WebWhat is Anti-CCP? Anti-CCP antibodies are directed against citrullinated proteins. Citrullination results from the post-translational modification (ie. not encoded in the original protein) of the amino acid arginine to citrulline by the enzyme peptidyl arginine deiminase. Anti-CCP assays recognize a number of citrullinated proteins. WebSep 1, 2024 · Anti-citrullinated protein antibodies (ACPAs) are well-established biomarkers for rheumatoid arthritis (RA), which are believed to arise in the context of aberrant peptidyl arginine deiminase (PAD) citrullination. Of the five human isoforms, PAD2 and PAD4 are considered most likely to be involved in disease pathogenesis.
Webcitrullinated protein antibodies (ACPAs) can be detected in those with RA. These ACPAs bind specific proteins that have undergone a citrullination process that makes them immunogenic. Citrulline is a derivative of the amino acid arginine, so any protein containing arginine is capable, in theory, of becoming citrullinated, which is irreversible.
