Product Overview

Tag	N/A
Host Species	Human
Synonym	Transcriptional activator protein Pur-beta, Purine-rich element-binding protein B, PURB, PURBETA.
Background	Purine-Rich Element Binding Protein B (PURB) is a single-stranded DNA-binding protein which takes part in the dendritic transport of a subset of mRNAs. PURB operates as repressor in myoblasts and fibroblasts in the control of vascular smooth muscle alpha-actin gene transcription. PURB binds preferentially to the single strand of the purine-rich element termed PUR, which is present at origins of replication and in gene flanking regions in various eukaryotes from yeasts through humans.
Description	PURB Human Recombinant expressed in E.coli is a single, non-glycosylated polypeptide chain containing 335a.a. (1-312) and having a molecular weight of 35.6 kDa.PURB is fused to a 23a.a. His-Tag at N-terminus and purified by unique purification methods.
Source	E.coli
