Biochem/physiol Actions

KDM6B (lysine demethylase 6B) is responsible for the demethylation of histone H3K27. At promoters it demethylates the repressive H3K27me3 and therefore, promotes gene expression. In human and mouse fibroblasts, it demethyates the H3K27me3 at INK4a/ARF (alternate reading frame) locus, thus, promoting the expression of p16 protein, and therefore, acts as a tumor suppressor. It is also involved in inflammatory pathways in macrophages and embryonic stem cell differentiation. The expression of KDM6B is elevated in clear cell renal cell carcinoma (ccRCC) where it promotes EMT (epithelial to mesenchymal transition). Increased expression is also linked positively with lymph node metastasis, tumor size, cancer stage and poor prognosis.

General description

KDM6B (lysine demethylase 6B)/ JMJD3 (jumonji domain-containing 3) is a major histone demethylase protein. This protein contains a JmjC domain in its C-terminal.

Modulators and Proteins for Methylation

DNA methyltransferases are a family of enzymes that catalyze the transfer of a methyl group to DNA. There are five related DNA cytosine-5-methyltransferases (DNMTs) that transfer a methyl group from ...
