Kat8 | Histone acetyltransferase KAT8; Histone acetyltransferase which may be involved in transcriptional activation. May influence the function of ATM. As part of the MSL complex it is involved in acetylation of nucleosomal histone H4 producing specifically H4K16ac. As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. That activity is less specific than the one of the MSL complex. Can also acetylate TP53/p53 at 'Lys-120'. Belongs to the MYST (SAS/MOZ) family. (458 aa) | ||||
Rchy1 | RING finger and CHY zinc finger domain-containing protein 1; Mediates E3-dependent ubiquitination and proteasomal degradation of target proteins, including p53/TP53, P73, HDAC1 and CDKN1B. Preferentially acts on tetrameric p53/TP53. Increases AR transcription factor activity. Monoubiquitinates the translesion DNA polymerase POLH (By similarity). Contributes to the regulation of the cell cycle progression. (261 aa) |
