Fig. 2. Mupp1 immunoprecipitation (IP) co-precipitates Crb1, Mpp4 and Pals1. Crb1 was co-immunoprecipitated from retinal lysates of wild-type but not Crb1-/- mice. Patj was not found in the precipitated protein complex but was present only in the total retinal lysate (L). Anti-Pals1 detected a Pals1 doublet (Roh et al., 2002). In the control (Pre), mouse IgGs were used for immunoprecipitation.
