The Bin/Amphiphysin/Rvs (BAR) domain of Amphiphysin I and II; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Amphiphysins function primarily in endocytosis and other membrane remodeling events. They contain an N-terminal BAR domain with an additional N-terminal amphipathic helix (an N-BAR), a variable central domain, and a C-terminal SH3 domain. Amphiphysin I proteins, enriched in the brain and nervous system, contain domains that bind clathrin, Adaptor Protein complex 2 (AP2), dynamin and synaptojanin. They function in synaptic vesicle endocytosis. Some amphiphysin II isoforms, also called Bridging integrator 1 (Bin1), are localized in many different tissues and may function in intracellular vesicle trafficking. In skeletal muscle, Bin1 plays a role in the organization and maintenance of the T-tubule network. The N-BAR domain of amphiphysin forms a curved dimer with a positively-charged concave face that can drive membrane bending and curvature. Human autoantibodies to amphiphysin-1 hinder GABAergic signaling and contribute to the pathogenesis of paraneoplastic stiff-person syndrome. Mutations in amphiphysin-2 (BIN1) are associated with autosomal recessive centronuclear myopathy. : Pssm-ID: 153295 Cd Length: 211 Bit Score: 425.89 E-value: 3.12e-151

The Bin/Amphiphysin/Rvs (BAR) domain of Bridging integrator 2; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Bridging integrator 2 (Bin2) is a BAR domain containing protein that is mainly expressed in hematopoietic cells. It is upregulated during granulocyte differentiation and is thought to function primarily in this lineage. The BAR domain of Bin2 is closely related to the BAR domains of amphiphysins, which function primarily in endocytosis and other membrane remodeling events. Amphiphysins contain an N-terminal BAR domain with an additional N-terminal amphipathic helix (an N-BAR), a variable central domain, and a C-terminal SH3 domain. Unlike amphiphysins, Bin2 does not appear to contain a C-terminal SH3 domain. Amphiphysin I proteins, enriched in the brain and nervous system, function in synaptic vesicle endocytosis. Some amphiphysin II isoforms, also called Bridging integrator 1 (Bin1), function in intracellular vessicle trafficking. Bin2 can form a stable complex with Bin1 in cells but cannot replace the function of Bin1, and thus, appears to harbor a nonredundant function. The N-BAR domain of amphiphysin forms a curved dimer with a positively-charged concave face that can drive membrane bending and curvature.

The Bin/Amphiphysin/Rvs (BAR) domain of Saccharomyces cerevisiae Reduced viability upon starvation protein 161 and similar proteins; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. This subfamily is composed of fungal proteins with similarity to Saccharomyces cerevisiae Reduced viability upon starvation protein 161 (Rvs161p) and Schizosaccharomyces pombe Hob3 (homolog of Bin3). S. cerevisiae Rvs161p plays a role in regulating cell polarity, actin cytoskeleton polarization, vesicle trafficking, endocytosis, bud formation, and the mating response. It forms a heterodimer with another BAR domain protein Rvs167p. Rvs161p and Rvs167p share common functions but are not interchangeable. Their BAR domains cannot be replaced with each other and the overexpression of one cannot suppress the mutant phenotypes of the other. S. pombe Hob3 is important in regulating filamentous actin localization and may be required in activating Cdc42 and recruiting it to cell division sites. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions.

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.

Rvs161p and Rvs167p share common functions but are not interchangeable. Their BAR domains cannot be replaced with each other and the overexpression of one cannot suppress the mutant phenotypes of the other. Rvs167p also interacts with the GTPase activating protein (GAP) Gyp5p, which is involved in ER to Golgi vesicle trafficking. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions.

The Bin/Amphiphysin/Rvs (BAR) domain of Dynamin Binding Protein; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. DyNamin Binding Protein (DNMBP), also called Tuba, is a Cdc42-specific Guanine nucleotide Exchange Factor (GEF) that binds dynamin and various actin regulatory proteins. It serves as a link between dynamin function, Rho GTPase signaling, and actin dynamics. It plays an important role in regulating cell junction configuration. DNMBP contains BAR and SH3 domains as well as a Dbl Homology domain (DH domain), which harbors GEF activity. 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 DNMBP may be involved in binding to membranes. The gene encoding DNMBP is a candidate gene for late onset Alzheimer's disease.

The Bin/Amphiphysin/Rvs (BAR) domain of Bridging integrator 3; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Bridging integrator 3 (Bin3) is widely expressed in many tissues except in the brain. It plays roles in regulating filamentous actin localization and in cell division. In humans, the Bin3 gene is located in chromosome 8p21.3, a region that is implicated in cancer suppression. Homozygous inactivation of the Bin3 gene in mice led to the development of cataracts and an increased likelihood of lymphomas during aging, suggesting a role for Bin3 in lens development and cancer suppression. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions.

The Bin/Amphiphysin/Rvs (BAR) domain of Sorting Nexin 6; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. Sorting nexins (SNXs) are Phox homology (PX) domain containing proteins that are involved in regulating membrane traffic and protein sorting in the endosomal system. SNXs differ from each other in their lipid-binding specificity, subcellular localization and specific function in the endocytic pathway. A subset of SNXs also contain BAR domains. The PX-BAR structural unit determines the specific membrane targeting of SNXs. SNX6 forms a stable complex with SNX1 and may be a component of the retromer complex, a membrane coat multimeric complex required for endosomal retrieval of lysosomal hydrolase receptors to the Golgi, acting as a mammalian equivalent of yeast Vsp17p. It interacts with the receptor serine/threonine kinases from the transforming growth factor-beta family. It also plays roles in enhancing the degradation of EGFR and in regulating the activity of Na,K-ATPase through its interaction with Translationally Controlled Tumor Protein (TCTP). BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions.
