SOX12 (SoxC group) contains a C-terminal 33-residue transactivation domain (TAD) that is required for transcriptional activation; SOX12 is a weaker transactivator than SOX11 due to a less stable alpha-helical structure in its TAD. Acidic domains and the TAD interfere with DNA binding, and the three SoxC proteins can compete with one another in reporter gene transactivation. |

Sox12-deficient mice develop normally and are fertile, demonstrating that Sox4 and Sox11 functionally compensate for Sox12 loss during mouse development due to overlapping expression and higher transactivation rates, but compensation is not reciprocal (Sox12 cannot replace Sox4/Sox11). |

Sox12 directly binds to the Foxp3 promoter and drives its transcription in CD4+ T cells, promoting the differentiation of peripherally induced regulatory T (pTreg) cells during colitis. This induction of Sox12 expression occurs downstream of TCR-NFAT signaling. Sox12 is not required for thymus-derived Treg development. |
