| Taken together , our results showed that , in M 07e cells , Lyn protein tyrosine kinase ( p53 / p56lyn ) is stably associated with a constitutively phosphorylated beta subunit of the GM CSFR in a manner that seems to be independent of lyn kinase activity . . 0.77036766^^^ Finally , the interaction of Lyn kinase with the GM CSFR complexes was further corroborated using anti GM CSF ( G 133 ) mAb , which coimmunoprecipitated both the p 120 beta subunit and lyn product in the lysates of M 07e cells that had been bound with rhGM CSF before cell lysis . 0.50625345^^^ |
