Funkcija
Ovaj gen kodira člana gelsolin /vilin porodice aktin -regulatornih proteina.[ 9] Kodirani protein reverzibilno blokira bodljikave krajeve F-aktinskih filamenata na Ca2+ski i fosfoinozitidno -regulisan način, ali ne prekida prethodno formirane aktinske filamente. Pokrivanjem bodljikavih krajeva aktinskih filamenata, kodirani protein doprinosi kontroli pokretljivosti zasnovanoj na aktinu u nemišićnim ćelijama. Uočene su alternativno prerađene varijanta transkripta , ali nisu u potpunosti opisane.[ 7]
