Overview

Product name	POLR2B Rabbit pAb
Catalog No.	A5928
Host species	Rabbit
Purification method	Affinity purification
Isotype	IgG

Background

This gene encodes the second largest subunit of RNA polymerase II (Pol II), a DNA-dependent RNA polymerase that catalyzes the transcription of DNA into precursors of mRNA, snRNA and microRNA. This subunit and the largest subunit form opposite sides of the center cleft of Pol II. Deletion of the flap loop region of this subunit results in a decrease in the rate of transcriptional elongation. Alternative splicing results in multiple transcript variants.
