Recombinant Human Transcriptional activator protein Pur-beta (PURB)

Uniprot Id

Q96QR8

Target Species

Human

Target Name

PURB

Target Full Name

Transcriptional regulator protein Pur-beta

Target Function

Has capacity to bind repeated elements in single-stranded DNA such as the purine-rich single strand of the PUR element located upstream of the MYC gene. Plays a role in the control of vascular smooth muscle (VSM) alpha-actin gene transcription as repressor in myoblasts and fibroblasts. Participates in transcriptional and translational regulation of alpha-MHC expression in cardiac myocytes by binding to the purine-rich negative regulatory (PNR) element. Modulates constitutive liver galectin-3 gene transcription by binding to its promoter. May play a role in the dendritic transport of a subset of mRNAs

Target Subcellular Location

Nucleus.

Target Protein Families

PUR DNA-binding protein family

Target Tissue Specificity

Expressed in myocardium of heart failure patients.

Target Synonyms

Pur beta; purB; PURB_HUMAN; PURBETA; Purine rich element binding protein B; Purine-rich element-binding protein B; transcriptional activator protein Pur beta; Transcriptional activator protein Pur-beta

Target Background

This gene product is a sequence-specific, single-stranded DNA-binding protein. It 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 a variety of eukaryotes from yeasts through humans. Thus, it is implicated in the control of both DNA replication and transcription. Deletion of this gene has been associated with myelodysplastic syndrome and acute myelogenous leukemia.
