CKRs can be classified into typical CKRs, atypical CKRs (ACKRs) which lack G-protein signaling, and viral It has been demonstrated that the shorter truncation variant, CCL15L, exhibits bias toward G-protein signaling interaction with a specific side chain can dictate whether an agonist exhibits a bias toward G-protein signaling Chemokine Scavenger” ACKR3 Both US28 and ACKR3 are constitutively active receptors, meaning they can signal
