Summary: Enables profilin binding activity. A structural constituent of presynaptic active zone. Involved in presynaptic actin cytoskeleton organization; protein localization to synapse; and synaptic vesicle clustering. Acts upstream of or within cytoskeleton organization; insulin secretion; and regulation of exocytosis. Located in postsynaptic density. Is expressed in nervous system and sensory organ. Human ortholog(s) of this gene implicated in pontocerebellar hypoplasia type 3. Orthologous to human PCLO (piccolo presynaptic cytomatrix protein).

Piccolo puncta sandwiched Bassoon puncta and aligned in a Piccolo-Bassoon-Piccolo structure in adult neuromuscular junctions (NMJs). P/Q-type voltage-gated calcium channel (VGCC) puncta colocalized with Bassoon puncta. The P/Q-type VGCC and Bassoon protein levels decreased significantly in NMJs from aged mouse. In contrast, the Piccolo levels in NMJs from aged mice were comparable to levels in adult mice.

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.
