Background
This gene encodes a nuclear protein with a JmjC domain. JmjC domain-containing proteins are predicted to function as protein hydroxylases or histone demethylases. This protein was first identified as a putative phosphatidylserine receptor involved in phagocytosis of apoptotic cells; however, subsequent studies have indicated that it does not directly function in the clearance of apoptotic cells, and questioned whether it is a true phosphatidylserine receptor. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008],
Function
caution:Was initially thought to constitute the phosphatidylserine receptor, a receptor that mediates recognition of phosphatidylserine, a specific marker only present at the surface of apoptotic cells. Phosphatidylserine receptor probably participates in apoptotic cell phagocytosis. This protein was identified using phage display expressing mAb 217, an antibody that specifically recognizes phosphatidylserine receptor. However, its nuclear localization and the fact that mAb 217 antibody still recognizes the phosphatidylserine receptor in mice lacking JMJD6, strongly suggest that it does not constitute the receptor for phosphatidylserine and is not involved in apoptotic cell removal.,domain:The nuclear localization signal motifs are necessary and sufficient to target it into the nucleus.,function:Arginine demethylase which demethylates histone H3 at 'Arg-2' (H3R2me) and histone H4 at 'Arg

Cellular localization
Nucleus, nucleoplasm . Nucleus, nucleolus . Cytoplasm . Mainly found throughout the nucleoplasm outside of regions containing heterochromatic DNA, with some localization in nucleolus. During mitosis, excluded from the nucleus and reappears in the telophase of the cell cycle. .
Tissue expression
Highly expressed in the heart, skeletal muscle and kidney. Expressed at moderate or low level in brain, placenta, lung, liver, pancreas, spleen, thymus, prostate, testis and ovary. Up-regulated in many patients with chronic pancreatitis. Expressed in nursing thymic epithelial cells.
