Essential for citrullinated protein research

Anti PAD2(Peptidylarginine Deiminase 2) polyclonal antibody



Peptidylarginine deiminases (PADs) are a group of post-translational modification enzymes that citrullinate (deiminate) protein arginine residues in a calcium ion-dependent manner, yielding citrulline residues. In mammalian tissues, PADs are found as five different isoforms (PAD1, PAD2, PAD3, PAD4/5 and PAD6). Among them, only PAD2 (76-kDa protein) is a proven occupant of the central nervous system. Immunocytochemical studies have localized PAD2 in glial cells, especially astrocytes, microglial cells and oligodendrocytes. Also PAD2 expressed in multiple tissues including the epidermis, skeletal muscle, kidney, lung, spleen, pancreas, stomach, intestine, ovary, uterus, testis and leukocyte. Citrullinated proteins are known to be involved in the onset of various diseases such as articular rheumatism, Alzheimer's disease, multiple sclerosis and psoriasis.
