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. The presence of anti-citrullinated protein antibody is a standard test for … See more Citrullinated peptides and proteins can be detected using antibodies targeting the citrullinated residues, or detected using mass spectrometry-based proteomics technologies. Citrullination of arginine results in a monoisotopic mass increase of +0.984016 Da, … See more WebNov 6, 2024 · Autoantibodies to citrullinated proteins (ACPAs) are present in two-thirds of patients with rheumatoid arthritis (RA). ACPAs are produced in the absence of identified T cell responses for each citrullinated protein. Peptidyl arginine deiminase 4 (PAD4), which binds proteins and citrullinates them, is the target of autoantibodies in early RA. reach penalties
