Reg1B: Products
The Reg family constitutes a subset of the calcium-dependent C-type lectin superfamily. These small, secreted proteins have been implicated in a range of physiological processes including acting as acute phase reactants, lectins, survival/growth factors for insulin-producing pancreatic beta-cells, neural cells, and epithelial cells of the digestive system. Studies also indicate a role for Reg family members in tumor formation and indicate their potential for use as biomarkers of carcinogenesis.
Reg1B, also known as secretory pancreatic stone protein 2 and lithostathine 1 beta, is a type I subclass member of the Reg family of secreted proteins and contains a C-type lectin domain. Reg1B is closely related to Reg1A, a protein that is implicated in islet cell regeneration and diabetogenesis.
