产品说明

一般描述

RNA polymerase II subunit B1 (RPB1) is the largest subunit of the RNA polymerase II complex. As a holoenzyme RNA polymerase II catalyzes transcription of eukaryotic DNA into RNA using the four ribonucleoside triphosphates as substrates. The RPB1 subunit, in combination with other polymerase subunits, forms a large central cleft that maintains contact between the active site of the enzyme, the DNA template, and the nascent RNA transcript. This subunit also contains a carboxy terminal domain (CTD) consisting of tandem heptapeptide repeats. In actively transcribing RNA polymerase ‘Ser-2’ and ‘Ser-5’ of the heptapeptide repeat are phosphorylated. Phosphorylation activates the RNA polymerase II beta subunit, allowing it to serve as an assembly platform for additional subunits that modulate initiation, elongation, termination and mRNA processing.

免疫原

KLH-conjugated linear peptide corresponding to human RNA polymerase II subunit B1.

应用

Use Anti-RNA polymerase II subunit B1 Antibody, clone 4F8 (rabbit polyclonal antibody) validated in WB, ICC to detect RNA polymerase II subunit B1 also known as DNA-directed RNA polymerase II subunit RPB1.
