摘要
Cardiomyopathy-related mutations in human cardiac troponin subunits, including troponin C (hcTnC), troponin I (hcTnI), and troponin T (hcTnT), are well-documented. Recently, it has been recognised that human cardiac troponin (hcTn) is a sophisticated allosteric system. Therefore, the effect of drugs on this protein complex should be studied with assembled hcTn rather than a short fragment of a subunit or the subunit itself. Here, we describe the expression and assembly of active hcTn in Escherichia coli, a novel method that is rapid and simple, and produces large amounts of functional hcTn. (C) 2012 Elsevier Inc.
