Although ABL1 is reported to phosphorylate Y130 of p85-bound RhoGDI2 upon PSGL-1 ligation (16), we haven’t found any scholarly report that ABL1 phosphorylation in Y24 and Y130 of RhoGDI2 is involved in the migration of T-ALL cells toward CXCL12, suggesting the involvement of ABL1 in T-ALL. This evidence concerns the gene SELPLG and acute lymphoblastic leukemia.
