1 Reconstitution of the complete tetrameric Fc epsilon RI receptor, lyn and syk in a non-hematopoietic "null" cell line is sufficient to reconstruct clustering-controlled receptor tyrosine phosphorylation and activation of syk, without apparent requirement for hematopoietic specific phosphatases. Tyrosine Fc epsilon receptor Ia Homo sapiens
2 Lyn also participates in the tyrosine phosphorylation and activation of syk in a manner which is dependent on phosphorylated Fc epsilon RI. Tyrosine Fc epsilon receptor Ia Homo sapiens
3 Based on these results, we propose that receptor clustering controls lyn-mediated Fc epsilon RI tyrosine phosphorylation by shifting a balance between phosphorylation and dephosphorylation towards accumulation of tyrosine phosphorylated Fc epsilon RI. Tyrosine Fc epsilon receptor Ia Homo sapiens
4 Based on these results, we propose that receptor clustering controls lyn-mediated Fc epsilon RI tyrosine phosphorylation by shifting a balance between phosphorylation and dephosphorylation towards accumulation of tyrosine phosphorylated Fc epsilon RI. Tyrosine Fc epsilon receptor Ia Homo sapiens
5 Based on these results, we propose that receptor clustering controls lyn-mediated Fc epsilon RI tyrosine phosphorylation by shifting a balance between phosphorylation and dephosphorylation towards accumulation of tyrosine phosphorylated Fc epsilon RI. Tyrosine Fc epsilon receptor Ia Homo sapiens
6 Based on these results, we propose that receptor clustering controls lyn-mediated Fc epsilon RI tyrosine phosphorylation by shifting a balance between phosphorylation and dephosphorylation towards accumulation of tyrosine phosphorylated Fc epsilon RI. Tyrosine Fc epsilon receptor Ia Homo sapiens
7 Fc epsilon RI tyrosine phosphorylation functions to bring syk into a microenvironment where it becomes tyrosine phosphorylated and activated, thereby allowing clustering to indirectly control syk activity. Tyrosine Fc epsilon receptor Ia Homo sapiens
8 Fc epsilon RI tyrosine phosphorylation functions to bring syk into a microenvironment where it becomes tyrosine phosphorylated and activated, thereby allowing clustering to indirectly control syk activity. Tyrosine Fc epsilon receptor Ia Homo sapiens
