Research Abstract |
Peptidylarginine deiminase (PADI) 4 deiminates preferentially core histones in HL-60 granulocytes and bloodstream granulocytes stimulated with calcium ionophore. In this study we determined the deimination sites of histones. Deiminated histone H4 and H2A were isolated and digested with proteases. Their degests were separated by RP-HPLC. Deiminated peptides were identified by mass spectrometry. The deimination occurred at R3 of the N-terminal sequence Ac-SGRGK common to H2A and H4. This indicates that the target site in vivo for PADI4 is very restricted. As for a role of PADI4, we found that PADI4 can act as a repressor for transcriptional activation of pS2 promoter by estrogen. PADI4 antagonizes dimethylation of histone H3 R17 which is required for transcription of the promoter by deiminating monomethyl arginine and arginine into citrulline. Crystal structures of Ca^<2+> free PADI4 and Ca^<2+> bound PADI4 mutants with and without substrate revealed that Ca^<2+> binding induces conformational changes that generates the active site cleft.
