Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant human PADI4 protein. Background Peptidyl arginine deiminase (PAD) proteins are a family of Ca -dependent enzymes that catalyze the post-translational conversion of arginine to citrulline. There are currently five known PAD isozymes in humans, referred to as PADI1-4 and PADI6 (1). PADI4 is a nuclear member of the PAD family and is responsible for deiminating R2, R8, R17, and R26 on the histone H3 (2-4). Deimination of histone residues prevents CARM1-mediated arginine methylation and results in transcriptional repression (2,3). Expression of PADI4 is increased during myeloid differentiation and various polymorphisms have been implicated in rheumatoid arthritis (5-8). PADI4 can play a role in apoptosis and cell cycle arrest upon DNA damage, as it is recruited to the p21 promoter by p53 and also regulates a subset of p53 target genes (9,10). Hypercitrullination of histones by PADI4 contributes to chromatin decondensation and the formation of neutrophil extracellular traps (NETs) to combat bacterial infection in a process called NETosis (11,12). Inhibition of PADI4 reduces NET formation, making it a potential therapeutic target (13).
