and CD3 chains) and membrane-associated proteins provides docking
sites for SH2 domains of adaptor proteins and signaling enzymes,
resulting in their recruitment in the vicinity of activated receptors.
pp36/38 is a prominent substrate of early tyrosine phosphorylation upon
stimulation through the T cell receptor. The tyrosine-phosphorylated
form of pp36/38 is membrane-associated and directly interacts with
phospholipase C-
1 and Grb2, providing one mechanism to recruit
downstream effectors to the cell membrane. Here, we demonstrate that in
Jurkat T cells, pp36/38 associates with the p85 subunit of
phosphatidylinositol 3-kinase (PI-3-K p85) in an activation-dependent
manner. Association of pp36/38 with PI-3-K p85 was confirmed by
transfection of a hemagglutinin-tagged p85
cDNA into Jurkat cells
followed by anti-hemagglutinin immunoprecipitation. In vitro binding experiments with glutathione S-transferase fusion
proteins of PI-3-K p85 demonstrated that the SH2 domains, but not the
SH3 domain, mediated binding to pp36/38. This binding was selectively
abrogated by phosphopeptides that bind to p85 SH2 domains with high
affinity. Filter binding assays demonstrated that association between
pp36/38 and PI-3-K p85 SH2 domains was due to direct binding. These
results strongly suggest the role of pp36/38 in recruiting PI-3-K to
the cell membrane and further support the idea that pp36/38 is a
multifunctional docking protein for SH2 domain-containing signaling
proteins in T cells.
