General description

RPB3 is one of 12 subunits that make up the complete RNA polymerase, Pol II, the primary RNA polymerase in cellular metabolism. RPB3 is part of the core element of Pol II complex. RPB3 has a central large cleft and the clamp element that moves to open and close the cleft during RNA synthesis. RPB3 naturally localizes to the nucleus and expressed in all cell types and tissues. RPB3 also plays critical roles in RNA splicing and capping, key items of RNA function.

Immunogen

KLH-conjugated linear peptide corresponding to human RPB3 near the Near C-terminus.

Application

Anti-RPB3 Antibody is an antibody against RPB3 for use in Western Blotting.

Quality

Evaluated by Western Blotting in HUVEC cell lysate.

Western Blotting Analysis: A 1:500 dilution of this antibody detected RPB3 in 10 µg of HUVEC cell lysate.

Target description

~35 kDa observed

Control of RNA Polymerase II (pol II) elongation is a critical component of gene expression in mammalian cells. The PNUTS-PP1 complex controls elongation rates, slowing pol II after polyadenylation sites to promote termination. The Kaposi's sarcoma-associated herpesvirus (KSHV) co-opts pol

In response to stress, human cells coordinately downregulate transcription and translation of housekeeping genes. To downregulate transcription, the negative elongation factor (NELF) is recruited to gene promoters impairing RNA polymerase II elongation. Here we report that NELF rapidly forms nuclear

Precise control of the RNA polymerase II (RNA Pol II) cycle, including pausing and pause release, maintains transcriptional homeostasis and organismal functions. Despite previous work to understand individual transcription steps, we reveal a mechanism that integrates RNA Pol II cycle
