Citrullinated arginine
Did you know?
Citrullination or deimination is the conversion of the amino acid arginine in a protein into the amino acid citrulline. Citrulline is not one of the 20 standard amino acids encoded by DNA in the genetic code. Instead, it is the result of a post-translational modification. Citrullination is distinct from the … See more PADs are found in chordates but not in lower animals. In mammals five PAD isotypes – PAD1, PAD2, PAD3, PAD4 and PAD6 – have been found. PAD5 was thought to be a unique isotype in humans, however it was … See more In rheumatoid arthritis and other autoimmune diseases, such as psoriatic arthritis, systemic lupus erythematosus and Sjögren's syndrome, autoantibodies often attack citrullinated proteins.
