Dpp4 Gene Summary [Rat]
Enables several functions, including collagen binding activity; dipeptidyl-peptidase activity; and identical protein binding activity. Involved in B-1a B cell differentiation; protein catabolic process; and regulation of lymphocyte mediated immunity. Located in cell surface. Human ortholog(s) of this gene implicated in Middle East respiratory syndrome and type 2 diabetes mellitus. Orthologous to human DPP4 (dipeptidyl peptidase 4).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Dpp4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
