Ptafr Gene Summary [Rat]
Enables mitogen-activated protein kinase binding activity. Involved in several processes, including positive regulation of biosynthetic process; positive regulation of transport; and regulation of cellular extravasation. Predicted to be located in plasma membrane. Used to study several diseases, including acute kidney failure; neutropenia; perinatal necrotizing enterocolitis; pleurisy; and transient cerebral ischemia. Biomarker of conjunctivitis; sciatic neuropathy; and transient cerebral ischemia. Orthologous to human PTAFR (platelet activating factor receptor).

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 Ptafr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
