Factor na fassarar Gal4

Ma'anar rubutun Gal4 shine ingantaccen mai sarrafa bayanin kwayar halittar kwayoyin halittar galactose.  Wannan furotin yana wakiltar babban dangin fungal na abubuwan rubutu, dangin Gal4, wanda ya haɗa da mambobi sama da 50 a cikin yisti Saccharomyces cerevisiae misali Oaf1, Pip2, Pdr1, Pdr3, Leu3. 

Gal4 yana gane kwayoyin halitta tare da UAS G, jerin kunnawa na sama, kuma yana kunna su. A cikin sel yisti, manyan makasudin sune GAL1 ( galactose ), GAL10 ( UDP-glucose 4-epimerase ), da GAL7 ( galactose-1-phosphate uridylyltransferase ), enzymes uku da ake buƙata don metabolism na galactose. Wannan ɗaure kuma ya tabbatar da amfani wajen gina tsarin GAL4/UAS, dabara don sarrafa magana a cikin kwari.  A cikin yisti, Gal80 ne ke matsawa Gal4 ta tsohuwa, kuma yana kunna shi a gaban galactose yayin da Gal3 ke ɗaure Gal80.
