Troponin, working in conjunction with tropomyosin, functions as a molecular switch, regulating muscle contraction in response to changes in the intracellular Ca2+ concentration. Troponin consists of three subunits, the Ca2+-binding subunit troponin C (TnC), the tropomyosin-binding subunit troponin T (TnT), and the inhibitory subunit troponin I (TnI). Troponin I binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place, because of which myosin cannot bind to actin in relaxed muscle. When Calcium binds to the Troponin C it causes certain confomational changes which leads to dislocation of troponin I. The letter “I” is given due to its inhibitory character. Tissue-specific Troponin Subtypes: Slow-twitch skeletal muscle isoform troponin I, TNNI1 (1q31.3, 191042) Fast-twitch skeletal muscle isoform troponin I, TNNI2 (11p15.5, 191043) Cardiac troponin I, TNNI3 (19q13.4, 191044) Applications: Suitable for use in ELISA. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: For long-term storage, store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. CAS Number: 77108-40-8 |
