The Abpromise guarantee
Our Abpromise guarantee covers the use of ab76933 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application | Abreviews | Notes |
---|---|---|
WB |
1/2000 - 1/10000. Predicted molecular weight: 55 kDa.
|
|
IP |
Use at 2-5 µg/mg of lysate.
|
|
ICC |
1/50 - 1/2000.
Formaldehyde fixation is recommended. Permeabilization with Triton-X 100 is recommended for formaldehyde-fixed cells |

Target

Function
DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I which synthesizes ribosomal RNA precursors. Isoform 1 is involved in UBTF-activated transcription, presumably at a step following PIC formation.
Isoform 2 has been described as a component of preformed T-cell receptor (TCR) complex. -
Sequence similarities
Belongs to the eukaryotic RPA34 RNA polymerase subunit family. -
Post-translational
modificationsIsoform 2 undergoes tyrosine phosphorylation upon T-cell receptor (TCR) stimulation. This phosphorylation has not been confirmed by other group.
Isoform 1 is phosphorylated on tyrosine residues in initiation-competent Pol I-beta complexes but not in Pol I-alpha complexes.
Phosphorylated upon DNA damage, probably by ATM or ATR. -
Cellular localization
Nucleus > nucleolus. Chromosome. Found at the fibrillar centers of the nucleolus in interphase and during cell division it is localized to the nucleolus organizer regions of the chromosomes. - Information by UniProt

Predicted band size: 55 kDa
Observed band size: 75 kDa why is the actual band size different from the predicted?
Additional bands at: 130 kDa. We are unsure as to the identity of these extra bands. -
