Ptgdr2 Gene Summary [Mouse]
Enables prostaglandin D receptor activity; prostaglandin F receptor activity; and prostaglandin J receptor activity. Acts upstream of or within several processes, including adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway; calcium-mediated signaling; and negative regulation of male germ cell proliferation. Predicted to be active in neuron projection and plasma membrane. Human ortholog(s) of this gene implicated in asthma. Orthologous to human PTGDR2 (prostaglandin D2 receptor 2).

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 mouse Ptgdr2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
