FOXP1
Protein P1 viljuškaste kutije jest protein koji je kod ljudi kodiran genom FOXP1 sa hromosoma 3. FOXP1 je neophodan za pravilan razvoj mozga, srca i pluća kod sisara. Član je velike porodice transkripcijskih faktora FOX.

Funkcija
urediOvaj gen pripada potporodici P porodice transkripcionih faktora viljuškaste kutije (FOX). Faktori transkripcije ove kutije imaju važnu ulogu u regulaciji transkripcije gena specifične za tkivo i tip ćelije tokom razvoja i odrasle dobi. P1 protein viljuškaste kutije sadrži i DNK-vezujući domen – i domene za vezivanje protein-protein. Ovaj gen može djelovati kao tumorski supresor jer se gubi u nekoliko tipova tumora i mapira na hromozomskoj regiji (3p14.1) za koju se navodi da sadrži tumor supresorski gen(e). Alternativna prerada rezultira višestrukim varijantama transkripta koje kodiraju različite izoforme.[4]
Foxp1 je faktor transkripcije; konkretno, to je transkripcijski represor. Geni FOX-a su dio porodičnog domena koji se vezuje za DNK. Ovaj domen se vezuje za sekvence u promotorima i pojačivačima mnogih gena. Foxp1 regulira niz važnih aspekata razvoja, uključujući razvoj tkiva: pluća, mozga, timusa i srca. U srcu Foxp1 ima tri vitalne uloge, koje uključuju regulaciju sazrijevanja i proliferacije kardiomiocita, odvajanje odlivnog trakta plućne arterije i aorte i ekspresiju Sox4 u holsterima i miokardu. Foxp1 je također važan gen u razvoju mišića i epitela jednjaka. Foxp1 je takođe važan regulator morfogeneze plućnih disajnih puteva. Embrioni Foxp1 nokaut-miševa pokazuju ozbiljne defekte u srčanoj morfogenezi. Neki od ovih defekata uključuju greške sazrijevanja i proliferacije miocita koji uzrokuju tanku ventrikularnu kompaktnu zonu miokarda, nerazdvajanje plućne arterije i aorte i povećanje proliferacije kardiomiocita i defektnu diferencijaciju. Ovi defekti, uzrokovani inaktivacijom Foxp1, dovode do smrti fetusa. Poremećaji FoxP1 su identificirani kod vrlo rijetkih ljudskih pacijenata i – slično kao i FoxP2 – dovode do kognitivne disfunkcije, uključujući intelektualnu invalidnost i poremećaj iz autističkog spektra, zajedno s oštećenjem jezika.[5]
Pokazalo se da (ESC)-specifična izoforma FOXP1 embrionske matične ćelije stimulira ekspresiju gena transkripcijskik faktora potrebnih za pluripotencijju, uključujući OCT4, NANOG, NR5A2 i GDF3, dok istovremeno potiskuju gene potrebne za diferencijaciju ESC-a. Ova izoforma također promovira održavanje pluripotentnosti ESC i doprinosi efikasnom reprogramiranju somatskih ćelija u inducirane pluripotentne matične ćelije. Ovi rezultati otkrivaju ključnu ulogu za događanje alternativne prerade u regulaciji pluripotencije putem kontrole kritičnih ESC-specifičnih transkripcijskih programa.[6]
