Pclo Gene Summary [Rat]
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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pclo often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
