Predicted to enable G protein-coupled receptor activity. Predicted to be involved in positive regulation of Rho protein signal transduction and positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G protein-coupled signaling pathway. Predicted to act upstream of or within T cell differentiation; negative regulation of leukocyte chemotaxis; and negative regulation of tumor necrosis factor production. Predicted to be located in cytoplasmic vesicle membrane. Predicted to be integral component of plasma membrane. Orthologous to human GPR18 (G protein-coupled receptor 18).
