Description: Transcriptional corepressor which facilitates transcriptional repression via its association with DNA-binding transcription factors and recruitment of other corepressors and histone-modifying enzymes (PubMed:12559562, PubMed:15203199). Can repress the expression of MMP7 in a ZBTB33-dependent manner (PubMed:23251453). Reduces the protein levels and stability of the transcriptinal regulator HIF1A; interacts with EGLN1 and promotes the HIF1A prolyl hydroxylation-dependent ubiquitination and proteasomal degradation pathway (PubMed:25974097). Contributes to inhibition of glycolysis and stimulation of mitochondrial respiration by down-regulating the expression of glycolytic genes including PFKFB3, PFKFB4, PDK1, PFKP, LDHA and HK1 which are direct targets of HIF1A (PubMed:23840896, PubMed:25974097). Regulates the proliferation and the differentiation of erythroid progenitors by repressing the expression of TAL1 target genes (By similarity). Plays a role in granulocyte differentiation (PubMed:15231665).

Subunit Structure: Homooligomer. Homotetramerization is mediated by nervy homology region 2 (NRH2) (By similarity). Can interact with RUNX1T1 and CBFA2T2; heterotetramerization between members of the CBFA2T family is proposed (PubMed:12242670). Component of a TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3 (By similarity). Interacts with ERBB4, HDAC1, HDAC2, HDAC3, HDAC6, HDAC8, NCOR1, NCOR2, and ZNF652. According to PubMed:12242670, may not interact with HDAC6. Interacts with PLXNA1, PLXNA3 and PRKAR1A. Isoform 2 interacts with PRKAR2A, PDE7A and probably PDE4A. Interacts with ZBTB4, ZBTB38 and ZBTB33. Interacts with HIF1A and EGLN1. Interacts with the AML1-MTG8/ETO fusion protein.

Similarity: Nervy homology region 2 (NHR2) mediates homo- and possibly heterotypic oligomerization by forming a four-helix bundle tetrameric structure. Belongs to the CBFA2T family
