RT   "Cytoplasmic ATXN7L3B interferes with nuclear functions of the SAGA
RT   deubiquitinase module.";
RL   Mol. Cell. Biol. 36:2855-2866(2016).
CC   -!- FUNCTION: By binding to ENY2, interferes with the nuclear functions of
CC       the deubiquitinase (DUB) module of the SAGA complex which consists of
CC       ENY2, ATXN7, ATXN7L3 and the histone deubiquitinating component USP22.
CC       Affects USP22 DUB activity toward histones indirectly by changing the
CC       subcellular distribution of ENY2 and altering ENY2 availability for
CC       ATXN7L3 interaction. Regulates H2B monoubiquitination (H2Bub1) levels
CC       through cytoplasmic sequestration of ENY2 resulting in loss of nuclear
CC       ENY2-ATXN7L3 association which destabilizes ATXN7L3. Affects protein
CC       expression levels of ENY2 and ATXN7L3. {ECO:0000269|PubMed:27601583}.
CC   -!- SUBUNIT: Interacts strongly with ENY2. Interacts weakly with USP22.
CC       {ECO:0000269|PubMed:27601583}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:27601583}.
CC   -!- DISEASE: Note=A chromosomal aberration involving ATXN7L3B has been
CC       found in a mother and her two children with varying degrees of
CC       neurodevelopmental delay and cerebellar ataxia. One child also exhibits
CC       episodes of unresponsiveness suggestive of absence seizures and facial
CC       dysmorphism. Deletion at 12q21.1 deletes the entire single exon of
CC       ATXN7L3B. {ECO:0000269|PubMed:23475819}.
CC   -!- MISCELLANEOUS: Encoded by an expressed retrotransposed copy of the
CC       ATXN7L3 locus that emerged prior to the speciation event separating
CC       primates and rodents.
CC   -!- SIMILARITY: Belongs to the SGF11 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAH09111.1; Type=Erroneous translation; Note=Wrong choice of CDS.; Evidence={ECO:0000305};
