In addition to this work, Araujo-Abad et al. (2023; 2024) predicted the citrullinating enzyme PADI4 (PROTEIN-ARGININE DEIMINASE 4)-epigenetic factor RYBP (RING1 AND YY1 BINDING PROTEIN) complex and PADI4 with the two fragments of the transcriptional repressor C-RING1B and N-RING1B complex in human cancer cells by using the protein-protein docking algorithm ClusPro. Here, RYBP is linked to cancer.
