Fig. 4. The carboxyl terminus of both CAP and MCH1 binds actin. A, full-length MCH1 and CAP bind actin. Lysates from cap cells (SKN50) expressing either Myc-tagged CAP or Myc-tagged MCH1 were subjected to immunoprecipitation with anti-Myc antibody (9E10). Specific protein interactions were blocked by the addition of excess Myc peptide (50 µg). Immune complexes were resolved on SDS-acylamide gels and transferred to nylon membranes. Immunoblots were probed with an anti-actin monoclonal antibody (20 µg/ml) (Boehringer Mannheim). B, the carboxyl-terminal domain of CAP and MCH1 binds actin. Lysates from cap cells expressing various Myc-tagged domains of CAP, or the carboxyl-terminal of MCH1, were subjected to immunoprecipitation. Immunoblots were incubated with an anti-actin monoclonal antibody (20 µg/ml). Antigen detection was performed by ECL chemiluminescent assay.
