Related Product Information for HGK active protein
HGK is the mitogen-activated protein kinase kinase kinase kinase 4(MAP4K4) and a member of the serine/threonine protein kinase family. HGK has been shown to specifically activate MAPK8/JNK. The activation of MAPK8 by HGK can be inhibited by dominant-negative mutants of MAP3K7/TAK1, MAP2K4/MKK4, and MAP2K7/MKK7, which suggest that this kinase functions through the MAP3K7-MAP2K4-MAP2K7 kinase cascade and mediates TNF-a signaling. HGK-dependent signaling inhibits PPAR?-responsive gene expression, adipogenesis, and insulin-stimulated glucose transport.

NCBI Description

The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase has been shown to specifically activate MAPK8/JNK. The activation of MAPK8 by this kinase is found to be inhibited by the dominant-negative mutants of MAP3K7/TAK1, MAP2K4/MKK4, and MAP2K7/MKK7, which suggests that this kinase may function through the MAP3K7-MAP2K4-MAP2K7 kinase cascade, and mediate the TNF-alpha signaling pathway. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Uniprot Description

HGK: a Ser/Thr kinase of the STE20 subfamily. May play a role in the response to environmental stress and cytokines such as TNF-alpha. May interact with the SH3 domain of the adapter proteins Nck. Binds, via its CNH regulatory domain, to the N- terminal region of SPG3A. Upregulated in primary tumors and tumor cell lines. Required for anchorage-independent growth and ras-dependent focus formation in multiple cell lines. 5 isoforms of the human protein are produced by alternative splicing.

Protein type: Kinase, protein; EC 2.7.11.1; Protein kinase, STE; Protein kinase, Ser/Thr (non-receptor); STE group; STE20 family; MSN subfamily

Chromosomal Location of Human Ortholog: 2q11.2-q12

Cellular Component: cytoplasm

Molecular Function: protein serine/threonine kinase activity; protein binding; ATP binding; receptor signaling protein serine/threonine kinase activity

Biological Process: microvillus biogenesis; regulation of catalytic activity; regulation of JNK cascade; protein amino acid phosphorylation

Product Notes

The HGK map4k4 (Catalog #AAA4160166) is an Active Protein produced from Insect Cells and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "HGK, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
