Enables protein kinase binding activity. Involved in several processes, including positive regulation of macromolecule metabolic process; positive regulation of neuron differentiation; and positive regulation of signal transduction. Acts upstream of or within several processes, including glucose homeostasis; positive regulation of neuron projection development; and positive regulation of protein kinase activity. Located in cell surface; membrane raft; and plasma membrane. Is expressed in several structures, including alimentary system; brain; brown fat; extraembryonic component; and genitourinary system. Orthologous to human GPRC5B (G protein-coupled receptor class C group 5 member B). [provided by Alliance of Genome Resources, Apr 2022]
