MTA3 is a cell-type-specific subunit of the Mi-2/NuRD corepressor complex that physically interacts with the transcription factor BCL-6 to mediate BCL-6-dependent repression of plasma cell differentiation genes in germinal center B cells; this interaction is sensitive to BCL-6 acetylation status, and MTA3 depletion by RNAi impairs BCL-6-dependent repression. |

Mouse Mta3 (60 kDa) localizes to both nucleus and cytoplasm when GFP-tagged and expressed in keratinocytes, in contrast to Mta1 which is exclusively nuclear; Mta1 nuclear localization requires at least one NLS and one SH3 binding site, and Mta1 SH3 ligands interact with Grb2 and Fyn. |

MTA3 interacts with NuRD proteins CHD4 and HDAC1 and the cohesin subunit RAD21 in mouse ovarian granulosa cells; MTA3 depletion slows granulosa cell proliferation (rescued by re-expression of exogenous MTA3), reduces cyclin B1 and B2 expression, and causes accumulation of cells in G2/M phase with reduced histone H3-Ser10 phosphorylation, indicating a role in G2/M progression. |

In trophoblast cells, MTA3 directly occupies the proximal promoter regions of CGB5 (hCG β-subunit) and Snail as shown by ChIP; siRNA-mediated knockdown of MTA3 increases CGB5 and Snail promoter activity and their mRNA levels, establishing MTA3 as a direct transcriptional repressor of both genes. |

BCL-6 middle domain (RDII) recruits MTA3 to repress Prdm1 (Blimp1) and other target genes in T follicular helper (Tfh) cells; mimicked acetylation of BCL-6 K379Q prevents MTA3 recruitment and derepresses Prdm1, reducing Tfh differentiation in vivo; loss of BCL-6/MTA3 function could be partially rescued by abrogating Prdm1 expression. |
