RGS4
Regulator G proteinske signalizacije 4 (RGS4) je protein koji reguliše G proteinsku signalizaciju.[1] Brojne sudije su ukazale na vezu RGS4 gena sa šizofrenijom,[2][3][4][5] mada postoje i studije koje nisu ustanovile vezu.[6]

RGS4 je takođe od interesa kao jedan od tri glavna RGS proteina (zajedno sa RGS9 i RGS17) koji učestvuju u terminaciji signalizacije mi opioidnog receptora,[7] i moguće je da je značajan u razvoju tolerancije na opioidne lekove.[8][9][10][11][12]

Interakcije уреди
Za RGS4 je pokazano da interaguje sa ERBB3,[15] GNAQ[16][17] i COPB2.[18]
