Biological Information
Background Information:
Eph (erythropoietin-producing hepatocellular) family tyrosine kinase receptors consist of two groups: EphA group members respond to ephrin-A, which is anchored to the cell membrane by glycosylphosphatidylinositol, whereas EphB group members respond to ephrin-B, containing a transmembrane domain. Among them, only EphA4 can cross-respond to both ephrin-A and -B. The expression of EphA8 receptor significantly promoted cell attachment to fibronectin without altering cellular integrin levels. Moreover, p110 phosphotidylinositol (PI) 3-kinase plays as a key bridging molecule between EphA8 and integrins. Inhibition. of EphA8 may disrupt establishment, maintenance, and remodeling of patterns of cellular organization and may also be used in the treatment of various cancers.

Testing Information
Procedure Summary:
EphA8 (h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 100 µM KTFCGTPEYLAPEVRREPRILSEEEQEMFRDFDYIADWC, 10 mM MgAcetate and [gamma-33P]-ATP (specific activity and concentration as required). The reaction is initiated by the addition of the Mg/ATP mix. After incubation for 40 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in methanol prior to drying and scintillation counting.
