Gene Information

human ... RIPK1(8737)

General description

RIPK1 (receptor -interacting serine-threonine kinase 1) is a necroptosis regulatory protein. It is a serine-threonine kinase containing a death domain. It contains a kinase domain in its N-terminal, RIP homotypic interaction motif, and its C-terminal contains the death domain.
RIPK1 gene is located at 6p25.2 on the human chromosome.


Receptor-interacting serine/threonine-protein kinase 1 recombinant protein epitope signature tag (PrEST)


Anti-RIPK1 antibody produced in rabbit has been used in immunoblotting and immunohistochemistry.
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Biochem/physiol Actions

RIPK1 (receptor -interacting serine-threonine kinase 1) acts as a signaling molecule in tumor necrosis factor α (TNFα)-induced necroptosis. Necrostatins interact with this protein, to inhibit necroptosis. When induced by TNFα, it forms a component of the prosurvival complex I, which also includes TRADD (TNFR1-associated DD-protein), TRAF2 (TNF receptor-associated factor 2), cIAP1 (cellular inhibitor of apoptosis protein-1), and cIAP2. It is overexpressed in human melanoma, and acts as an oncogene for the same. This up-regulation is achieved due to NF-κB and TNFα, and results in tumor growth and proliferation. It is also up-regulated in gallbladder cancer, and its suppression results in reduced tumor growth and proliferation. It is also up-regulated in glioblastomas, and this is related to malignancy, as well as poor prognosis in glioblastoma patients. In primary and metastatic osteosarcoma, an anti-tumor agent shikonin is capable of inducing cell death by activating RIPK1.

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.
