B-adrenergički-receptor kinaza
B-adrenergički-receptor kinaza (EC 2.7.11.15, ATP:beta-adrenergički-receptor fosfotransferaza, beta-adrenergički receptor-specifična kinaza, beta-AR kinaza, beta-ARK, beta-ARK 1, beta-ARK 2, beta-receptor kinaza, GRK2, GRK3, beta-adrenergički-receptor kinaza (fosforilacija), beta2ARK, betaARK1, beta-adrenoceptor kinaza, beta-adrenoceptor kinaza 1, beta-adrenoceptor kinaza 2, ADRBK1, BARK1, adrenergički receptor kinaza, STK15) je enzim sa sistematskim imenom ATP:(beta-adrenergic receptor) fosfotransferaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- ATP + [beta-adrenergički receptor] ADP + fosfo-[beta-adrenergički receptor]
G-protein je neophodan za aktivaciju i stoga ovaj enzim pripada familiji G-protein-zavisnih receptorskih kinaza (GRKs).
