Target

  • 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. Binds calcium.

  • Tissue specificity

    Detected in cardiac tissue and platelets, the form found in cardiac tissue is a higher molecular weight than the form found in platelets. Expressed at higher levels in the platelets of hypertensive patients with cardiac hypertrophy than in the platelets of hypertensive patients without cardiac hypertrophy (at protein level).

  • Sequence similarities

    Belongs to the tropomyosin family.

  • Domain

    The molecule is in a coiled coil structure that is formed by 2 polypeptide chains. The sequence exhibits a prominent seven-residues periodicity.

  • Cellular localization

    Cytoplasm > cytoskeleton.

     ab181085 Anti-TPM4 antibody [EPR13316] was shown to specifically react with TPM4 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266606 (knockout cell lysate ab257758) was used.  Wild-type and TPM4 knockout samples were subjected to SDS-PAGE.  ab181085 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at room temperature for 2. 5 hours at 1 in 1000 dilution and 1 in 20000 dilution respectively.  Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
