Peripherin/RDS is a member of the tetraspanin family of integral membrane proteins and plays a major role in the morphology of photoreceptor outer segments. Peripherin/RDS has a long extracellular loop (hereafter referred to as the LEL domain), which is vital for its function. Point mutations in the LEL domain often lead to impaired photoreceptor formation and function, making peripherin/RDS an important drug target.

Rab11-FIP3 is an endosomal recycling compartment (ERC) protein that is implicated in the process of membrane delivery from the ERC to sites of membrane insertion during cell division. Here we report that Rab11-FIP3 is critical for the structural integrity of the ERC during interphase. We demonstrate that knockdown of Rab11-FIP3 and expression of a mutant of Rab11-FIP3 that is Rab11-binding deficient cause loss of all ERC-marker protein staining from the pericentrosomal region of A431 cells.
