| Rbbp5 | Retinoblastoma-binding protein 5 homolog; Component of the SET1 complex that specifically di- and trimethylates 'Lys-4' of histone H3 and of the MLL3/4 complex which also methylates histone H3 'Lys-4'. (489 aa) | ||||
| Ptip | PAX transcription activation domain interacting protein (Ptip) encodes a component of a Histone H3K4 methyltransferase complex that contributes to Trithorax-mediated epigenetic imprinting during development. (2294 aa) | ||||
| Set1 | Histone-lysine N-methyltransferase SETD1; Catalytic component of the SET1 complex that specifically di- and trimethylates 'Lys-4' of histone H3 and is the main di- and trimethyltransferase throughout development. Set1-dependent trimethylation regulates chromatin changes at active promoters that ensure optimal RNA polymerase II release into productive elongation, thereby contributing to optimal transcription. (1641 aa) | ||||
| Utx | Utx histone demethylase (Utx) encodes a Jumonji C containing protein that catalyzes the removal of methyl groups from Histone H3 lysine 27. Together with the products of trr and Lpt, it is thought to regulate chromatin structure at transcriptional enhancers. (1136 aa) | ||||
