    GlossaryPeptidylarginine Deiminase

    enzyme converting arginine in proteins to citrulline

    Peptidylarginine Deiminase (PAD) is an enzyme that converts arginine residues in proteins into citrulline through a process called deimination or citrullination. This modification can affect protein function and is involved in various physiological processes, including the regulation of gene expression and the formation of hair. Dysregulation of PAD activity has been linked to autoimmune diseases and conditions like alopecia.
