Background InformationAmphiphysin is a nerve terminal-enriched protein thought to be involved in synaptic vesicle endocytosis. One of three amphiphysin homologs, amphiphysin II may interact with amphiphysin I in order to regulate synaptic vesicle endocytosis. During clathrin-mediated endocytosis, amphiphysin has been reported to bind to a component of the clathrin coat, clathrin assembly protein 2. Mutations in the expression of amphiphysin II may be causal to defects in the endocytosis pathway. Expression of amphiphysin II has been observed in neurons along with some endocrine cell types and spermatocytes.

Entrez Gene Number
Entrez Gene SummaryThis gene encodes several isoforms of a nucleocytoplasmic adaptor protein, one of which was initially identified as a MYC-interacting protein with features of a tumor suppressor. Isoforms that are expressed in the central nervous system may be involved in synaptic vesicle endocytosis and may interact with dynanim, synaptojanin, endophilin, and clathrin. Isoforms that are expressed in muscle and ubiquitously expressed isoforms localize to the cytoplasm and nucleus and activate a caspase-independent apoptotic process. Studies in mouse suggest that this gene plays an important role in cardiac muscle development. Alternate splicing of the gene results in ten transcript variants encoding different isoforms. Aberrant splice variants expressed in tumor cell lines have also been described. [provided by RefSeq].

UniProt Number
UniProt SummaryFUNCTION: May be involved in regulation of synaptic vesicle endocytosis. May act as a tumor suppressor and inhibits malignant cell transformation.

SUBUNIT STRUCTURE: Heterodimer with AMPH. Binds SH3GLB1 By similarity. Interacts (via SH3 domain) with SYNJ1. Interacts (via SH3 domain) with DNM1. Isoform IIA interacts with CLTC. Isoform IIB does not interact with CLTC. Isoform IIC1 does not interact with CLTC. Isoform IIC2 does not interact with CLTC. Interacts with AP2A2. Interacts with AP2B1. Interacts with MYC (via N-terminal transactivation domain); the interaction requires of in a the integrity of the conserved MYC box regions 1 and 2. Interacts with BIN2. Interacts (SH3 domain) with HCV NS5A.

SUBCELLULAR LOCATION: Isoform BIN1: Nucleus.

Isoform IIA: Cytoplasm.

TISSUE SPECIFICTY: Ubiquitous. Highest expression in the brain and muscle. Isoform IIA is expressed only in the brain where it is concentrated in axon initial segments and nodes of Ranvier. Isoform BIN1 is widely expressed with highest expression in skeletal muscle.

PTM: Phosphorylated by protein kinase C By similarity.

INVOLVEMENT IN DISEASE: Defects in BIN1 are the cause of centronuclear myopathy autosomal recessive (ARCNM) [MIM:255200]; also known as autosomal recessive myotubular myopathy. Centronuclear myopathies are congenital muscle disorders characterized by progressive muscular weakness and wasting involving mainly limb girdle, trunk, and neck muscles. It may also affect distal muscles. Weakness may be present during childhood or adolescence or may not become evident until the third decade of life. Ptosis is a frequent clinical feature. The most prominent histopathologic features include high frequency of centrally located nuclei in muscle fibers not secondary to regeneration, radial arrangement of sarcoplasmic strands around the central nuclei, and predominance and hypotrophy of type 1 fibers.

SEQUENCE SIMILARITIES: Contains 1 BAR domain.

Contains 1 SH3 domain.
Molecular WeightIt is well established (Ramjaun, 1997) that both Amphiphysin I and II run substantially slower on SDS-PAGE with a larger apparent molecular weight than the predicted molecular weights.
