Immunological identification and sequence characterization of a peptide derived from the processing of neuroendocrine protein 7B2

FEBS Lett. 1991 Dec 2;294(1-2):23-6. doi: 10.1016/0014-5793(91)81334-5.

Abstract

A newly raised antiserum against the C-terminal region of neuroendocrine protein 7B2 was used to purify a novel peptide from the culture media of the mouse corticotroph cell line AtT-20. Based on partial sequencing, this peptide, which we call Cter-7B2, begins at Ser156 and appears to result from the cleavage of pro7B2 after a five-basic-residue sequence. Thus, 7B2 processing may contribute to the diversity of peptides found in neuronal and endocrine cells.
