Component of a transport protein particle (TRAPP) complex that may function in specific stages of inter-organelle traffic (, ). Specifically involved in the early development of neural circuitry, likely by controlling the frequency and amplitude of intracellular calcium transients implicated in the regulation of neuron differentiation and survival (Probable).
Subcellular locations: Golgi apparatus, Cis-Golgi network, Endoplasmic reticulum
Both isoforms are expressed ubiquitously (at transcript level), isoform 1 being the most predominant . Expressed in the fetal brain and different regions of the adult brain and spinal cord .
