Predicted to enable G protein-coupled receptor activity. Predicted to be involved in several processes, including G protein-coupled receptor signaling pathway; positive regulation of Rho protein signal transduction; and response to acidic pH. Predicted to act upstream of or within G protein-coupled receptor signaling pathway; blood vessel development; and negative regulation of angiogenesis. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Orthologous to human GPR4 (G protein-coupled receptor 4). [provided by Alliance of Genome Resources, Apr 2022]
