CC -!- FUNCTION: Smooth muscle cells (SM) and cardiac muscle cells-specific
CC transcriptional factor which uses the canonical single or multiple CArG
CC boxes DNA sequence. Acts as a cofactor of serum response factor (SRF)
CC with the potential to modulate SRF-target genes. Plays a crucial role
CC in cardiogenesis, urinary bladder development, and differentiation of
CC the smooth muscle cell lineage (myogenesis) (By similarity). Positively
CC regulates the transcription of genes involved in vascular smooth muscle
CC contraction (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:Q8R5I7}.
CC -!- SUBUNIT: Homodimer. Interacts with MLLT7/FOXO4. Interacts with SRF, its
CC association does not depend on specific DNA sequences for ternary
CC complex formation (By similarity). Interacts (via C-terminal) with
CC EP300 (via the CREB-binding domain) (By similarity). Interacts with
CC HDAC4 and HDAC5 (By similarity). Interacts with MEF2C (By similarity).
CC Interacts (via C-terminus) with STUB1/CHIP (By similarity). Interacts
CC with PURB (By similarity). {ECO:0000250|UniProtKB:Q8IZQ8,
CC ECO:0000250|UniProtKB:Q8R5I7, ECO:0000250|UniProtKB:Q8VIM5}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed in the heart and in smooth muscle cells-
CC containing tissues (aorta, pulmonary vein, lung), but is not detectable
CC in skeletal muscle, liver, kidney and spleen.
CC -!- DOMAIN: The C-terminal region contains a general transcription
CC activation domain. The N-terminal region, comprising a basic and a Gln-
CC rich domain, confers transcriptional potency and specificity by
CC mediating association with the MADS box of SRF. The basic domain may be
CC required for nuclear localization. The SAP domain is important for
CC transactivation and ternary complex formation (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Ubiquitinated; by STUB1/CHIP at the C-terminus, leading to its
CC degradation by the proteasome (By similarity). Phosphorylation by GSK3B
CC is required for STUB1/CHIP-mediated ubiquitination (By similarity).
CC {ECO:0000250|UniProtKB:Q8R5I7}.
CC -!- PTM: Phosphorylation negatively regulates the intrinsic myocardin
CC transcriptional activity (By similarity). Phosphorylated; by GSK3B (By
CC similarity). {ECO:0000250|UniProtKB:Q8R5I7,
CC ECO:0000250|UniProtKB:Q8VIM5}.
