HGK assay

Hepatocyte progenitor kinase-like/germinal center kinase-like kinase

Synonyms: MAP4K4, FLH21957, “HPK/GCK-like kinase”, NIK

Family: STE

HGK is a member of the human STE20/mitogen-activated protein kinase kinase kinase kinase family of serine/threonine kinases1. HGK is expressed in all tissue types, but appears to express at relatively higher levels in the brain and testis. HGK plays essential role in embryonic development, and has also been implicated in focal adhesion dynamics regulation, systemic inflammation, lung inflammation, type 2 diabetes, atherosclerosis, and insulin sensitivity2.

HGK kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
