Summaries for PURB Gene

Entrez Gene Summary for PURB Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for PURB Gene

PURB (Purine Rich Element Binding Protein B) is a Protein Coding gene. Diseases associated with PURB include Myelodysplastic Syndrome. GO annotations related to this gene include poly(A) RNA binding and RNA binding. An important paralog of this gene is PURA.

UniProtKB/Swiss-Prot for PURB Gene

  • 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 (By similarity).

    Miscellaneous:
    • Defects in PURB may be a cause of progression of myelodysplastic syndrome (MDS) towards acute myelogenous leukemia (AML). MDS refers to a heterogeneous group of closely related hematopoietic disorders. All are characterized by a cellular marrow with impaired morphology and maturation (dysmyelopoiesis) and peripheral blood cytopenias, resulting from ineffective blood cell production. Some patients with MDS develop acute myelogenous leukemia (AML), a malignant disease in which hematopoietic precursors are arrested in an early stage of development.
