CC   -!- FUNCTION: Atypical Polycomb group protein, which may be involved in
CC       both Polycomb group (PcG) and trithorax group (trxG) complexes. Non-
CC       catalytic component of the PR-DUB complex, a complex that specifically
CC       mediates deubiquitination of histone H2A monoubiquitinated at 'Lys-118'
CC       (H2AK118ub1). Does not deubiquitinate monoubiquitinated histone H2B.
CC       Required to maintain the transcriptionally repressive state of homeotic
CC       genes throughout development. The PR-DUB complex has weak or no
CC       activity toward 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains. PcG
CC       and trxG proteins act by forming multiprotein complexes, which are
CC       respectively required to maintain the transcriptionally repressive and
CC       transcriptionally active state of homeotic genes throughout
CC       development. PcG and trxG protein complexes are not required to
CC       initiate repression and activation, but to maintain it during later
CC       stages of development. {ECO:0000269|PubMed:20436459,
CC       ECO:0000269|PubMed:9477319}.
CC   -!- SUBUNIT: Component of the PR-DUB complex, at least composed of calypso
CC       and Asx (PubMed:20436459). Interacts with tant (PubMed:11397012).
CC       Interacts with cyclin CycG (PubMed:25995770).
CC       {ECO:0000269|PubMed:11397012, ECO:0000269|PubMed:20436459,

CC       Q9V727; Q8T0D4: tant; NbExp=3; IntAct=EBI-103394, EBI-139891;
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:9477319}. Chromosome
CC       {ECO:0000269|PubMed:9477319}. Note=Associated with chromatin.
CC       Colocalizes with many PcG sites on polytene chromosomes. It also
CC       associates with many unique sites on polytene chromosomes.
CC   -!- TISSUE SPECIFICITY: Highly expressed in nurse cells and deposited in
CC       oocytes late in oogenesis. Ubiquitous in early embryos. Late embryos
CC       show higher levels in CNS and neurectoderm.
CC   -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. Early
CC       embryos have high levels of expression, this drops off and zygotic
CC       expression begins at 3-6 hours embryos. Expression levels are low in
CC       larvae and medium in pupae and adults. {ECO:0000269|PubMed:9477319}.
CC   -!- DOMAIN: Contains two Leu-Xaa-Xaa-Leu-Leu (LXXLL) motifs, which may be
CC       required for an association with nuclear receptors. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Asx family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAA04568.1; Type=Frameshift; Evidence={ECO:0000305};
