Function

Interact with proteins implicated in rhodopsin trafficking (NEK2 and NINL). Rrecruitment of several proteins to centriole proximal ends, including Girdin (Girders of actin filaments) and proteins that associate with the distal region of the mother centriole (NEK2, ninein, CEP170, p150glued and KIF2A) (30421101). C- P1 anchores rootletin filaments that hold duplicated centrosomes together(28100636). Mutations are associated to Usher Syndrome and retinitis pigmentosa (28005958).
