===Septins===
{{main|Septin}}

Septins are a group of the highly conserved [[Guanosine triphosphate|GTP]] binding proteins found in [[eukaryotes]]. Different septins form [[protein complex]]es with each other. These can assemble to filaments and rings. Therefore, septins can be considered part of the cytoskeleton.<ref name="Mostowy2012">{{cite journal | vauthors = Mostowy S, Cossart P | title = Septins: the fourth component of the cytoskeleton | journal = Nature Reviews.

Recent research in human cells suggests that septins build cages around bacterial pathogens, immobilizing the harmful microbes and preventing them from invading other cells.<ref name=Mascarelli_2011>{{cite journal | vauthors = Mascarelli A | title = Septin proteins take bacterial prisoners: A cellular defence against microbial pathogens holds therapeutic potential | journal = Nature |date=December 2011 | doi = 10.1038/nature.2011.9540 | s2cid = 85080734 | doi-access = free }}</ref>
