- Recently, a novel gene family has been identified and characterized, the protein products of which are localized in the endoplasmic reticulum. The proteins encoded by these genes were therefore named Reticulons. Reticulon-1 (Rtn-1) was formerly designated NSP (Neuroendocrine-Specific-Protein), because it is specifically expressed in neural and neuroendocrine tissues. The NSP-gene has been mapped by fluorescence in situ hybridization to human chromosome 14q21-q22. The NSP-gene encodes three overlapping proteins, i.e. NSP-A, NSP-B, and NSP-C. These proteins were found to be anchored to membranes of the endoplasmic reticulum through their common carboxy-terminal regions.NSP-A is a protein with a molecular weight (MW) of about 135kD, which occurs in various isoforms presumably depending on the degree of phosphorylation in serine residues. In lung cancer diagnosis NSP-A appeared to be a reliable marker for the detection of neuroendocrine differentiation, since most of the small cell lung carcinoma (SCLC) and carcinoid tumors showed expression of NSP-A. NSP-B is a phosphoprotein with a MW of 45kD and is restricted to the lung cancer cell line NCI-H82. NSP-B is not found for so far in human tissues. NSP-C is a protein with a MW of 23kD which is not phosphorylated and is found with NSP-A in SCLC (cell lines) and not in non-SCLC (cell cultures).
