Lysine-specific demethylase 4C is an enzyme that in humans is encoded by the KDM4Cgene.
Structure
This gene is a member of the Jumonji domain 2 (JMJD2) family and encodes a protein with one JmjC domain, one JmjN domain, two PHD-type zinc fingers, and two Tudor domains. This nuclear protein belongs to the alpha-ketoglutarate-dependent hydroxylase superfamily.
Function
It functions as a trimethylation-specific demethylase, converting specific trimethylated histone residues to the dimethylated form. Chromosomal aberrations and increased transcriptional expression of this gene are associated with esophageal squamous cell carcinoma. A expressional decrease of KDM4C was found during cardiac differentation of murine embryonic stem cells.
