May serve as a scaffold protein for MADD and RAB3GA on synaptic vesicles . Plays a role in the brain as a key controller of neuronal and endocrine homeostatic processes (By similarity).
Subcellular locations: Cytoplasmic vesicle, Secretory vesicle, Synaptic vesicle membrane, Cytoplasmic vesicle, Secretory vesicle, Neuronal dense core vesicle
The external layer of the inferior boundary for the hypothalamus part of the human brain (the so called median eminence (ME)) displayed a punctate pattern of expression; expression also observed in the cell bodies lining the third ventricle, in the long processes extending from these cell bodies toward the external layer of the ME, in small clear vesicles, and in large dense core vesicles.
