. "SEQUENCE 352 AA; 39962 MW; F3AE2353E1EB7CF3 CRC64;"^^ . "FUNCTION: Implicated in synaptic vesicle endocytosis. May recruit other proteins to membranes with high curvature. SUBUNIT: Monomer; in cytoplasm. Homodimer; when associated with membranes (By similarity). Interacts with OPHN1 (By similarity). Interacts with SYNJ1 and DNM1. Interacts with MAP4K3; the interaction appears to regulate MAP4K3-mediated JNK activation. Interacts with PDCD6IP. Interacts with ATX2. SUBCELLULAR LOCATION: Cytoplasm. Membrane; Peripheral membrane protein. Note=Concentrated in presynaptic nerve terminals in neurons. TISSUE SPECIFICITY: Brain, mostly in frontal cortex. Expressed at high level in fetal cerebellum. DOMAIN: An N-terminal amphipathic helix, the BAR domain and a second amphipathic helix inserted into helix 1 of the BAR domain (N-BAR domain) induce membrane curvature and bind curved membranes. The BAR domain dimer forms a rigid crescent shaped bundle of helices with the pair of second amphipathic helices protruding towards the membrane-binding surface. MISCELLANEOUS: HeLa cells expressing the N-BAR domain of SH3GL2 show tubulation of the plasma membrane. The N-BAR domain binds liposomes and induces formation of tubules from liposomes. The N- terminal amphipathic helix is required for liposome binding. The second amphipathic helix enhances liposome tubulation. SIMILARITY: Belongs to the endophilin family. SIMILARITY: Contains 1 BAR domain. SIMILARITY: Contains 1 SH3 domain. GENE SYNONYMS:SH3GL2 CNSA2 SH3D2A.
