Graphs show average fold-change in protein levels (top) and significant fold-change in phosphorylation levels at indicated sites with indicated multiplicity, upon synchronous optogenetic induction of cell-cell fusion by light. The median time for fusion in 20 min.

Each graph shows individual biological replicates and average trace (bold). For each graph, the p-value indicates the probability that the trace is at constant value. The covariation probes whether the slope of the phosphorylation change is identical to that of the global protein levels. #N/A indicates the test was not done.
