| Research Abstract |
We analyzed cellular function and biological significance of secretion-associated protein CAPS and reported the following findings.
1) CAPS2 promotes kinetics of activity-dependent secretion of brain-derived neuotrophic factor BDNF. CAPS2 KO mice have impairments in development and function of GABAergic inhibitory circuits and exhibit increased anxiety-like phenotype.
2) In addition to involvement in exocytosis of dense core vesicles, CAPS associates with small GTPase Arf4/5 and is associated with biogenesis and trafficking of dense-core vesicles in the trans-Golgi network.
