Function Smooth muscle cells (SM) and cardiac muscle cells- specific transcriptional factor which uses the canonical single or multiple CArG boxes DNA sequence. Acts as a cofactor of serum response factor (SRF) with the potential to modulate SRF-target genes. Plays a crucial role in cardiogenesis and differentiation of the smooth muscle cell lineage (myogenesis). Isoform 1 mediates the cardiac transcription factor MEF2C-dependent transcription. Isoform 1 and isoform 3 are more active than isoform 2 and isoform 4 in stimulating cardiac muscle promoters. {ECO:0000269PubMed:11439182, ECO:0000269PubMed:12640126, ECO:0000269PubMed:12663482, ECO:0000269PubMed:16818234, ECO:0000269PubMed:20385216}.
Subcellular Localization Nucleus speckle {ECO:0000269PubMed:11439182, ECO:0000269PubMed:15601857}. Note=Nuclear, with a punctate intranuclear pattern with exclusion from nuclei.
Disease Associations
Tissue Specificity Expressed in heart, aorta, and in smooth muscle cell-containing tissues: stomach, bladder and uterus. Isoform 1 and isoform 3 are predominantly expressed in cardiac muscle whereas isoform 4 and isoform 5 are predominantly expressed in SMC-rich tissues. Isoform 3 is the most abundant isoform in the heart from embryo to adult. {ECO:0000269PubMed:11439182, ECO:0000269PubMed:12640126, ECO:0000269PubMed:12663482, ECO:0000269PubMed:14645532, ECO:0000269PubMed:20385216}.
