GO:0007012actin cytoskeleton reorganizationPMID:30845261ECO:0005598 IMP: Inferred from Mutant PhenotypeBiological Process
The CNF1 protein in E.coli induces changes in the organization of the actin cytoskeleton, which prevents cytoadherence and induces the detachment of pRBCs from endothelial mono-layers. This may be used in preventing malaria parasite cytoadherence.

GO:2000251 positive regulation of actin cytoskeleton reorganization PMID:30845261 ECO:0006062 IGI: Inferred from Genetic Interaction P In Figure 4 they use florescence microscopy to confirm the CNF1 protein in E.coli induces changes in the organization of the actin cytoskeleton in stress fibers and membrane protrusions, which prevents cytoadherence. This is shown through the addition of CNF1 protein and other inhibitors. With the addition of CNF1 compared to the control you can see the rearrangement of the cytoskeleton but, in the presence of inhibitors along with CNF1 the modifications of rearrangement are decreased. complete

Nice blurb, but does not say anything about the experimental setup/rationale in the paper that allows the authors to draw such conclusion. This should be a description of the experimental process supporting the annotation, not of the paper. One presumes you are talking about figure 4, where a mutant toxin is shown to have effects on endothelial cell actin cytoskeleton. If so, something more specific than mutant phenotype could be used. The GO is wrong too, since CNF1 "induces" changes in the cytoskeleton and, as a bacterial protein, it may be hard to argue that it is "involved" in the reorganization, which is a BP of the endothelial cell.

Please use the cross-linked evidence terms from ECO (i.e. those that end in "used in manual assertion" or "used in automatic assertion") Most instances of evidence you will come across will be of type "used in manual assertion". Terms with "used in automatic assertion" imply that the authors did not make a conscious effort to analyze the results of an experiment, letting an algorithm make the call. For instance, if somebody were to use BLAST to determine that a bunch of proteins are homologous (and hence have the same function as the query) and they do not assess the BLAST results in any way (just accept whatever BLAST returns as significant given a preestablished threshold) that could be thought of as an "automatic assertion".
