The function of Ensembl gene identifier ENSG00000057935 (MTA3, metastasis associated 1 family member 3) is as follows. Acts as a component of the histone deacetylase NuRD complex which participates in the remodeling of chromatin (PubMed:12705869, PubMed:16428440, PubMed:28977666). Plays a role in maintenance of the normal epithelial architecture through the repression of SNAI1 transcription in a histone deacetylase-dependent manner, and thus the regulation of E-cadherin levels (PubMed:12705869). Contributes to transcriptional repression by BCL6 (PubMed:15454082). {ECO:0000269|PubMed:12705869, ECO:0000269|PubMed:15454082, ECO:0000269|PubMed:16428440, ECO:0000269|PubMed:28977666}.
