Identification of a high-affinity network of secretagogin-binding proteins involved in vesicle secretion.
Secretagogin is a hexa EF-hand Ca(2+)-binding protein expressed in neuroendocrine, pancreatic endocrine and retinal cells. The protein has been noted for its expression in specific neuronal subtypes in the support of hierarchical organizing principles in the mammalian brain. Secretagogin has previously been found to interact with SNAP25 involved in Ca(2+)-induced exocytosis. Here, the cellular int
