p-MII:SAG dissociates to p-RHO and SAG

Loss of all-trans-retinal (atRAL) is followed by dissociation of arrestin (SAG) from p-RHO. RHO is then available for covalent binding to 11-cis-retinal (11cRAL), supplied by the retinal pigment epithelium, to regenerate rhodopsin. SAG is capable of binding weakly to rhodopsin, so the dissociation in some rhodopsins may occur after regeneration (Baumann & Bender 1973).

全反式视黄醛（atRAL）的丧失导致逮捕素（SAG）与p-RHO的解离。随后，RHO得以与由视网膜色素上皮提供的11-顺式视黄醛（11cRAL）共价结合，以再生视紫红质。SAG能够与视紫红质弱结合，因此在某些视紫红质的再生过程中，逮捕素可能发生解离（Baumann & Bender 1973）。
