Gene Snapshot
Ataxin 7 (Atxn7) encodes a component of the SAGA chromatin modifying complex, which is responsible for acetylation of histones and deubiquitination of the product of His2B at active promoters. The product of Atxn7 anchors the non-stop containing deubiquitinase module to the remainder of SAGA. Atxn7 is an essential gene for larval survival, neural development, and maintenance of neural tissues. [Date last reviewed: 2019-03-07]

    SAGA COMPLEX -
    The Spt-Ada-Gcn5 Acetyltransferase (SAGA) complex is a chromatin modifying complex. SAGA can acetylate and deubiquitinate histone residues. Also SAGA has been shown to regulate the transcriptional activation of a subset of genes. (Adapted from FBrf0228923, FBrf0219841 and FBrf0233349).
