Predicted to enable G protein-coupled receptor activity; G-protein alpha-subunit binding activity; and G-protein beta-subunit binding activity. Involved in positive regulation of glomerular filtration. Acts upstream of or within with a positive effect on vasodilation. Predicted to be located in early endosome; plasma membrane; and pseudopodium. Predicted to be integral component of plasma membrane. Biomarker of lung disease. Human ortholog(s) of this gene implicated in asthma; chronic obstructive pulmonary disease; and respiratory allergy. Orthologous to human F2RL1 (F2R like trypsin receptor 1).
