EphB6 is a member of the receptor tyrosine kinase family expressed primarily in thymic cells and T cell subpopulations. EphB6, when stimulated by ephrin-B2, inhibited JNK activation, and decreased T-cell receptor-induced IL-2 secretion and CD25 expression. EphB6 promotes colorectal epithelial cell transformation and may serve as a novel biomarker and therapeutic target for colorectal cancer. EphB6 Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived EphB6 protein, expressed by HEK293 , with C-hFc labeled tag.
