Gene Information

human ... HNRNPK(3190)

General description

HNRNPK (heterogeneous nuclear ribonucleoprotein K) gene encodes a member of the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins that are associated with pre-mRNAs and mediate mRNA processing, metabolism and transport. The encoded protein has three repeats of KH domains that bind to RNA. It tenaciously binds to poly(C).

Immunogen

Heterogeneous nuclear ribonucleoprotein K recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

HNRNPK (heterogeneous nuclear ribonucleoprotein K) protein is a nucleocytoplasmic shuttling protein that functions as a cofactor for p53 in mediating transcriptional induction of factors that regulate DNA repair, cell-cycle progression, or cell survival in response to DNA damage. Upon DNA damage, hnRNP K undergoes sumoylation through Pc2 E3 (E3 ligase) activity and activates p53 transcription. Deletion of this gene fails to induce transcription of p53 target genes and causes defects in DNA-damage-induced cell-cycle-checkpoint arrests.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

In response to DNA damage, mammalian cells trigger the p53-dependent transcriptional induction of factors that regulate DNA repair, cell-cycle progression, or cell survival. Through differential proteomics, we identify heterogeneous nuclear ribonucleoprotein K (hnRNP K) as being rapidly induced by DNA
