Summary: Enables several functions, including SH2 domain binding activity; anion binding activity; and clathrin binding activity. Involved in several processes, including negative regulation of phospholipase activity; positive regulation of cellular component organization; and positive regulation of synaptic vesicle clustering. Located in several cellular components, including cytoplasmic vesicle; postsynaptic density; and presynaptic active zone membrane. Is active in Schaffer collateral - CA1 synapse; parallel fiber to Purkinje cell synapse; and postsynaptic membrane. Is extrinsic component of presynaptic endocytic zone membrane. Biomarker of middle cerebral artery infarction. Orthologous to human SNAP91 (synaptosome associated protein 91). [provided by Alliance of Genome Resources, Apr 2022]

Neurons with reduced AP180 had smaller Synaptophysin::EGFP-illuminated puncta. Synaptic vesicles were enlarged & their density and size were reduced.
Title: Reduction of AP180 and CALM produces defects in synaptic vesicle size and density.
AP180 purified from rat brain contains a phosphorylated O-GlcNAc (O-GlcNAc-P) within a highly conserved sequence
Title: A novel post-translational modification in nerve terminals: O-linked N-acetylglucosamine phosphorylation.
These findings suggest that AP180 levels and synaptic distribution are highly sensitive to neuronal activity.
Title: Neuronal activity and the expression of clathrin-assembly protein AP180.
These results identify the developmental stage of AP180 and CALM expression and suggest that each protein has distinct functions in neural development.
Title: Clathrin assembly proteins AP180 and CALM in the embryonic rat brain.
Knockdown of AP180 primarily impairs axonal development, whereas reducing CALM levels results in dendritic dystrophy. endocytosis is reduced in both AP180-deficient and CALM-deficient neurons.
Title: Clathrin assembly protein AP180 and CALM differentially control axogenesis and dendrite outgrowth in embryonic hippocampal neurons.
High expression levels of AP180 were found in hippocampal tissues as early as embryonic day 18; AP180 was found in synapses at all developmental stages and in nonsynaptic growing processes.
Title: AP180 and CALM in the developing hippocampus: expression at the nascent synapse and localization to trafficking organelles.
The expression of AP180 and AP-2 in the clathrin endocytic pathway might aid synaptic vesicle reformation via efficient assembly of clathrin, thus controlling the size of assembled vesicles and recovering SV components.
Title: High-resolution localization of clathrin assembly protein AP180 in the presynaptic terminals of mammalian neurons.
AP180 is located predominantly in presynaptic profiles, whereas CALM is found nonselectively in pre- and postsynaptic profiles and also in perisynaptic processes.
Title: Synaptic distribution of the endocytic accessory proteins AP180 and CALM.

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.
