General description

RNA polymerase II (RNAPII or Pol II) is a multi-subunit enzyme responsible for the transcription of transcription of DNA into RNA from protein-coding genes. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. RNAPII can coordinate 10 to 14 subunits. This complex interacts with the promoter regions of genes and a variety of elements and transcription factors. The DNA binding domain of the polymerase is a groove where TFIIB orients the DNA for unwinding and transcription.
~220 kDa observed

Immunogen

Ovalbumin-conjugated linear peptide corresponding to human RNAPII phosphorylated at Tyr1.

Application

Detect the phospho-RNAPII (Tyr1) protein using this Anti-phospho-RNAPII (Tyr1), clone 3D12 validated for use in WB, IP & ChIP.
Immunoprecipitation Analysis: A representative lot from an independent laboratory detected phospho-RNAPII (Tyr1) in proliferating yeast whole cell extract (Mayer, A., et al. (2012). Science. 336(6089):1723-1725.).

Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot from an independent laboratory immunoprecipitated phospho-RNAPII (Tyr1) in proliferating yeast whole cell extract (Mayer, A., et al. (2012). Science. 336(6089):1723-1725.).
