Rhodopsin lateral diffusion as a function of rod outer segment disk membrane axial position.

PMCID: PMC1434906  PMID: 6722271

Abstract

Rhodopsin lateral diffusion was measured at three points along the axis of frog outer segments using the method of absorbance recovery after photobleaching. Mean recovery times were slightly longer in distal disk membranes than in proximal disks. A small reduction of pigment mobility with disk age may reflect subtle changes in membrane composition.
