Lat, an adapter protein essential for t-cell signaling, is phosphorylated at its thr 155 by erk in response to t-cell receptor stimulation. Thr 155 phosphorylation reduces the ability of lat to recruit plcgamma1 and slp76, leading to attenuation of subsequent downstream events such as [ca2+]i mobilization and activation of the erk pathway. |

Thr 155 phosphorylation reduces the ability of lat to recruit plcgamma1 and slp76, leading to attenuation of subsequent downstream events such as [ca2+]i mobilization and activation of the erk pathway.Mutational analysis revealed that t155 but not t94 or t140 is the site of jnk-mediated phosphorylation (figure 2b). Erk also phosphorylated lat at t155 (figure 2c), whereas p38, which was able to phosphorylate atf2, failed to induce threonine phosphorylation of lat (figure 2d). These results indicate that lat is directly phosphorylated by erk and jnk at the same site, t155. |

By substituting these tyrosine residues in LAT with phenylalanine and by utilizing phosphorylated peptides derived from these sites, we mapped the tyrosine residues in LAT required for the direct interaction and activation of Vav, p85/p110alpha and phospholipase Cgamma1 (PLCgamma1). Our results indicate that Tyr(226) and Tyr(191) are required for Vav binding, whereas Tyr(171) and Tyr(132) are necessary for association and activation of phosphoinositide 3-kinase activity and PLCgamma1 respectively. |

Interestingly, this study has demonstrated that the membrane-proximal region of linker for activation of T cells preceding tyrosine-132 mediates its association with TRAF6, which promotes the ubiquitination of linker for activation of T cells and, in turn, the phosphorylation of tyrosine residues on linker for activation of T cells.|Moreover, LAT was ubiquitinated at Lysine 88 by TRAF6 via K63 linked chain. |
