EPH-A3 assay

EPH receptor A3

Synonyms: HEK, HEK4, ETK, ETK1, TYRO4

Family: TK

EPHA3 is a receptor tyrosine kinase that is involved in cell viability, cell movement and cell-cell interactions1. Binding and activation of Eph-receptor family members requires cell-cell interactions2. High levels of EphA3 protein expression have been reported in colorectal, prostate, and gastric cancers, whereas loss of protein expression has been reported in lung and hematopoietic cancers3.

EPHA3 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.
