Opis wartości docelowych

DNA-directed RNA polymerase II subunit RPB1 (UniProt: P24928; also known as EC:2.7.7.6; RNA polymerase II subunit B1, DNA-directed RNA polymerase II subunit A, DNA-directed RNA polymerase III largest subunit, RNA-directed RNA polymerase II subunit RPB1, POLR2A) is encoded by the POLR2A (also known as POLR2) gene (Gene ID: 5430) in human. DNA-directed RNA polymerase II subunit RPB1 is the catalytic component of RNA polymerase II that catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. It has multiple Zinc and magnesium ion binding sites. The binding of ribonucleoside triphosphate to the RNA polymerase II transcribing complex involves a two-step mechanism. The initial binding seems to occur at the entry (E) site and involves a magnesium ion temporarily coordinated by three conserved aspartate residues of the two largest RNA Pol II subunits. The ribonucleoside triphosphate is transferred by a rotation to the nucleotide addition (A) site for pairing with the template DNA. The catalytic A site involves three conserved aspartate residues of the RNA Pol II largest subunit which permanently coordinate a second magnesium ion. POLR2A is localized to cytoplasm in its hypo-phosphorylated form and the active hyper-phosphorylated form is located mainly in the nucleus. The tandem heptapeptide repeats (Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7) in its C-terminal domain (CTD) can be highly phosphorylated and regulates transcription coupled processes. Phosphorylation is shown to occur mainly at serine 2 and serine 5 residues of the heptapeptide repeat and is mediated by CDK7 and CDK9. Phosphorylation can also take place at serine 7 of the heptapeptide repeat, which is required for efficient transcription of snRNA genes and processing of the transcripts. Its C-terminal domain (aa 1593-1960) serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing. The K7-residues in non-consensus repeats of human RNAPII are modified by acetylation, or mono-, di-, and trimethylation. Acetylation of K7, and di- and tri-methylation of K7 are found exclusively associated with phosphorylated CTD peptides. Monomethylated K7 is found in non-phosphorylated CTD. Clone 3G21 targets both phosphorylated and non-phosphorylated YSPTSPS repeats in the C-terminal region. Q403K or L438H mutations in POLR2A are reported to hijack RNA polymerase II and drive neoplasia and POLR2A mutant tumors display dysregulation of key meningeal identity genes, including WNT6 and ZIC1/ZIC4. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
