This family includes the tubulin alpha, beta and gamma chains, as well as the bacterial FtsZ family of proteins. Members of this family are involved in polymer formation. FtsZ is the polymer-forming protein of bacterial cell division. It is part of a ring in the middle of the dividing cell that is required for constriction of cell membrane and cell envelope to yield two daughter cells. FtsZ and tubulin are GTPases. FtsZ can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in eubacteria and archaea. Tubulin is the major component of microtubules.	Domain

CetZ proteins are related with Tubulin/FtsZ, and has the Tubulin GTPase domain (Pfam:PF00091) at the N-termi ...	This is the C-terminal domain CetZ proteins, which are tubulin-like proteins involved in control cell shape in Archaea and some bacteria [1]. CetZ proteins are related with Tubulin/FtsZ, and has the Tubulin GTPase domain (Pfam:PF00091) at the N-terminal. This domain has a two-layer alpha-beta structure with an alpha-helical extension.
