UniProtKB - Q9V727 (ASX_DROME)
Protein
Polycomb protein Asx
Gene
Asx
Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
Atypical Polycomb group protein, which may be involved in both Polycomb group (PcG) and trithorax group (trxG) complexes. Non-catalytic component of the PR-DUB complex, a complex that specifically mediates deubiquitination of histone H2A monoubiquitinated at 'Lys-118' (H2AK118ub1). Does not deubiquitinate monoubiquitinated histone H2B. Required to maintain the transcriptionally repressive state of homeotic genes throughout development. The PR-DUB complex has weak or no activity toward 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains. PcG and trxG proteins act by forming multiprotein complexes, which are respectively required to maintain the transcriptionally repressive and transcriptionally active state of homeotic genes throughout development. PcG and trxG protein complexes are not required to initiate repression and activation, but to maintain it during later stages of development.2 Publications

Expressioni
Tissue specificityi
Highly expressed in nurse cells and deposited in oocytes late in oogenesis. Ubiquitous in early embryos. Late embryos show higher levels in CNS and neurectoderm.
Developmental stagei
Expressed both maternally and zygotically. Early embryos have high levels of expression, this drops off and zygotic expression begins at 3-6 hours embryos. Expression levels are low in larvae and medium in pupae and adults.1 Publication
