“Analysis of specific gp140trk immunoprecipitates indicated that addition of NGF to B cells induced a rapid increase in the tyrosine phosphorylation of gp140trk and inhibition of this phosphorylation prevented the tyrosine phosphorylation of other proteins.”
“ NGF caused both concentration‐ and time‐dependent increases in tyrosine phosphorylation of five proteins of 140, 110, 85, 60 and 42 kDa, which were identified as phospholipase C‐γ1, phosphatidylinositol‐3 kinase and mitogen‐activated protein kinase.”
