Predicted to enable G protein-coupled receptor activity. Acts upstream of or within glial cell development; regulation of oligodendrocyte progenitor proliferation; and swimming behavior. Predicted to be located in membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including heart; liver; nervous system; pleuroperitoneal region; and trigeminal placode. Human ortholog(s) of this gene implicated in bilateral frontoparietal polymicrogyria and bilateral perisylvian polymicrogyria. Orthologous to human ADGRG1 (adhesion G protein-coupled receptor G1).
