CENPF
Centromerni protein F jest protein koji je kod ljudi kodiran genom CENPF sa hromosoma 1.[5][6][7] Uključen je u segregaciju hromosoma tokom ćelijske diobe. Također ima ulogu u orijentaciji mikrotubula u formiranju ćelijskih cilija.[8][9]

Funkcija
urediCENPF je dio jedarnog matriksa tokom G2-faze ćelijskog ciklusa (faza brze sinteze proteina u pripremi za mitozu). U kasnoj G2, protein čini dio kinetohorskog, proteinskog kompleksa u obliku diska koji omogućava centromerama dviju sestrinskih hromatida da se veže za mikrotubule (formirajući aparat vretena) kako bi ih mikrotubule razdvojile u procesu ćelijske diobe. Ostaje dio kinetohora tokom rane anafaze (faza podjele hromosoma). U kasnoj anafazi, CENPF odlazi na srednju zonu vretena, a u telofazi (faza dijeljenja ćelija) sdolazi na međućelijski most. Smatra se da se naknadno degradira. Mutacije u "CENPF" dovode do poremećene diobe ćelija tokom ranog razvoja. Utvrđeno je da mitozaa traje duže kada je gen mutiran.[8][9]
Mikrotubule su proteinske strukture koje su dio citoskeleta i neophodne su kako bi ćelije imale različite, složene oblike i sposobnost migraciona. Njih pravi centrosom, koji sadrži par cilindričnih centriola pod pravim uglom jedna u odnosu na drugu. Prije podjele, CENPF se lokalizira na kraju jedne od centriola (matične centriole), kako bi ispravno orijentirao mikrotubule u formiranju tankih ćelijskih projekcija koje se nazivaju cilije. Većina cilija su primarne cilije, koje su uključene u ćelijsku signalizaciju da bi pokrenule migraciju, diobu ili diferencijaciju. Mutacije u "CENPF" remete ovu sposobnost formiranja cilija; utvrđeno je da su cilije malobrbrojnije i kraće kada je gen mutiran.[8][11]
Smatra se da CENPF formira ili homodimer ili heterodimer.
Klinički značaj
urediMutacije u obje kopije CENPF uzrokuju Strømmeov sindrom, karakteriziran mikrocefalijom, abnormalnostima očne jabučice i jejunumskom atrezijom.[9] Autoantitijela protiv CENPF-a pronađena bolesti u kod pacijenata s rakom ili bolesti reakcije transplantata protiv domaćina.[7]
