 6, membrane-associated RING-CH protein VI (MARCH-VI), RING finger protein 176 (RNF176), protein TEB-4, or Doa10 homolog, is an endoplasmic reticulum (ER)-localized E3 ubiquitin ligase that ubiquitinates ER-associated proteins with a cytoplasmic domain in a ubiquitin-conjugating enzyme 7 (UBC7)-dependent manner), such as Mps2, UBC6, and Ste6. It also regulates its own UBC7-mediated degradation. MARCH6 interacts with ubiquitin-specific protease USP19, which deubiquitinates and stabilizes MARCH6 and inhibits p97-dependent proteasomal degradation. It is also involved in the cholesterol synthesis pathway by controlling the degradation of squalene monooxygenase (SM), and affects 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (HMGCR). Furthermore, it may be a key regulator of thyroid hormone activation in a number of tissues, since it mediates the proteasomal degradation of type 2 iodothyronine deiodinase (D2). MARCH6 contains 14 transmembrane helices and a conserved N-terminal C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, that catalyzes ubiquitin Lys48-specific ligation.

It regulates antigen presentation and T-cell costimulatory functions of dendritic cells by down-regulating the cell surface expression of major histocompatibility complex class II (MHCII) and CD86 molecules. It mediates ubiquitination of MHCII and CD86 in dendritic cells (DCs). This ubiquitination induces MHCII and CD86 endocytosis, lysosomal transport, and degradation. MARCH1 also plays a regulatory role in T cell activation during immune responses, as well as in splenic DC homeostasis. Moreover, MARCH1 may regulate its own expression through dimerization and autoubiquitination. MARCH1 contains an N-terminal cytoplasmic C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger and two transmembrane domains.

RING finger, H2 subclass, found in RING finger protein 111 (RNF111) and similar proteins; RNF111, also known as Arkadia, is a nuclear E3 ubiquitin-protein ligase that targets intracellular effectors and modulators of transforming growth factor beta (TGF-beta)/Nodal-related signaling for polyubiquitination and proteasome-dependent degradation. It acts as an amplifier of Nodal signals, and enhances the dorsalizing activity of limiting amounts of Xnr1, a Nodal homolog, and requires Nodal signaling for its function. The loss of RNF111 results in early embryonic lethality, with defects attributed to compromised Nodal signaling. RNF111 also regulates tumor metastasis by modulation of the TGF-beta pathway. Its ubiquitination can be modulated by the four and a half LIM-only protein 2 (FHL2) that activates TGF-beta signal transduction. Furthermore, RNF111 interacts with the clathrin-adaptor 2 (AP2) complex and regulates endocytosis of certain cell surface receptors, leading to modulation of epidermal growth factor (EGF) and possibly other signaling pathways. In addition, RNF111 has been identified as a small ubiquitin-like modifier (SUMO)-binding protein with clustered SUMO-interacting motifs (SIMs) that together form a SUMO-binding domain (SBD). It thus functions as a SUMO-targeted ubiquitin ligase (STUbL) that directly links nonproteolytic ubiquitylation and SUMOylation in the DNA damage response, as well as triggers degradation of signal-induced polysumoylated proteins, such as the promyelocytic leukemia protein (PML). The N-terminal half of RNF111 harbors three SIMs. Its C-terminal half show high sequence similarity with RING finger protein 165 (RNF165), where it contains two serine rich domains, two nuclear localization signals, an NRG-TIER domain, and a C-terminal C3H2C3-type RING-H2 finger that is required for polyubiqutination and proteasome-dependent degradation of phosphorylated forms of Smad2/3 and three major negative regulators of TGF-beta signaling, Smad7, SnoN and c-Ski.

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH2 (MARCH2); MARCH2, also known as membrane-associated RING finger protein 2, membrane-associated RING-CH protein II (MARCH-II), or RING finger protein 172 (RNF172), is a Golgi-localized, membrane-associated E3 ubiquitin-protein ligase that is involved in endosomal trafficking through the binding of syntaxin 6 (STX6). It is involved in the cystic fibrosis transmembrane conductance regulator (CFTR)-associated ligand (CAL)-mediated ubiquitination and lysosomal degradation of mature CFTR through the association with adaptor proteins CAL and STX6. It also reduces the surface expression of CD86 and the transferrin receptor TFRC and regulates cell surface carvedilol-bound beta2-adrenergic receptor (beta2AR) expression. Moreover, MARCH2 interacts with and ubiquitinates PDZ domains polarity determining scaffold protein DLG1 through its PDZ-binding motif, suggesting it may function as a molecular bridge with ubiquitin ligase activity connecting endocytic tumor suppressor proteins such as syntaxins to DLG1. MARCH2 contains a C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, in the N-terminal cytoplasmic region, two transmembrane domains in the middle region, and a PDZ-binding motif at the C-terminus.

