GPR21 has several biochemical functions, for example, G-protein coupled amine receptor activity, G-protein coupled receptor activity, signal transducer activity. Some of the functions are cooperated with other proteins, some of the functions could acted by GPR21 itself. We selected most functions GPR21 had, and list some proteins which have the same functions with GPR21. You can find most of the proteins on our site.
