Predicted to enable several functions, including PDZ domain binding activity; lipopolysaccharide binding activity; and phosphatidylserine binding activity. Involved in postsynaptic actin cytoskeleton organization and regulation of synapse assembly. Is active in glutamatergic synapse. Is integral component of postsynaptic membrane. Human ortholog(s) of this gene implicated in glioblastoma. Orthologous to human ADGRB1 (adhesion G protein-coupled receptor B1). [provided by Alliance of Genome Resources, Apr 2022]