RING finger, H2 subclass, found in RING finger proteins RNF111, RNF165, and similar proteins; The family includes RING finger proteins RNF111, RNF165, and similar proteins. RNF111, also known as Arkadia, is a nuclear E3 ubiquitin-protein ligase that targets intracellular effectors and modulators of transforming growth factor beta (TGF-beta)/Nodal-related signaling for polyubiquitination and proteasome-dependent degradation. It also interacts with the clathrin-adaptor 2 (AP2) complex and regulates endocytosis of certain cell surface receptors, leading to modulation of epidermal growth factor (EGF) and possibly other signaling pathways. The N-terminal half of RNF111 harbors three SUMO-interacting motifs (SIMs). It thus functions as a SUMO-targeted ubiquitin ligase (STUbL) that directly links nonproteolytic ubiquitylation and SUMOylation in the DNA damage response, as well as triggers degradation of signal-induced polysumoylated proteins, such as the promyelocytic leukemia protein (PML). RNF165, also known as Arkadia-like 2, Arkadia2, or Ark2C, is an E3 ubiquitin ligase with homology to the C-terminal half of RNF111. It is expressed specifically in the nervous system, and can serve to amplify neuronal responses to specific signals. It acts as a positive regulator of bone morphogenetic protein (BMP)-Smad signaling that is involved in motor neuron (MN) axon elongation. Both RNF165 and RNF111 contain a C-terminal C3H2C3-type RING-H2 finger. Pssm-ID: 438137 [Multi-domain] Cd Length: 46 Bit Score: 34.31 E-value: 7.45e-03

lantibiotic immunity ABC transporter MutG family permease (also called ABC-2 transporter MutG family permease) subunit; This subfamily includes lantibiotic ABC transporter permease subunit MutG which is a highly hydrophobic, integral membrane protein, and part of the bacitracin ABC transport system that confers resistance to the Gram-positive bacteria in which this system operates, specifically to lantibiotic mutacin. Lantibiotics are small peptides, produced by Gram-positive bacteria, which are ribosomally-synthesized as pre-peptides and act by disrupting membrane integrity. Genes encoding the lantibiotic ABC transporter subunits are highly organized in operons containing all the genes required for maturation, transport, immunity, and synthesis. For example, in Streptococcus mutans CH43, the lantibiotic mutacin is active against other Gram-positive bacteria via various modes of actions; however, its self-protection against the pore-forming mutacin is mediated by the ABC transporter composed of MutF, MutE, and MutG. This subfamily includes the MutG permease subunit that transports mutacin to the surface and expels it from the membrane. Pssm-ID: 409633 Cd Length: 237 Bit Score: 37.90 E-value: 7.58e-03

RING-CH finger, H2 subclass (C4HC3-type), found in membrane-associated RING-CH3 (MARCH3); MARCH3, also known as membrane-associated RING finger protein 3, or membrane-associated RING-CH protein III (MARCH-III), or RING finger protein 173 (RNF173), is an E3 ubiquitin-protein ligase that is broadly expressed and is found at relatively high levels in spleen, colon, and lung. It is localized to early endosomes, binds to MARCH2 and syntaxin 6, and is involved in the regulation of vesicular trafficking and fusion of the transport vesicles in endosomes. MARCH3 is the closest homolog of MARCH2 and it is also a functional homolog of K3 and K5 viral ubiquitin E3 ligases related to immune-evasion strategies used by Kaposi's sarcoma-associated herpesvirus (KSHV). Its E2 specificity significantly overlaps that of MARCH2. MARCH3 contains a C4HC3-type RING-CH finger, also known as vRING or RINGv, a variant of C3H2C3-type RING-H2 finger, in the N-terminal cytoplasmic region, two transmembrane domains in the middle region, and a PDZ-binding motif at the C-terminus. The RING-CH finger and PDZ-binding motif are essential for the subcellular localization of MARCH3 and the inhibitory effect on transferrin uptake.

RING finger, H2 subclass, found in RING finger protein 13 (RNF13) and similar proteins; RNF13 is a widely expressed membrane-associated E3 ubiquitin-protein ligase that is functionally significant in the regulation of cancer development, muscle cell growth, and neuronal development. Its expression is developmentally regulated during myogenesis and is upregulated in various tumors. RNF13 negatively regulates cell proliferation through its E3 ligase activity. It functions as an important regulator of inositol-requiring transmembrane kinase/endonuclease IRE1alpha, mediating endoplasmic reticulum (ER) stress-induced apoptosis through the activation of the IRE1alpha-TRAF2-JNK signaling pathway. Moreover, RNF13 is involved in the regulation of the soluble N-ethylmaleimide-sensitive fusion protein attachment protein receptor (SNARE) complex via the ubiquitination of snapin, a SNAP25-interacting protein, which thereby controls synaptic function. In addition, RNF13 participates in regulating the function of satellite cells by modulating cytokine composition. RNF13 is evolutionarily conserved among many metazoans and contains an N-terminal signal peptide, a protease-associated (PA) domain, a transmembrane (TM) domain and a C-terminal C3H2C3-type RING-H2 finger domain followed by a putative PEST sequence.
