This entry represents the rod domain of the bacterial equivalent to Intermediate Filament proteins, named crescentin (CreS), whose cytoskeletal function is required for the vibrioid and helical shapes of Caulobacter crescentus [1]. Without crescentin, the cells adopt a straight-rod morphology. Crescentin has characteristic features of IF proteins including the ability to assemble into filaments in vitro without energy or cofactor requirements. In vivo, crescentin forms a helical structure that colocalizes with the inner cell curvatures beneath the cytoplasmic membrane [1]. This domain consist of a long coiled coil without linkers that disrupt the overall alpha-helical structure, unlike in eukaryotic IF proteins [4].
