Conjugate | Avi-tag Biotinylated E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag. |

This POLR2A protein is a semi-custom product. There are 5 expression system options: Yeast, E. coli, In Vivo Biotinylation in E. coli, Baculovirus, and Mammalian cell. Your requirements will be given top priority in determining the protein tags. For proteins within 800 aa, risk-free custom service is guaranteed. It means you will not be charged if the protein cannot be delivered.
POLR2A encodes the largest subunit of RNA polymerase II that transcribes DNA into RNA. POLR2A regulates various biological processes, including transcription, cell cycle progression, and chromatin remodeling [1] [2] [3]. Mutations in POLR2A have been linked to specific types of tumors. Recurrent somatic POLR2A mutations have been identified in meningiomas [4]. POLR2A also promotes the proliferation of cancer cells such as in gastric cancer, by advancing cell cycle progression [5].
Furthermore, POLR2A has been found to interact with other proteins such as CREB1, to regulate transcription and cellular processes like osteoclastic bone resorption [6]. Studies have also shown that POLR2A positively regulates histone modifications such as H3K4me3, suggesting its role in establishing chromatin conformation and gene expression patterns [2]. Moreover, variations in the length of certain genetic markers, like the poly-T variant in SCAF4, can influence the binding of POLR2A and impact the transcription of nearby genes, potentially contributing to disease processes like amyotrophic lateral sclerosis [7].
