Actin dynamics controlled by IqgC, a RasGAP at the crossroads between the IQGAP and fungal GAP1 families.
Review in FEBS open bio, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In addition to transmitting receptor-mediated signals to adjust the gene expression profile of the cell, small GTPases of the Ras family also control the remodelling of the actin cytoskeleton. The conversion of Ras GTPases from their active to their inactive form is controlled by Ras GTPase-activating proteins (RasGAPs). IqgC, a RasGAP from Dictyostelium discoideum, was originally assigned to the IQGAP family, but its sequence and recent functional analyses show that IqgC is more closely related to RasGAPs from the GAP1 family of fungi. IqgC has two prominent domains, a RasGAP domain and a C-terminal RGCt domain, and interacts with Ras, Rab and Rap GTPases, but shows GTPase-promoting activity only towards Ras. IqgC suppresses macroendocytosis but supports cell-substratum adhesion and directed cell migration. Its localisation to macroendocytic cups is mediated by the RasGAP domain, whereas its localisation in ventral focal adhesions is mediated by the RGCt domain. We hypothesise that IqgC plays an important role in the balance between the competing feeding and migratory behaviour of amoeboid D. discoideum cells.
