PCLO

Protein piccolo is a protein that in humans is encoded by the PCLO gene.[4][5][6]
Function
Synaptic vesicles dock and fuse in the active zone of the plasma membrane at chemical synapses. The presynaptic cytoskeletal matrix (PCM), which is associated with the active zone and is situated between synaptic vesicles, is thought to be involved in maintaining the neurotransmitter release site in register with the postsynaptic reception apparatus. The cycling of synaptic vesicles is a multistep process involving a number of proteins (see MIM 603215). Among the components of the PCM that orchestrate these events are Bassoon (BSN; MIM 604020), RIM (RIMS1; MIM 606629), Oboe (RIMS2; MIM 606630), and Piccolo (PCLO).[supplied by OMIM][6]
Interactions
PCLO has been shown to interact with GIT1.[7]
Clinical relevance
Recurrent mutations in this gene have been associated to cases of diffuse large B-cell lymphoma.[8]
