MKL1 Antibody – Rabbit Polyclonal

MKL1: Transcriptional coactivator of serum response factor (SRF) with the potential to modulate SRF target genes. Suppresses TNF-induced cell death by inhibiting activation of caspases; its transcriptional activity is indispensable for the antiapoptotic function. It may up-regulate antiapoptotic molecules, which in turn inhibit caspase activation. Forms with SCAI and SRF a nuclear ternary complex which binds the CArG consensus motif (CArG box) on DNA via SRF. Interacts with ACTB; interaction with ACTB prevents interaction with SCAI. Interacts with MKL2. Ubiquitously expressed, has been detected in lung, placenta, small intestine, liver, kidney, spleen, thymus, colon, muscle, heart and brain.
