Funkcija
urediOvaj gen kodira citoplazmatski protein uključen u regulaciju kontrolne tačke mitotskog vretena, regulatorni put koji prati segregaciju hromozoma tokom ćelijske diobe kako bi se osigurala pravilna distribucija hromosoma u ćeliji kćeri. Protein je fosforiliran u mitozi i kao odgovor na aktivaciju kontrolne tačke vretena i nestaje kada ćelije pređu u G-fazu. Stupa u interakciju sa mitotskim regulatorom, a njegova ekspresija je potrebna za efikasno aktiviranje kontrolne tačke vretena.
Predlaže se da se regulira aktivnost Cdc2 kinaze tokom zaustavljanja kontrolne tačke vretena. Hromosomske delecije koje spajaju ovaj gen i susjedni lokus obično se javljaju u T-ćelijskoj leukemiji, a smatra se da nastaju nelegitimnim događajima rekombinacije. Za ovaj gen pronađene su višestruke varijante transkripta koje kodiraju različite izoforme.[6]
Homozigotne mutacije u STIL genu uzrokuju primarnu mikrocefaliju (mali mozak) kod ljudi.
