We confirmed these data on the human orthologues thr336 and thr363. Moreover, the enhanced stoichiometry of lkb1 autophosphorylation by strad enabled us to identify two novel sites: thr185 and thr402. We sh... | SIGNOR-101844 |
P43405 | P31995 | 1 | phosphorylation | up-regulates activity | 0.2 | Fyn and Blk definitely phosphorylate Y-282 in the ITAM of FcgRIIa/c, whereas the non-ITAM tyrosine residue (Y-275) becomes phosphorylated by Syk, as the phosphorylation of double point mutants shows.
