{"product_id":"rq5557","title":"TNNT3 Antibody","description":"\u003cp\u003eFast skeletal muscle troponin T (fTnT) is a protein that in humans is encoded by the TNNT3 gene. It is mapped to 11p15.5. The binding of Ca(2+) to the trimeric troponin complex initiates the process of muscle contraction. Increased Ca(2+) concentrations produce a conformational change in the troponin complex that is transmitted to tropomyosin dimers situated along actin filaments. The altered conformation permits increased interaction between a myosin head and an actin filament which, ultimately, produces a muscle contraction. The troponin complex has protein subunits C, I, and T. Subunit C binds Ca(2+) and subunit I binds to actin and inhibits actin-myosin interaction. Subunit T binds the troponin complex to the tropomyosin complex and is also required for Ca(2+)-mediated activation of actomyosin ATPase activity. There are 3 different troponin T genes that encode tissue-specific isoforms of subunit T for fast skeletal-, slow skeletal-, and cardiac-muscle. This gene encodes fast skeletal troponin T protein; also known as troponin T type 3. Alternative splicing results in multiple transcript variants encoding additional distinct troponin T type 3 isoforms. A developmentally regulated switch between fetal\/neonatal and adult troponin T type 3 isoforms occurs. Additional splice variants have been described but their biological validity has not been established. Mutations in this gene may cause distal arthrogryposis multiplex congenita type 2B (DA2B).\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Rabbit","offer_id":49475963584792,"sku":"RQ5557","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_8073ac98-d6e3-43b5-8ec0-d5ef74a29c88.jpg?v=1734464583","url":"https:\/\/danabiosci.com\/products\/rq5557","provider":"Dana Bioscience","version":"1.0","type":"link"}
