 1-181 1.17e-89

The Bin/Amphiphysin/Rvs (BAR) domain, a dimerization module that binds membranes and detects membrane curvature; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions including organelle biogenesis, membrane trafficking or remodeling, and cell division and migration. Mutations in BAR containing proteins have been linked to diseases and their inactivation in cells leads to altered membrane dynamics. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in amphiphysins and endophilins, among others. BAR domains are also frequently found alongside domains that determine lipid specificity, such as the Pleckstrin Homology (PH) and Phox Homology (PX) domains which are present in beta centaurins (ACAPs and ASAPs) and sorting nexins, respectively. A FES-CIP4 Homology (FCH) domain together with a coiled coil region is called the F-BAR domain and is present in Pombe/Cdc15 homology (PCH) family proteins, which include Fes/Fes tyrosine kinases, PACSIN or syndapin, CIP4-like proteins, and srGAPs, among others. The Inverse (I)-BAR or IRSp53/MIM homology Domain (IMD) is found in multi-domain proteins, such as IRSp53 and MIM, that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions. The I-BAR domain induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. BAR domains that also serve as protein interaction domains include those of arfaptin and OPHN1-like proteins, among others, which bind to Rac and Rho GAP domains, respectively.

 1-181 1.17e-89

The Bin/Amphiphysin/Rvs (BAR) domain of Endophilin-B2; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Endophilins play roles in synaptic vesicle formation, virus budding, mitochondrial morphology maintenance, receptor-mediated endocytosis inhibition, and endosomal sorting. Endophilins contain an N-terminal N-BAR domain (BAR domain with an additional N-terminal amphipathic helix), followed by a variable region containing proline clusters, and a C-terminal SH3 domain. They are classified into two types, A and B. Vertebrates contain two endophilin-B isoforms. Endophilin-B proteins are cytoplasmic proteins expressed mainly in the heart, placenta, and skeletal muscle. Endophilin-B2, also called SH3GLB2 (SH3-domain GRB2-like endophilin B2), is a cytoplasmic protein that interacts with the apoptosis inducer Bax. It is overexpressed in prostate cancer metastasis and has been identified as a cancer antigen with potential utility in immunotherapy. Endophilin-B2 forms homo- and heterodimers (with endophilin-B1) through its BAR domain, which can bind and bend membranes.

The Bin/Amphiphysin/Rvs (BAR) domain, a dimerization module that binds membranes and detects membrane curvature; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions including organelle biogenesis, membrane trafficking or remodeling, and cell division and migration. Mutations in BAR containing proteins have been linked to diseases and their inactivation in cells leads to altered membrane dynamics. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in amphiphysins and endophilins, among others. BAR domains are also frequently found alongside domains that determine lipid specificity, such as the Pleckstrin Homology (PH) and Phox Homology (PX) domains which are present in beta centaurins (ACAPs and ASAPs) and sorting nexins, respectively. A FES-CIP4 Homology (FCH) domain together with a coiled coil region is called the F-BAR domain and is present in Pombe/Cdc15 homology (PCH) family proteins, which include Fes/Fes tyrosine kinases, PACSIN or syndapin, CIP4-like proteins, and srGAPs, among others. The Inverse (I)-BAR or IRSp53/MIM homology Domain (IMD) is found in multi-domain proteins, such as IRSp53 and MIM, that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions. The I-BAR domain induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. BAR domains that also serve as protein interaction domains include those of arfaptin and OPHN1-like proteins, among others, which bind to Rac and Rho GAP domains, respectively.

The Bin/Amphiphysin/Rvs (BAR) domain of Endophilin-A; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Endophilins are accessory proteins, localized at synapses, which interact with the endocytic proteins, dynamin and synaptojanin. They are essential for synaptic vesicle formation from the plasma membrane. They interact with voltage-gated calcium channels, thus linking vesicle endocytosis to calcium regulation. They also play roles in virus budding, mitochondrial morphology maintenance, receptor-mediated endocytosis inhibition, and endosomal sorting. Endophilins contain an N-terminal N-BAR domain (BAR domain with an additional N-terminal amphipathic helix), followed by a variable region containing proline clusters, and a C-terminal SH3 domain. They are classified into two types, A and B. Vertebrates contain three endophilin-A isoforms. Endophilin-A proteins are enriched in the brain and play multiple roles in receptor-mediated endocytosis. They tubulate membranes and regulate calcium influx into neurons to trigger the activation of the endocytic machinery. They are also involved in the sorting of plasma membrane proteins, actin filament assembly, and the uncoating of clathrin-coated vesicles for fusion with endosomes. The BAR domains of endophilin-A1 and A3 form crescent-shaped dimers that can detect membrane curvature and drive membrane bending.

Endophilin-A2 (or endophilin-2) is also referred to as SH3P8 (SH3 domain containing protein 8) or SH3GL1 (SH3 domain containing Grb2-like protein 1). It localizes to presynaptic nerve terminals and forms heterodimers with endophilin-A1 through their BAR domains. Endophilin-A2 binds dynamin 1, synaptojanin 1, and the beta1-adrenergic receptor cytoplasmic tail through its SH3 domain.

 1-74 1.92e-07

The Bin/Amphiphysin/Rvs (BAR) domain of Rich-like Rho GTPase Activating Proteins; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. This subfamily is composed of Rho and Rac GTPase activating proteins (GAPs) with similarity to GAP interacting with CIP4 homologs proteins (Rich). Members contain an N-terminal BAR domain, followed by a Rho GAP domain, and a C-terminal prolin-rich region. Vertebrates harbor at least three Rho GAPs in this subfamily including Rich1, Rich2, and SH3-domain binding protein 1 (SH3BP1). Rich1 and Rich2 play complementary roles in the establishment and maintenance of cell polarity. Rich1 is a Cdc42- and Rac-specific GAP that binds to polarity proteins through the scaffold protein angiomotin and plays a role in maintaining the integrity of tight junctions. Rich2 is a Rac GAP that interacts with CD317 and plays a role in actin cytoskeleton organization and the maintenance of microvilli in polarized epithelial cells. SH3BP1 is a Rac GAP that inhibits Rac-mediated platelet-derived growth factor (PDGF)-induced membrane ruffling. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions. The BAR domain of Rich1 has been shown to form oligomers, bind membranes and induce membrane tubulation.

Endophilin-A3 (or endophilin-3) is also referred to as SH3P13 (SH3 domain containing protein 13) or SH3GL3 (SH3 domain containing Grb2-like protein 3). It regulates Arp2/3-dependent actin filament assembly during endocytosis. It binds N-WASP through its SH3 domain and enhances the ability of N-WASP to activate the Arp2/3 complex. Endophilin-A3 co-localizes with the vesicular glutamate transporter 1 (VGLUT1), and may play an important role in the synaptic release of glutamate.

Inverse (I)-BAR, also known as the IRSp53/MIM homology Domain (IMD), a dimerization module that binds and bends membranes; Inverse (I)-BAR (or IMD) is a member of the Bin/Amphiphysin/Rvs (BAR) domain family. It is a dimerization and lipid-binding module that bends membranes and induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. IMD domains are found in Insulin Receptor tyrosine kinase Substrate p53 (IRSp53), Missing in Metastasis (MIM), and Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2-like (BAIAP2L) proteins. These are multi-domain proteins that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. Most members contain an N-terminal IMD, an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus, exccept for MIM which does not carry an SH3 domain. Some members contain additional domains and motifs. The IMD domain binds and bundles actin filaments, binds membranes and produces membrane protrusions, and interacts with the small GTPase Rac.
