SGF73/YGL066W Summary Help

Standard Name SGF73 1
Systematic Name YGL066W
Alias SCA7 2
Feature Type ORF, Verified
Description SAGA complex subunit; has a role in anchoring the deubiquitination module into SAGA and SLIK complexes; involved in preinitiation complex assembly at promoters; relocalizes to the cytosol in response to hypoxia; human ortholog ataxin-7 is associated with spinocerebellar ataxia diseases; mutant displays reduced transcription elongation in the G-less-based run-on (GLRO) assay (1, 2, 3, 4, 5, 6, 7, 8)
