LEM (Lap2/Emerin/Man1) domain found in lamina-associated polypeptide 2 (LAP2), LEM domain-containing protein 1 (LEMP-1) and similar proteins; This CD corresponds to the LEM domain of LAP2, LEMP-1 and similar proteins. LAP2, also termed thymopoietin (TP), or thymopoietin-related peptide (TPRP), is composed of isoform alpha and isoforms beta/gamma and may be involved in chromatin organization and post-mitotic reassembly. Some of LAP2 isoforms are inner nuclear membrane proteins that can bind to nuclear lamins and chromatin, while others are non-membrane nuclear polypeptides. All LAP2 isoforms contain an N-terminal LEM domain that is connected to a highly divergent LEM-like domain by an unstructured linker. Although LEM and LEM-like domains share the same structural fold composed of two large parallel alpha helices, the biochemical nature of the solvent-accessible residues is completely different, indicating that the two domains may target different protein surfaces. The LEM domain interacts with the nonspecific DNA binding protein barrier-to-autointegration factor (BAF) while the LEM-like domain is involved in chromosome binding. LEMP-1, also termed cancer/testis antigen 50 (CT50), is encoded by LEMD1, a novel testis-specific gene expressed in colorectal cancers. It may function as a cancer-testis antigen for immunotherapy of colorectal carcinoma (CRC). LEMP-1 contains an N-terminal LEM domain. Pssm-ID: 240587 Cd Length: 42 Bit Score: 69.64 E-value: 9.50e-17

LEM (Lap2/Emerin/Man1) domain found in emerin, lamina-associated polypeptide 2 (LAP2), inner nuclear membrane protein Man1 and similar proteins; The family corresponds to a group of inner nuclear membrane proteins containing LEM domain. Emerin occurs in four phosphorylated forms and plays a role in cell cycle-dependent events. It is absent from the inner nuclear membrane in most patients with X-linked muscular dystrophy. Emerin interacts with A-type and B-type lamins. Man1, also termed LEM domain-containing protein 3 (LEMD3) is an integral protein of the inner nuclear membrane that binds to nuclear lamins and emerin, thus playing a role in nuclear organization. LAP2, also termed thymopoietin (TP), or thymopoietin-related peptide (TPRP), is composed of isoform alpha and isoforms beta/gamma and may be involved in chromatin organization and post-mitotic reassembly. Some LAP2 isoforms are inner nuclear membrane proteins that can bind to nuclear lamins and chromatin, while others are non-membrane nuclear polypeptides. This family also contains LEM domain-containing protein LEMP-1 and LEM2. LEMP-1, also termed cancer/testis antigen 50 (CT50), is encoded by LEMD1, a novel testis-specific gene expressed in colorectal cancers. LEMP-1 may function as a cancer-testis antigen for immunotherapy of colorectal carcinoma (CRC). LEM2, also termed LEMD2, is a novel Man1-related ubiquitously expressed inner nuclear membrane protein required for normal nuclear envelope morphology. Association with lamin A is required for its proper nuclear envelope localization while its binding to lamin C plays an important role in the organization of lamin A/C complexes. Some uncharacterized LEM domain-containing proteins are also included in this family. Unlike other family members, these harbor an ankyrin repeat region that may mediate protein-protein interactions.

LEM (Lap2/Emerin/Man1) domain found in emerin; This CD corresponds to the LEM domain that is critical for binding to lamin A/C and is also involved in interaction with the DNA binding protein barrier-to-autointegration factor (BAF). Emerin is an inner nuclear membrane protein that occurs in four differently phosphorylated forms and plays a role in cell cycle-dependent events. It is absent from the inner nuclear membrane in most patients with X-linked muscular dystrophy. Emerin interacts with A-type and B-type lamins. It contains an N-terminal LEM domain followed by a poly-serine segment, a region rich in hydrophobic amino acids comprising the nuclear localization signal (NLS) followed by another poly-serine segment, and a C-terminal transmembrane region.

LEM (Lap2/Emerin/Man1) domain found in LEM domain-containing protein 2 (LEM2); This CD corresponds to the LEM domain that is responsible for the interaction with chromatin protein barrier-to-autointegration factor (BAF). LEM2, also termed LEMD2, is a novel Man1-related ubiquitously expressed inner nuclear membrane protein required for normal nuclear envelope morphology. Association with lamin A is required for its proper nuclear envelope localization. It also binds to lamin C and plays an important role in the organization of lamin A/C complexes. LEM2 contains an N-terminal LEM domain, two putative transmembrane domains and a MAN1-Src1p C-terminal (MSC) domain, but lacks the Man1-specific C-terminal RNA recognition motif (RRM).

LEM (Lap2/Emerin/Man1) domain found in inner nuclear membrane protein Man1; This CD corresponds to the LEM domain of Man1 and similar proteins. Man1, also termed LEM domain-containing protein 3 (LEMD3), is an integral protein of the inner nuclear membrane that binds to nuclear lamins and emerin, thus playing a role in nuclear organization. It is part of a protein complex essential for chromatin organization and cell division. It also functions as an important negative regulator for the transforming growth factor beta (TGF-beta) /activin/Nodal signaling pathway and bone morphogenetic protein (BMP) signaling pathway by directly interacting with chromatin-associated proteins and transcriptional regulators, including the R-Smads, Smad1, Smad2, and Smad3. Man1 is a unique type of left/right (LR) signaling regulator that acts on the inner nuclear membrane. Furthermore, Man1 plays a crucial role in angiogenesis. The vascular remodeling can be regulated at the inner nuclear membrane through interactions between Man1 and Smads. Man1 contains an N-terminal LEM domain, two putative transmembrane domains, a Man1-Src1p C-terminal (MSC) domain, and a C-terminal RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain). The LEM domain interacts with DNA and chromatin-binding protein Barrier-to-Autointegration Factor, and is also necessary for efficient localization of Man1 in the inner nuclear membrane. It has been shown that the C-terminal nucleoplasmic region of Man1 exhibits a DNA binding winged helix domain and is responsible for both, DNA- and Smad-binding.
