Summary: Predicted to enable phosphatase binding activity and phospholipid binding activity. Involved in synaptic vesicle endocytosis. Acts upstream of or within learning. Located in synaptic vesicle. Is active in glutamatergic synapse; photoreceptor ribbon synapse; and presynaptic endocytic zone. Is expressed in several structures, including allantois; brain; genitourinary system; liver; and septum transversum. Orthologous to human AMPH (amphiphysin).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
