How is rhodopsin regulated
WebThe first step in the quenching of R* activity is the phosphorylation of its C-terminus by rhodopsin kinase, a process that is believed to be regulated in a Ca2+ -dependent … WebLike other GPCRs, the activity of rhodopsin is regulated by phosphorylation and the binding of arrestin. In the current investigation, we have explored by modeling methods the interaction of rhodopsin and arrestin under the assumption that either one or two rhodopsin molecules bind each arrestin molecule.
