Non-SUMOylatable septin variants form aberrant bundles. (a) Fluorescent light microscopy images of HeLa cells transfected with HA-tagged WT or non-SUMOylatable SEPT7 and SEPT11 variants. Cells were stained for HA-tagged septins (anti-HA antibodies, green) and endogenous septins (anti-SEPT2 antibodies, red). (b) Percentage of HeLa cells displaying aberrant septin bundles after transfection with WT or mutant SEPT6, SEPT7, SEPT9, or SEPT11 (mean from three independent experiments; error bars, SD; ***, P < 0.001). (c) Examples of aberrant septin bundles observed in cells expressing non-SUMOylatable SEPT6, SEPT7, and SEPT11 variants. Cells were stained for HA-tagged septins (anti-HA antibodies). Bars, 5 µm.
