| Post Translational Modifications | Ubiquitinated.by STUB1/CHIP at the C-terminus, leading to its degradation by the proteasome. Phosphorylation by GSK3B is required for STUB1/CHIP-mediated ubiquitination. Phosphorylation negatively regulates the intrinsic myocardin transcriptional activity. Phosphorylated.by GSK3B. |
| 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, urinary bladder development, and differentiation of the smooth muscle cell lineage (myogenesis). Positively regulates the transcription of genes involved in vascular smooth muscle contraction. |
