Funkcija

uredi

U 2007. istraživači su izvijestili o neočekivanoj ulozi Tel2 u ekspresiji svih proteinskih kinaza povezanih s sisarskim fosfatidilinozitol 3-kinazama (kinaza PIKK). Iako je Tel2 identificiran kao gen pupajućeg kvasca potreban za održavanje dužine telomera, nisu pronašli očiglednu telomernu funkciju sisarskog Tel2. Delecija Tel2 zaustavila je mTOR signalizaciju, ukazujući da Tel2 utiče na PIKK sisara. Tel2 se veže na dio HEAT-ponavljanja segmenata ATM-a i mTOR-a i visoko je konzervirani regulator stabilnosti PIKK-a.[10]
