HIPK2 (homeodomain interacting protein kinase 2) gene encodes a serine/threonine kinase belonging to the homeodomain-interacting protein kinase family and the sub family of dual-specificity Yak1-related kinase proteins. It functions as a co-repressor for homeodomain transcription factors. It contains an interaction domain for homeoproteins, a corepressor domain (CRD), PEST sequence, and a protein kinase domain along with a YH domain in the C terminus. It is localized to nuclear speckles by means of a speckle-retention signal and is covalently modified by the ubiquitin-like protein SUMO-1.
Synonyms: Anti-Homeodomain-interacting protein kinase 2; Anti-hHIPk2
Storage: -20C
Application: 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: HIPK2 (homeodomain interacting protein kinase 2) functions as a co-repressor for homeodomain transcription factors. It plays a vital role in the transcriptionaal regulation and apoptosis. During apoptosis induction, it phosphorylates the p53 protein at Ser 46 to facilitate p53-dependent gene expression and subsequent apoptosis. It also controls the activation of c-Jun NH2-terminal kinase (JNK) via TGF-ß signaling pathway.
