Immunoprecipitation - Anti-RNA polymerase beta antibody [EPR18704] (AB191598)

RNA polymerase beta was immunoprecipitated from 1mg of E.coli whole cell lysates with ab191598 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab191598 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500.

Supplementary information

RNA polymerase beta also known as RpoB or DNA-directed RNA polymerase subunit beta is a critical enzyme in the transcription process. This protein has a molecular mass of approximately 150 kDa. RpoB plays a role by catalyzing the synthesis of RNA from a DNA template an essential step in gene expression. It is widely expressed in bacteria mitochondria chloroplasts and also in the nuclei of eukaryotic cells. RpoB functions as a fundamental part of the core RNA polymerase complex which also includes other subunits such as alpha beta' and omega.
Biological function summary

RpoB interacts with multiple subunits to form the RNA polymerase holoenzyme integrating into cellular machinery to initiate transcription. This enzyme participates in synthesizing mRNA rRNA and tRNA all of which are important for protein synthesis. The holoenzyme formation aligns with promoter regions on DNA enabling precise transcription initiation. Without the proper function of RpoB and its associated subunits transcription efficiency and fidelity could be compromised impacting cell viability.

Pathways

RNA polymerase beta is integral to transcriptional regulation pathways and genetic response mechanisms within the cell. It plays a role in the bacterial transcription pathway directly interacting with sigma factors and other transcription regulators to manage gene expression in response to environmental changes. Furthermore RpoB operates in conjunction with other proteins like sigma factors which allow the enzyme to recognize specific promoter sequences ensuring the transcription of appropriate genes.

The improper function of RNA polymerase beta has correlations with bacterial resistance to antibiotics notably rifampicin. Mutations in the rpoB gene can lead to resistance complicating treatment strategies for conditions like tuberculosis. This enzyme's relationship with sigma factors also presents a route through which these mutations affect transcription fidelity leading to resistant bacterial strains. Understanding these connections helps to develop therapies targeting the bacterial transcription machinery effectively.

Target data

DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.. Resistance to the antibiotics salinamide A, salinamide B, rifampicin, streptolydigin, CBR703, myxopyronin, and lipiarmycin can result from mutations in this protein.. Part of the processive rRNA transcription and antitermination complex (rrnTAC). The complex forms an RNA-chaperone ring around the RNA exit tunnel of RNAP. It supports rapid transcription and antitermination of rRNA operons, cotranscriptional rRNA folding, and annealing of distal rRNA regions to allow correct ribosome biogenesis.
