General description
RPB1 (RNA polymerase II subunit B1) is the catalytic component of RNA polymerase II which synthesizes mRNA and non-coding RNAs. During transcription, elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of RPB1, which acts as an assembly platform for factors regulating transcription initiation, elongation, termination and mRNA processing. Phosphorylation occurs mainly at residues ′Ser-2′ and ′Ser-5′ of the tandem 7 residue repeats in the C-terminal domain (CTD), which activates Pol II. This phosphorylation also can occur at ′Ser-7′ of the heptapepdtide repeat. This antibody recognizes the ′Ser-5′ CTD residue of RPB1.
Specificity
This antibody recognizes RNA Polymerase II subunit B1 phosphorylated at Ser5 of the C-terminus domain (CTD).
Immunogen
Epitope: Phosphorylated Ser5 at the C-terminus domain (CTD).

The general transcription factor P-TEFb, a master regulator of RNA polymerase (Pol) II elongation, phosphorylates the C-terminal domain (CTD) of Pol II and negative elongation factors to release Pol II from promoter-proximal pausing. We show here that P-TEFb surprisingly inhibits

Ibrutinib, a bruton's tyrosine kinase (BTK) inhibitor, provokes robust clinical responses in aggressive mantle cell lymphoma (MCL), yet many patients relapse with lethal Ibrutinib-resistant (IR) disease.

RNA polymerase II (RNAPII) transcription initiates bidirectionally at many human protein-coding genes. Sense transcription usually dominates and leads to messenger RNA production, whereas antisense transcription rapidly terminates. The basis for this directionality is not fully understood. Here, we show that
