Summary: Enables calcium ion binding activity; calcium-dependent phospholipid binding activity; and transcription corepressor binding activity. Involved in several processes, including positive regulation of synaptic vesicle recycling; presynaptic active zone assembly; and regulation of endosome size. Located in several cellular components, including cytoskeleton of presynaptic active zone; distal axon; and rod spherule. Is active in glutamatergic synapse; parallel fiber to Purkinje cell synapse; and presynaptic active zone cytoplasmic component. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 3. Orthologous to human PCLO (piccolo presynaptic cytomatrix protein).

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.
