ATG proteins recruit the centrosome-associated protein PCM1, after BCR engagement. ATG16L1 was immunoprecipitated by a label-free method. Partners have been identified by spectrum number counting. The table shows the number of identified spectra for the indicated proteins on the left, in the following conditions: control (CTRL) immunoprecipitation with beads only (IP), IP-ATG16L1, for 3 independent biological and experimental replicates. In each case, non-stimulated (NS) or BCR-stimulated (S) conditions were evaluated. For each experiment, the ratio of spectra numbers between stimulated and non-stimulated conditions is indicated.
