Background

Function
MTA1 transcriptional coregulator which can act as both a transcriptional corepressor and coactivator. Acts as a component of the histone deacetylase NuRD complex which participates in the remodeling of chromatin. In the NuRD complex, regulates transcription of its targets by modifying the acetylation status of the target chromatin and cofactor accessibility to the target DNA. In conjunction with other components of NuRD, acts as a transcriptional corepressor of BRCA1, ESR1, TFF1 and CDKN1A. Acts as a transcriptional coactivator of BCAS3, and SUMO2, independent of the NuRD complex. Stimulates the expression of WNT1 by inhibiting the expression of its transcriptional corepressor SIX3. Regulates p53-dependent and -independent DNA repair processes following genotoxic stress. Regulates the stability and function of p53/TP53 by inhibiting its ubiquitination by COP1 and MDM2 thereby regulating the p53-dependent DNA repair. Plays a role in the regulation of the circadian clock and is essential for the generation and maintenance of circadian rhythms under constant light and for normal entrainment of behavior to light-dark (LD) cycles. Positively regulates the CLOCK-BMAL1 heterodimer mediated transcriptional activation of its own transcription and the transcription of CRY1. Regulates deacetylation of BMAL1 by regulating SIRT1 expression, resulting in derepressing CRY1-mediated transcription repression. With TFCP2L1, promotes establishment and maintenance of pluripotency in embryonic stem cells (ESCs) and inhibits endoderm differentiation; Binds to ESR1 and sequesters it in the cytoplasm and enhances its non-genomic responses[1][2][3][4][5][6][7][8].

Expression
Tissue_specificity:Widely expressed. High expression in brain, liver, kidney, and cardiac muscle, ovaries, adrenal glands and virgin mammary glands. Higher in tumors than in adjacent normal tissue from the same individual. Up-regulated in a wide variety of cancers including breast, liver, ovarian, and colorectal cancer and its expression levels are closely correlated with tumor aggressiveness and metastasis -
Isoforms & Post-Translational Modification
Q13330 has 3 isomers: Q13330-1: 80786 Da (predicted); Q13330-2: 49017 Da (predicted); Q13330-3: 79192 Da (predicted).
Phosphorylation by CSNK1G2/CK1 triggered by estrogen enhances corepression of estrogen receptor (ER);Acetylation is essential for its transcriptional coactivator activity;Sumoylation positively regulates its transcriptional corepressor activity but does not affect the protein stability. Sumoylated preferentially by SUMO2 or SUMO3 than SUMO1. Sumoylation is enhanced by PIAS1/3/4 and preferentially sumoylated by SUMO2 in the presence of PIAS1/3/4. Desumoylated by SENP1;Ubiquitinated by COP1, which leads to proteasomal degradation -
Subunit
Component of the nucleosome remodeling and deacetylase (NuRD) repressor complex, composed of core proteins MTA1, MTA2, MTA3, RBBP4, RBBP7, HDAC1, HDAC2, MBD2, MBD3, and peripherally associated proteins CDK2AP1, CDK2AP2, GATAD2A, GATAD2B, CHD3, CHD4 and CHD5 (PubMed:16428440, PubMed:28977666, PubMed:33283408, PubMed:9885572). The exact stoichiometry of the NuRD complex is unknown, and some subunits such as MBD2 and MBD3, GATAD2A and GATAD2B, and CHD3, CHD4 and CHD5 define mutually exclusive NuRD complexes (PubMed:16428440, PubMed:28977666, PubMed:33283408).
