Figure 3. Co-immunoprecipitation of MutLα.
MLH1 was precipitated from extracts with an antibody binding the N-terminus of MLH1 as detailed in Materials and Methods. The amount of co-precipitated PMS2 was determined in relation to wild-type (100%) (average; standard deviation when more than one experiment was performed): Gln542Leu (54; 26); Asn551Thr (87; 7); Leu559Arg (68; 25); Ala586Pro (17; 16); Asp601Gly (112; 7); Lys618Ala (109; 3); Leu622His (73; 8); Leu636Pro (78; 1); Pro648Leu (68); Pro654Leu (51); Arg659Leu (77); Arg659Gln (126); Thr662Pro (24); Glu663Gly (96); Leu749Pro (30; 24); Tyr750X (23;33); Arg755Ser (134;9); Arg755Trp (82; 37). One variant (p.Arg659Pro) was omitted from the analysis due to low expression.
