Description:
Betacellulin, a member of the epidermal growth factor family, has been identified in the conditioned medium of cell lines derived from mouse pancreatic beta cell tumors. Betacellulin is a 32-kilodalton glycoprotein that appears to be processed from a larger transmembrane precursor by proteolytic cleavage. The carboxyl-terminal domain of betacellulin has 50 percent sequence similarity with that of rat transforming growth factor alpha. Betacellulin is a potent mitogen for retinal pigment epithelial cells and vascular smooth muscle cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shing, Y -- Christofori, G -- Hanahan, D -- Ono, Y -- Sasada, R -- Igarashi, K -- Folkman, J -- CA 70118/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1993 Mar 12;259(5101):1604-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Surgery, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8456283" target="_blank"〉PubMed〈/a〉
