Autocitrullination of human peptidyl arginine deiminase type 4 regulates protein citrullination during cell activation
3 Mar 2010
Abstract excerpt
OBJECTIVE: To address mechanisms that control the activity of human peptidyl arginine deiminase type 4 (PAD-4). METHODS: PAD-4 autocitrullination was determined by anti-modified citrulline immunoblotting, using purified recombinant and endogenous PAD-4 from activated human primary neutrophils and cell lines expressing PAD-4. The citrullination sites in PAD-4 were determined by mass spectrometry. Mechanisms of...
