BTC / Betacellulin蛋白背景综述

Probetacellulin, also known as Betacellulin and BTC is a single-pass type I  membrane protein. Betacellulin is synthesized in several tissues and tumor cells. It is predominantly expressed in pancreas and small intestine. The expression of Betacellulin is particularly high in the pancreas where it is thought to play a role in the differentiation of pancreatic beta cells. Betacellulin belongs to the epidermal growth factor (EGF) family of peptide ligands that are characterised by a six-cysteine consensus motif that forms three intra-molecular disulfide bonds crucial for binding the ErbB receptor family. Betacellulin was initially described, purified and cloned from a mouse insulinoma cell line. It is proteolytically processed from a larger membrane-anchored precursor and is a potent mitogen for a wide variety of cell types. Betacellulin binds and activates ErbB-1 and ErbB-4 homodimers. Betacellulin stimulated gastrointestinal growth, the increased responsiveness of the terminal ileum and colon suggesting therapeutic potential in disease conditions in which ileal or colonic re-growth is desirable. Betacellulin further stimulated a diuresis suggesting an additional role in fluid homeostasis.
