Funkcija

DAP-4 je gvanilat-kinaza povezana s membranom koja se nalazi u postsinapsnoj gustoći u nervnih ćelija. To je signalna molekula, koja može stupiti u interakciju s kalijevim kanalom i receptorima, kao i drugim signalnim molekulama. DAP-4 može komunicirati sa PSD-95 preko svog domena gvanilat-kinaze i može biti uključen u klasteriranje PSD-95, u regiji postsinapsne gustoće. Kodirani protein je jedan od najmanje četiri slična proteina koja su pronađena. Za ovaj gen pronađene su alternativno prerađene varijante transkripata, koje kodiraju različite izoforme.
