Msl2 | E3 ubiquitin-protein ligase MSL2; Component of histone acetyltransferase complex responsible for the majority of histone H4 acetylation at lysine 16 which is implicated in the formation of higher-order chromatin structure (By similarity). Acts as an E3 ubiquitin ligase that promotes monoubiquitination of histone H2B at 'Lys-35' (H2BK34Ub), but not that of H2A. This activity is greatly enhanced by heterodimerization with MSL1. H2B ubiquitination in turn stimulates histone H3 methylation at 'Lys-5' (H3K4me) and 'Lys-80' (H3K79me) and leads to gene activation, including that of HOXA9 and [...] (577 aa) | ||||
Tmprss11d | Transmembrane protease serine 11D non-catalytic chain; May play some biological role in the host defense system on the mucous membrane independently of or in cooperation with other substances in airway mucous or bronchial secretions. Preferentially cleaves the C-terminal side of arginine residues at the P1 position of certain peptides (By similarity). Plays a role in the proteolytic processing of ACE2. Isoform 2 may play a key role in regulating adrenal proliferation by specifically cleaving N-POMC; Belongs to the peptidase S1 family. (417 aa) |
