Though we could not find any published data which show overexpression of BLES03 in basophilic leukemia, it was interesting to note that in RBL-2H3.2 cell line (low releasing variant of Rat Basophilic Leukemia) Thr phosphorylation by Protein Kinase C δ (PKCδ) on γ chain of FcεR1 is delayed and the same variant has defect in PKC activity (Bingham et al. 1994). This evidence concerns the gene C11orf68 and acute basophilic leukemia.
