產品詳情

  • 產品描述：
    大鼠肌鈣蛋白I，骨骼肌慢肌(TNNI1)酶聯免疫試劑盒（CSB-EL024011RA）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的TNNI1含量。TNNI1是心肌肌鈣蛋白I的慢骨骼肌亞型，主要表達于慢肌纖維。作為心肌重要調節蛋白，它參與肌肉收縮舒張的調控。當前研究聚焦其在心肌病等疾病中表達變化及機制，以探索其作為潛在診斷標志物和治療靶點的可能。試劑盒檢測范圍為15.6 pg/mL-1000 pg/mL，本試劑盒適用于多種科研場景，如骨骼肌損傷模型的生物標志物分析、肌肉代謝相關研究、運動醫學中肌纖維類型轉換機制探索，以及藥理學實驗中藥物對慢肌功能影響的評估。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Troponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
  • 基因功能參考文獻：
    1. these results suggest that cTnI(R146G) and cTnI(R21C) blunt PKA modulation of activation and relaxation kinetics by prohibiting cardiac-specific N-terminal interaction with the cTnI inhibitory peptide. PMID: 26391394
    2. troponin I phosphorylation has a role in protein kinase C-mediated enhanced contractile performance of myocytes PMID: 12815045
    3. A novel role is described for cardiac TnI PKA phosphorylation in the rate-dependent enhancement of systolic & diastolic function in vivo & afterload sensitivity of relaxation. This has implications for cardiac failure. PMID: 14726477
    4. MuRF1 functions as a ubiquitin ligase to catalyze ubiquitylation of troponin I through a RING finger-dependent mechanism PMID: 15601779
    5. TnI-isoform and titin-isoform switching and corresponding functional changes during heart development are not initiated by birth but are genetically programmed PMID: 16679402
    6. The goal here was to identify domain clusters and residues that confer troponin I isoform-specific myofilament Ca2+ and pH sensitivities of contraction. PMID: 17602701
    7. This study highlights cellular contractile defects by cardiomyopathy mutant cTnIs that are allele and species dependent. PMID: 18423659
    8. Study identifies tyrosine phosphorylation as a novel protein kinase Cdelta (PKCdelta) activation mechanism that modifies PKCdelta-dependent phosphorylation of cardiac troponin I. PMID: 18550549
    9. The negative inotropic effect of HIV gp120 is mediated by a novel signaling pathway that begins with binding to a cardiac myocyte CXCR4 receptor, followed by phosphorylation of both p38 MAP kinase and Troponin I. PMID: 18850076
    10. observed higher relative level of natural antisense RNA in neonatal cardiac fibroblasts compared to neonatal cardiomyocytes, pointing to a cell type-specific expression of sense and antisense RNA PMID: 19184367
    11. These findings suggest that altered TnI function, due to changes in the distribution of phosphorylated sites, is an early contributor to reduced contractility of the heart. PMID: 19507043
