Summary: Enables several functions, including 1-phosphatidylinositol binding activity; clathrin heavy chain binding activity; and protein kinase binding activity. Involved in clathrin coat assembly and neurotransmitter secretion. Predicted to be located in several cellular components, including neuronal cell body; postsynaptic density; and presynaptic active zone membrane. Predicted to be part of AP-2 adaptor complex. Predicted to be active in several cellular components, including Schaffer collateral - CA1 synapse; cytoplasmic vesicle; and parallel fiber to Purkinje cell synapse. Predicted to be extrinsic component of presynaptic endocytic zone membrane. Is expressed in several structures, including central nervous system; gut; limb; peripheral nervous system ganglion; and urinary system. Orthologous to human SNAP91 (synaptosome associated protein 91). [provided by Alliance of Genome Resources, Nov 2024]

AP180 promotes release site clearance and clathrin-dependent vesicle reformation in mouse cochlear inner hair cells.
Title: AP180 promotes release site clearance and clathrin-dependent vesicle reformation in mouse cochlear inner hair cells.
Confinement within the presynaptic bouton is mediated in part by synaptic vesicle protein association with the clathrin-based endocytic machinery to limit diffusional spread of newly exocytosed SV proteins.
Title: Diffusional spread and confinement of newly exocytosed synaptic vesicle proteins.
The clathrin assembly role of AP180 is mediated by a long disordered C-terminal assembly domain.
Title: The ∼ 16 kDa C-terminal sequence of clathrin assembly protein AP180 is essential for efficient clathrin binding.

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.
