Isoelectric Focusing to Quantify Rhodopsin Phosphorylation in Mouse Retina [PDF]
Rhodopsin is a G-protein coupled receptor (GPCR) that mediates vision under dim light. Upon light exposure, rhodopsin is phosphorylated at multiple serine and threonine sites at its carboxyl-terminus by rhodopsin kinase (GRK1). This, in turn, reduces its
