SNED1 is a human protein expressed at low levels in a wide range of tissues. The protein is soluble and found in circulating blood and the conceptually translated protein has four domains of interest. These domains include a nidgen (NIDO) domain, three fibronectin type III (FN3) domains, several calcium binding EGF-like domains (EGF CA), and one complement control protein (CCP) domain. The gene is found on chromosome 2, locus q37.3. The mRNA was isolated from the spleen and is 6834bp in length. The conceptually translated protein is 1178aa long. This protein is predicted to interact with somatostatin, spermidine synthase and TMEM132C.
