Protein-arginine deiminase type-2 is an enzyme that in humans is encoded by the PADI2 gene.This gene encodes a member of the peptidyl arginine deiminase family of enzymes which catalyze the post-translational deimination of proteins by converting arginine residues into citrullines in the presence of calcium ions. The family members have distinct substrate specificities and tissue-specific expression patterns. The type II enzyme is the most widely expressed family member.
