  • Subunit: Heterodimer of an alpha and a beta chain (By similarity). Interacts with HRG (via the HRR domain); the interaction contributes to the antiangiogenic properties of the histidine/proline-rich region (HRR) of HRG (By similarity) Mass spectrometry: Mass=32875.93; Method=MALDI; Range=1-284 (P09493-3); Source=PubMed:11840567;
  • Tissue specificity: Detected in primary breast cancer tissues but undetectable in normal breast tissues in Sudanese patients. Isoform 1 is expressed in adult and fetal skeletal muscle and cardiac tissues, with higher expression levels in the cardiac tissues. Isoform 10 is ex
  • Function:
    UniProtKB/Swiss-Prot Summary: TPM1_HUMAN, P09493 Function: Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments
  • Similarity:
    Belongs to the tropomyosin family [IMAGE]

    Disorder & Mutation    
    Source Disease
    SWISS-PROTCardiomyopathy, familial hypertrophic 3 (CMH3) [MIM:115196]: A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. Note=The disease is caused by mutations affecting the gene represented in this entry
    SWISS-PROTCardiomyopathy, dilated 1Y (CMD1Y) [MIM:611878]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Note=The disease is caused by mutations affecting the gene represented in this entry
    SWISS-PROTLeft ventricular non-compaction 9 (LVNC9) [MIM:611878]: A disease due to an arrest of myocardial morphogenesis. It is characterized by a hypertrophic left ventricle with deep trabeculations and with poor systolic function, with or without associated left ventricular dilation. In some cases, it is associated with other congenital heart anomalies. Note=The disease is caused by mutations affecting the gene represented in this entry
