Protocol

Specificity / Sensitivity

IWS1 Antibody detects endogenous levels of total IWS1 protein.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human IWS1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Various steps in gene expression, such as mRNA processing, surveillance, export, and synthesis are coupled to transcription elongation (1,2). The C-terminal domain (CTD) of the large subunit of RNA polymerase II plays an important role in the integration of these different steps (1,2). IWS1 interacts with Spt6, a CTD-binding transcription elongation factor and H3 chaperone (1,2). IWS1 also recruits another CTD-binding protein, HYPB/Setd2 histone methyltransferase, to the RNA polymerase II complex for elongation-coupled H3K36 trimethylation (2). Thus, IWS1 links Spt6 and HYPB/Setd2 in a large complex and regulates mRNA synthesis and histone methylation at the co-transcriptional level (2).
