Primary structure of mouse secretogranin III and its absence from deficient mice
Abstract
The rat brain- and pituitary-specific 1B1075 mRNA encodes a chromogranin/secretogranin-like protein, called secretogranin III (SgIII), that is a component of intracellular dense core vesicles. In order to study the function of this gene product in a mouse model system, we have isolated the murine homolog of the rat 1B1075 mRNA. This mRNA contains 2163 bp encoding a putative protein of 421 amino acids. Cleavage of the strong putative signal sequence would yield a mature protein of 51 kDa. The sequence of the encoded murine protein preserves the structural features that suggest SgIII is a member of the granin family, and allowed us to recognize and correct errors in our published rat sequence.
