FUNCTION: This gene encodes a member of the granin family of acidic secretory glycoproteins that are expressed in endocrine cells and neurons. The encoded preproprotein undergoes proteolytic processing to generate multiple functions peptides including pancreastatin, catestatin and serpinin. The encoded protein plays important roles in the neuroendocrine system including regulated secretion of peptide hormones and neurotransmitters. Mice lacking the encoded protein exhibit elevated blood pressure which can be rescued by transgenic expression of the human ortholog. [provided by RefSeq, Nov 2015]
PHENOTYPE: Homozygotes and heterozygotes for one allele display hypertension, abnormal plasma and adrenal adrenaline and noradrenaline levels and, in homozygotes, partial embryonic lethality. Homozygotes for a second allele only have elevated urinary adrenaline, noradrenaline and dopamine levels. [provided by MGI curators]
