PADI4: ELISA Kits

In vivo expression of PADI4 correlated with the appearance of citrulline in histones. We have shown that PADI4 converts arginines in the histone H3 tail to citrulline, that PADI4 blocks transcriptional activation and is recruited to the endogenous promotor. PADI4 represents a novel class of histone modifying enzymes probably linked to eostrogen regulated transcription.
