In these studies , AlFx and Na3VO4 stimulated rapid tyrosine phosphorylation of Ig alpha , Ig beta , and additional cellular proteins , including the protein tyrosine kinase ( PTK ) Lyn . ^^^ Interestingly , the extent and kinetics of the mIg associated Lyn and Ig alpha / Ig beta phosphorylation was correlated , suggesting that Lyn may mediate receptor phosphorylation . ^^^ Alternatively , Lyn , may be a downstream effector of phosphorylated Ig alpha and Ig beta as suggested by the reported ability of biphosphorylated Ig alpha to activate Fyn PTK in vitro . ^^^ The data are consistent with modulation of phosphorylation of Ig alpha and Ig beta through both PTP inhibition and AlFx treatment , and a common intermediary in or effector of these phosphorylation pathways appears to be the Lyn kinase . . ^^^ |

Cross linking of the IgM receptor induces rapid translocation of IgM associated Ig alpha , Lyn , and Syk tyrosine kinases to the membrane skeleton . ^^^ Furthermore , two BCR associated kinases that are known to play critical roles in anti IgM induced B cell signaling , the src family kinase Lyn and the non src family kinase Syk , accumulate in the membrane skeleton shortly after BCR cross linking , when most of IgM and Ig alpha accumulate in this fraction . ^^^ The kinetics of recruitment of the bulk of Ig alpha , Lyn , and Syk into the membrane skeleton appeared to precede the accumulation of their hypertyrosine phosphorylated forms , suggesting that activation of the BCR associated signaling molecules occurs in this fraction . ^^^ |

The cross linking of the B cell Ag receptor ( BCR ) leads to the initiation of a signal transduction cascade in which the earliest events involve the phosphorylation of the immunoreceptor tyrosine based activation motifs of Ig alpha and Ig beta by the Src family kinase Lyn and association of the BCR with the actin cytoskeleton . ^^^ |

Flow cytometry , combined Western blot immunoprecipitation kinase assays , and confocal microscopy revealed that both the nonpairing and pairing mu HC assembled with the Ig alpha beta dimer ; however , in contrast to a pairing mu HC , the nonpairing mu HC was retained in the ER cis Golgi compartment , and neither colocalized with the src kinase lyn nor induced tyrosine phosphorylation of Ig alpha after pervanadate treatment of cells . ^^^ |
