Calcium-dependent secretion activator 2 is a protein that in humans is encoded by the CADPS2 gene.[1]


This gene encodes a member of the calcium-dependent activator of secretion (CAPS) protein family, which are calcium-binding proteins that regulate the exocytosis of synaptic and dense-core vesicles in neurons and neuroendocrine cells.[1]


This gene interacts with brain-derived neurotrophic factor.

Clinical significance[edit]

Cadps2 has been linked to autism[2] and is in the 7q autism susceptibility locus (AUTS1). However, the finding of aberrant CADPS2 splicing was not found to be significant in another study.[3]

A knockout mouse model was found to have autistic-like characteristics.[2]

CADPS2 has been linked to human and mouse brain structure in two large genomic studies.[4][5]
