title: Immunoreactivities of m-calpain, calpastatin, nitric oxide synthase, myelin basic protein and dynamin II in baker's yeast, wheat germ and lobster tail muscle.
abstract: Vertebrate m-calpain, calpastatin, constitutive nitric oxide synthase, myelin basic protein, and dynamin I are substrates of protein kinase C (PKC). The presence/absence of similar/related protein in nonvertebrate was investigated by immunological methods, including (1) affinity chromatography on agarose-secondary antibodies and agarose IgG for removal of nonspecific immunoreactivities from crude extracts; (2) omitting beta-mercaptoethanol treatment and boiling prior to SDS-PAGE to increase the immunoreactivity; (3) immunoreactivity comparisons of nonspecific IgG as controls with specific anti-(vertebrate PKC-substrates/related proteins) in Western blots. It was found that (a) m-calpain and dynamin I were absent in baker's yeast, wheat germ and lobster tail muscle, (b) m-calpain, nitric oxide synthase, myelin basic protein and dynamin II were present in all three samples, and (c) calpastatin was present in baker's yeast and lobster tail muscle. The presence and absence of these proteins suggest evolutionary conservation and divergence, respectively, of these PKC substrates.
