Anti-CSRP3 antibody [EPR12615(B)] - BSA and Azide free,Abcam,AB249730

Target data Positive regulator of myogenesis. Acts as a cofactor for myogenic bHLH transcription factors such as MYOD1, and probably MYOG and MYF6. Enhances the DNA-binding activity of the MYOD1 : TCF3 isoform E47 complex and may promote formation of a functional MYOD1 : TCF3 isoform E47 : MEF2A complex involved in myogenesis (By similarity). Plays a crucial and specific role in the organization of cytosolic structures in cardiomyocytes. Could play a role in mechanical stretch sensing. May be a scaffold protein that promotes the assembly of interacting proteins at Z-line structures. It is essential for calcineurin anchorage to the Z line. Required for stress-induced calcineurin-NFAT activation (By similarity). The role in regulation of cytoskeleton dynamics by association with CFL2 is reported conflictingly : Shown to enhance CFL2-mediated F-actin depolymerization dependent on the CSRP3 : CFL2 molecular ratio, and also shown to reduce the ability of CLF1 and CFL2 to enhance actin depolymerization (PubMed : 19752190, PubMed : 24934443). Proposed to contribute to the maintenance of muscle cell integrity through an actin-based mechanism. Can directly bind to actin filaments, cross-link actin filaments into bundles without polarity selectivity and protect them from dilution- and cofilin-mediated depolymerization; the function seems to involve its self-association (PubMed : 24934443). In vitro can inhibit PKC/PRKCA activity (PubMed : 27353086). Proposed to be involved in cardiac stress signaling by down-regulating excessive PKC/PRKCA signaling (By similarity).. Isoform 2. May play a role in early sarcomere organization. Overexpression in myotubes negatively regulates myotube differentiation. By association with isoform 1 and thus changing the CSRP3 isoform 1 : CFL2 stoichiometry is proposed to down-regulate CFL2-mediated F-actin depolymerization. See full target information CSRP3
