Ups1p and Ups2p affect interactions between the TIM23 translocase and PAM proteins. (A and B) Mitochondria were solubilized with digitonin and subjected to immunoprecipitation with anti-Flag M2-agarose. The mitochondrial lysate (Load; 15%) and bound proteins (Elute; 100%) are shown. Proteins were analyzed by immunoblotting using the indicated antibodies. The asterisk indicates a nonspecific band. Band intensity was normalized relative to that detected in wild-type (WT) mitochondria in B. Values are mean ± SEM (n = 4). (C and D) Immunoprecipitation was performed as described in A using mitochondria expressing Pam16p-Flag. Quantitation of band intensity is shown in D. (E and F) Immunoprecipitation was performed as described in A using mitochondria expressing Tim22p-Flag. (D and F) Values are mean ± SEM (n = 3). co-ip, coimmunoprecipitation.
