Explanation by: Admin

Golf is a G-protein that plays a key role in the regulation of vision. It is specifically involved in the phototransduction process in the retina of the eye, where it helps to convert light signals into electrical signals, allowing vision.

Why other options are incorrect:

  • (B) Gi family – This G-protein is involved in inhibitory signaling pathways but not in vision regulation.
  • (C) Gs family – This G-protein typically activates adenylate cyclase and is involved in various signaling pathways, not in vision regulation.
  • (D) Gq family – This G-protein is involved in signaling pathways that typically increase intracellular calcium but does not directly regulate vision.
