rnk Antibody (464B) is an IgG1 mouse monoclonal rnk antibody (also designated rnk antibody) suitable for the detection of the rnk protein of E. coli origin by WB and ELISA. rnk Antibody (464B) is available as the non-conjugated anti-rnk antibody. RNA polymerase transcribes DNA to synthesize RNA using the four ribonucleoside triphosphates as substrates. In prokaryotes, a catalytic core known as RNAP is formed from α, β and σ RNA pol subunits that, once complexed, can initiate transcription. The RNAP-interacting protein, rnk (regulator of nucleoside kinase) is a 136 amino acid protein that is structurally similar to the secondary channel effectors known as Gre factors. E. coli Gre factors and DksA are competitively inhibited by rnk in vitro. Cellular concentrations of rnk are similar to GreB, indicating a role as regulator of secondary channel effectors. In vitro studies indicate that rnk neither directly inhibits RNAP promoter interaction nor initiates transcript cleavage.
