Protein complex found in Drosophila consisting of the gene products of cuff, del and rhi. It regulates the licensing of transcription of dual-strand PIWI interacting RNA (piRNA) source loci by binding to dual-strand-cluster chromatin, probably via the H3K9me3-binding activity of Rhi. Rhi binding brings the putative termination cofactor Cuff in close proximity to the nascent piRNA precursor transcript which it appears to protect from degradation.

A general transcription initiation factor activity that contributes to transcription start site selection and transcription initiation of genes transcribed by RNA polymerase III. Factors required for RNA polymerase III transcription initiation include TFIIIA, TFIIIB and TFIIIC. RNA polymerase III transcribes genes encoding short RNAs, including tRNAs, 5S rRNA, U6 snRNA, the short ncRNA component of RNases P, the mitochondrial RNA processing (MRP) RNA, the signal recognition particle SRP RNA, and in higher eukaryotes a number of micro and other small RNAs, though there is some variability across species as to whether a given small noncoding RNA is transcribed by RNA polymerase II or RNA polymerase III.

A molecular function required for core promoter activity that mediates the assembly of the RNA polymerase holoenzyme at promoter DNA to form the pre-initiation complex (PIC). General transcription factors (GTFs) bind to and open promoter DNA, initiate RNA synthesis and stimulate the escape of the polymerase from the promoter. Not all subunits of the general transcription factor are necessarily present at all promoters to initiate transcription. GTFs act at each promoter, although the exact subunit composition at individual promoters may vary.

The sumoylation by a protein of one or more of its own amino acid residues, or residues on an identical protein.

The process in which a SUMO protein (small ubiquitin-related modifier) is conjugated to a target protein via an isopeptide bond between the carboxy-terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein.

A NuA3 complex that catalyzes the acetylation of Histone H3. In S. cerevisiae, this complex consists of Eaf6p, Nto1p, Sas3p, Taf14p, Yng1p and associates with H3K4me3 using Yng1p.

Binding to an RNA polymerase II core enzyme, a multisubunit eukaryotic nuclear RNA polymerase typically composed of twelve subunits.

Binding to a component of the basal transcription machinery for RNA polymerase II which is composed of the RNA polymerase II core enzyme, a multisubunit eukaryotic nuclear RNA polymerase typically composed of twelve subunits, and the basal RNA polymerase II transcription factors, the minimal set of factors required for formation of the preinitiation complex (PIC) by the RNA polymerase.

Binding to an RNA polymerase core enzyme, containing a specific subunit composition defined as the core enzyme.

Any process that modulates the frequency, rate or extent of xyloglucan metabolic process.

Catalysis of the reaction: (R)-2-hydroxyacid + a quinone = 2-oxoacid + a quinol.

Binding to an RNA polymerase III core enzyme, a multisubunit eukaryotic nuclear RNA polymerase typically composed of seventeen subunits.

Any process that stops, prevents or reduces the frequency, rate or extent of xyloglucan metabolic process.

Catalysis of the reaction a long-chain aldehyde + O(2) + 2 NADPH = an alkane + formate + H(2)O + 2 NADP(+).

OBSOLETE. Binding to an RNA polymerase II (Pol II) complex, typically composed of twelve subunits, in order to modulate transcription. A protein binding transcription factor may or may not also interact with the template nucleic acid (either DNA or RNA) as well.

Omega-shaped (as in the Greek capital letter) intracellular membrane-bounded organelle enriched in phosphatidylinositol 3-phosphate and dynamically connected to the endoplasmic reticulum. Omegasomes are the first step of the formation of autophagosomes via the phagophore assembly sites.

Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by RNA polymerase III. The transcribed region might be contain a single gene or a cistron containing multiple genes.

Binding to a DNA region that controls the transcription of a gene by RNA polymerase III. Binding may occur as a sequence specific interaction or as an interaction observed only once a factor has been recruited to the DNA by other factors.

Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by some RNA polymerase. The proximal promoter is in cis with and relatively close to the core promoter.
