Metastasis-associated protein MTA1 (MTA1)

Transcriptional coregulator which can act as both a transcriptional corepressor and coactivator. As a component of the histone-deacetylase multiprotein complex (NuRD), regulates transcription of its targets by changing the acetylation status of the target chromatin and cofactor accessibility to the target DNA.

Along with other elements of NuRD, acts as a transcriptional corepressor of BRCA1, ESR1, TFF1 and CDKN1A. Stimulates the expression of WNT1 by inhibiting the expression of its transcriptional corepressor SIX3.
