independently of GPCR activation upon acquiring mutations that prevent GTPase activity and result in constitutive inhibited by YM, demonstrating that resistance to YM inhibition by membrane-binding mutants is specific to constitutively

Constitutive Activity of the viral CKR US28 and “Chemokine Scavenger” ACKR3 Both US28 and ACKR3 are constitutively US28 evolved high constitutive activity to evade host immunity, whereas ACKR3 functions as a homeostatic chemokine "scavenger" by downregulating extracellular chemokine gradients through constitutive internalization Experimental 3D structures of both receptors reveal that they employ distinct mechanisms for constitutive In ACKR3, the presence of a tyrosine at position 6.40 plays a role in its constitutive activity (Yen,
