Human Polyclonal TNNI1 Primary Antibody for IHC, WB - ABIN2777151
Ralli, Horwich, Fonarow: Relationship between anemia, cardiac troponin I, and B-type natriuretic peptide levels and mortality in patients with advanced heart failure. in American heart journal 2005
TNNI3K (show TNNI3K Antibodies) is a cardiac-specific gene, encoding a cardiac troponin I (show TNNI3 Antibodies)-interacting MAP kinase (show MAPK1 Antibodies). In mice, Tnni3k (show TNNI3K Antibodies) is shown to play an important role in the regulation of cardiac differentiation and cardiac contractility
Data suggest that mutation A162H in switch region of troponin I induces transitory curved conformation and promotes contraction of troponin I bound to regulatory domain of troponin C; this is countered by residue E164 to ensure proper relaxation.
Elevations of troponin I and N-terminal pro-B-type natriuretic peptide (show BNP Antibodies) (NT-proBNP) are common in patients with atrial fibrillation and independently related to increased risks of stroke and mortality.
Elevated post-operative troponin 1 levels predict long-term mortality in older patients undergoing emergency orthpedic surgery.
troponin I phosphorylation has a role in protein kinase C (show PKC Antibodies)-mediated enhanced contractile performance of myocytes
MEF2 (show MEF2A Antibodies) activation of the troponin I slow enhancer is repressed by hMusTRD1alpha1 (show GTF2IRD1 Antibodies)
Low expression of ssTnI was found in 60% of patients in sinus rhythm or paroxysmal AF and in 8% of patients with chronic AF. Relative ssTnI mRNA expression was significantly lower in patients with AF than in those in sinus rhythm.
A biological marker of myocardial injury, but may also be increased after a grand mal (show MAL Antibodies) seizure.
These results suggest that this R21C mutation in TnI affects the Ca(2+)-sensitizing effect of Tn, the ability of TnI to be readily phosphorylated by PKA and the stability of TnI to calpain.
Relationship between myocardial injury, assessed by cardiac troponin I (cTnI) levels, and outcome in selected critically ill patients without acute coronary syndromes or cardiac dysfunction
analysis of expression profiling of porcine troponin I family in three different types of muscles during development
Two novel single nucleotide polymorphisms (EU743939:g.5174T>C in intron 4 and EU743939:g.8350C>A in intron 7) in TNNI1 and one SNP (EU696779:g.1167C>T in intron 3) in TNNI2 (show TNNI2 Antibodies) were identified.
data demonstrate that thyroid hormone (show PTH Antibodies) can alter the time course of ssTnI gene expression in cultured cardiac myocytes and TnI (show TNNI2 Antibodies) gene regulation is also controlled by some unknown programmed events inside of cardiac myocytes
a localized N-terminal region of TnI comprised of amino acids 33-80, which interacts with C-terminal regions of cTnC and cTnT, is of particular significance in transducing signaling of thin filament activation by strong cross-bridges
K+-depolarization increased Tnni1 and Acta1 (show ACTA1 Antibodies) mRNA levels in both differentiated C2C12 and rat skeletal muscle cells in primary culture
the up-stream domain ( approximately 1,800 bp) of mouse fetal TnI (show TNNI2 Antibodies) gene is been cloned and characterized
Phosphorylation of troponin I was significantly reduced in Galphaq (show GNAQ Antibodies)-overexpressing mice compared to wild type.
Troponin proteins associate with tropomyosin and regulate the calcium sensitivity of the myofibril contractile apparatus of striated muscles. Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory subunit\; blocking actin-myosin interactions and thereby mediating striated muscle relaxation. The TnI subfamily contains three genes: TnI-skeletal-fast-twitch, TnI-skeletal-slow-twitch, and TnI-cardiac. The TnI-fast and TnI-slow genes are expressed in fast-twitch and slow-twitch skeletal muscle fibers, respectively, while the TnI-cardiac gene is expressed exclusively in cardiac muscle tissue. This gene encodes the Troponin-I-skeletal-slow-twitch protein. This gene is expressed in cardiac and skeletal muscle during early development but is restricted to slow-twitch skeletal muscle fibers in adults. The encoded protein prevents muscle contraction by inhibiting calcium-mediated conformational changes in actin-myosin complexes.
