Title	Analysis of the TCR signalosome in primary T cells
Description	T-cell receptor (TCR) signaling is essential for the function of T cells. Here we combine mouse genetics and affinity purification coupled to quantitative mass spectrometry to monitor the composition and dynamics of the signaling complexes that assemble around 15 nodes of the TCR signaling cascade of primary CD4+ T cells. This dataset contains the experiments performed with 14 different bait proteins • Cbl • Cblb • Fyb • Inpp5d • Itk • Lck • Lcp2 • Nck1 • Nfatc2 • Plcg1 • Ptpn22 • Ptpn6 • Themis • Vav1 Each of them contains mass spectrometry results from the analysis of AP-MS experiments, based on the endogenous expression of One-Strep-tagged (OST) bait proteins in engineered mice models, and affinity purification of these proteins from primary CD4+ T cells, using Streptactin beads. Purification of OST proteins was performed at 5 different time points of stimulation of CD4+ T cells with anti-CD3 and anti-CD4 antibodies (0s; 30s; 120s; 300s; 600s). Each AP-MS purification of an OST- protein is associated with a corresponding control (purification from WT CD4+ T cells) at the same time point of stimulation. Several biological replicate experiments (time course OST series + associated WT controls) were performed for each bait. Several MS replicates were acquired for each sample. In addition, we analyzed the total proteome of CD4+ T cells isolated from each engineered mice model (14 different mice expressing an OST bait) and from WT mice, in order to calculate copy numbers of the baits and their associated proteins.
