Secretagogin is a Ca2+-binding protein specifying subpopulations of telencephalic neurons

Proceedings of the National Academy of Sciences of the United States of America

The Ca(2+)-binding proteins (CBPs) parvalbumin, calbindin, and calretinin are phenotypic markers of terminally differentiated neurons in the adult brain. Although subtle phylogenetic variations in the neuronal distribution of these CBPs may occur, morphologically and functionally diverse subclasses of interneurons harbor these proteins in olfactory and corticolimbic areas. Secretagogin (scgn) is a recently cloned CBP from pancreatic beta and neuroendocrine cells. We hypothesized that scgn is…
