Rhodopsin Protein, Bovine, Recombinant (His & KSI)

Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change that activates signaling via G-proteins. Subsequent receptor phosphorylation mediates displacement of the bound G-protein alpha subunit by the arrestin SAG and terminates signaling. Rhodopsin Protein, Bovine, Recombinant (His & KSI) is expressed in E. coli expression system with N-6xHis-KSI tag. The predicted molecular weight is 19.5 kDa and the accession number is P02699.
