| pubmed-article:2777792 | pubmed:abstractText | Monoclonal antibodies identify two distinct isoforms of troponin I in rat cardiac muscle, one predominant in the embryonic and fetal heart and one predominant in the adult heart. The two isoforms can be resolved by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, with apparent molecular weights of 27,000 and 31,500, respectively. The adult isoform is specifically recognized by a monoclonal antibody that is unreactive with the embryonic variant, while two other monoclonal antibodies recognize both isoforms. A monoclonal antibody to cardiac troponin T was used to isolate by affinity chromatography the troponin complex from adult and neonatal rat heart. Affinity purified troponin from neonatal heart was found to contain both the embryonic and adult isoforms of troponin I. Comparative immunoblotting analysis with different muscle tissues shows that embryonic troponin I is identical with respect to electrophoretic mobility and pattern of immunoreactivity to the major troponin I isoform found in adult slow skeletal muscle. Troponin I switching may be implicated in developmental changes involving Ca2+ and pH sensitivity of the contractile system and response to beta-adrenergic stimulation. | lld:pubmed |
