    basic FUNCTION
  • having a potent histone demethylase activity but is expressed mainly in an inducible and cell-type restricted fashion (histone H3K27-specific demethylase)
  • expressed in macrophages in response to bacterial products and inflammatory cytokines
  • demethylating lys 27 on histone H3, leading to decreased levels of H3K27 and causing delocalization of polycomb proteins
  • may be involved in anterior-posterior development
  • histone demethylase controling differentiation in a self-renewing mammalian tissue
  • contributes to the control of gene expression in lipopolysaccharide-activated macrophages, and participates in the inflammatory transcriptional response induced by LPS stimulation in macrophages )
  • H3K27 demethylases, KDM6Band KDM6A, mediate a functional interaction between the lineage-defining T-box transcription factor family and a SMARCA4-containing SWI/SNF remodeling complex
  • has a required role in general chromatin remodeling that is independent from its H3K27 demethylase potential(
  • histone H3 Lys 27 (H3K27) demethylase KDM6B has been shown to play important roles in transcriptional regulation and cell differentiation
  • KDM4B and KDM6B promotes osteogenic differentiation of mesenchymal stem/stromal cells (MSCs)
  • H3K27 demethylation and specifically KDM6B and KDM6A catalytic activity are critical determinants of proinflammatory gene activation in human primary macrophages
  • histone demethylase promoting epithelial-mesenchymal transition
  • plays an important role in the transcriptional response to different signaling pathways
  • RNA polymerase II progression through H3K27me3-enriched gene bodies requires KDM6B histone demethylase
  • previously unrecognized role in cellular reprogramming and provide molecular insight into the mechanisms by which the KDM6B-PHF20 axis controls this process
  • is required for mesoderm differentiation and cardiovascular lineage commitment
  • JMJD3 controls the spermatogonial compartment through the regulation of fragmentation of spermatogonial cysts and this mechanism may be involved in maintenance of diverse stem cell niches
  • is a histone demethylase, which specifically catalyzes the removal of trimethylation of histone H3 at lysine 27 (H3K27me3)
  • novel function for KDM6B in activity-regulated neuronal survival, suggesting that activity- and KDM6B-dependent regulation of inflammatory gene pathways may serve as an adaptive pro-survival response to increased neuronal activity
  • regulates target gene expression in the embryonic stages of lung development
  • early embryonic H3K27me3 repression can be alleviated in the absence of active demethylation by KDM6A, KDM6B
  • is an epigenetic factor in T-cell differentiation via changes in histone methylation and target gene expression
  • H3K27me3 demethylase that counteracts polycomb-mediated transcription repression
  • is a key epigenetic regulator in the process of cartilage maturation during endochondral bone formation
  • KDM6B and KDM6A are required for T-cell development, and point to a requirement for their H3K27Me3 demethylase activity in cell differentiation

    small molecule metal binding,
  • binding Fe(II)
  • protein
  • binds Polycomb group target genes
  • interacting with HOXA11, which is a target in differentiating bone marrow cells (but in macrophages is an inactive gene with high and constant H3K27me3 levels during stimulation)
  • association with RBBP5-containing complexes
  • demethylation of H3K27me3 in the NFATC1 gene locus by KDM6B plays a critical role in TNFSF11-induced osteoclast differentiation
  • KDM6B and KDM7A play a role in localizing elongation factors SUPT6H and SUPT16H to the target genes
  • KDM6A and KDM6B contribute to the activation of WNT3 and DKK1 at different differentiation stages when WNT3 and DKK1 are required for mesendoderm and definitive endoderm differentiation, respectively
  • following commitment to megakaryocyte differentiation, the H3K27 demethylase KDM6B up-regulation influences both ITGA2B and MPL expression
  • regulates transcription of transforming growth factor beta (TGFbeta)-responsive genes by promoting RNA polymerase II (RNAPII) progression along the gene bodies
  • chromatin regulators EP300, KDM5A, KDM6A and KDM6B cooperate with KLF4 in promoting the transcription of POU5F1
  • KDM6B-targeting of PHF20 for ubiquitination and degradation via recruitment of an E3 ligase, TRIM26
  • plays important roles in osteoblast differentiation and regulates the expressions of IBSP and BGLAP via transcription factors RUNX2 and SP7
  • KDM6B associates with RUNX2 to promote proliferation and hypertrophy of chondrocytes
  • role of KDM6B as a novel inducer of senescence-associated heterochromatin foci (SAHF), formation through demethylating RB1
