Phosphatidylserine Receptor (PSR)

Bifunctional arginine demethylase and lysyl-hydroxylase JMJD6 is 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 suggested that the protein may cross-react with a monoclonal antibody that recognizes the phosphatidylserine receptor and does not directly function in the clearance of apoptotic cells. Multiple transcript variants encoding different isoforms have been found for this gene.
