Lysine-specific demethylase 4A is an enzyme that in humans is encoded by the KDM4Agene.[1][2][3]
Function
This gene is a member of the Jumonji domain 2 (JMJD2) family and encodes a protein with a JmjN domain, a JmjC domain, a JD2H domain, two TUDOR domains, and two PHD-type zinc fingers. This nuclear protein belongs to the 2-oxoglutarate (2OG)-dependent dioxygenase superfamily. It functions as a trimethylation-specific demethylase, converting specific trimethylated histone on histone H3 lysine 9 and 36 residues to the dimethylated form and lysine 9 dimethylated residues to monomethyl, and as a transcriptional repressor.[3]
Alterations in this gene have been found associated with chromosomal instability that leads to cancer.(PMID23871696)
