Gene Snapshot
INO80 complex subunit (Ino80) encodes a component of the INO80 chromatin remodelling complex that interacts with Polycomb and Trithorax group proteins. It is involved in the regulation of homeotic gene expression and regression of ecdysone dependent transcription. [Date last reviewed: 2019-02-28]
Gene Group (FlyBase)
INO80 COMPLEX -
The INO80 complex is an ATP-dependent chromatin remodeller that can mobilize nucleosomes. (Adapted from PMID:17316710).
SNF2-LIKE CHROMATIN REMODELERS -
Snf2-like chromatin remodelers are a family of helicase-like proteins that direct energy derived from ATP hydrolysis into the mechanical remodelling of chromatin structure. They are so-called due to the presence of a domain homologous to the helicase-like ATPase domain of the S. cerevisiae Snf2 protein. This domain, the Snf2 domain, consists of two tandem RecA-like folds and contains seven conserved helicase-related sequence motifs that classify it as part of the helicase superfamily 2 (SF2). However, Snf2 proteins are not bona fide helicases, lacking the ability to separate nucleic acid strands. Instead, Snf2 proteins are DNA translocases that apply an ATP-dependent torsional strain to DNA, which provides the necessary force to remodel nucleosomes or in some cases other DNA-protein complexes. (Adapted from PMID:21862382.)
Protein Function (UniProtKB)
ATPase component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and DNA repair. Binds DNA. As part of the INO80 complex, remodels chromatin by shifting nucleosomes.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        • New stable cell line derived from S2-Invitrogen : Stable S2 cell lines were created to study chromatin remodeling. The base S2[OsTir1] was created and selected core proteins from the four main sub-families of ATP-dependent chromatin remodelers (Snr1, Iswi, Ino80, and Chd1) as well as SWI/SNF component Brd7-9 were inserted to create S2OsTir1-Snr1-AID, S2OsTir1-Iswi-AID, S2OsTir1-Ino80-AID, S2OsTir1-Chd1-AID, and S2OsTir1-Brd7-AID for component depletion studies.
