AP2M1 (AP-2 kompleks podjedinica mi) je protein koji je kod ljudi kodiran AP2M1 genom.[1]

Ovaj gen kodira podjedinicu heterotetramernog proteinskog kompleksa 2 (AP2). Ovaj protein je neophodan za aktivnost vakuolarnih ATPaza, koje su odgovorne za pumpanje protona do kojeg dolazi tokom acidifikacije endozoma i lizozoma. On takođe učestvuje u regulaciji intraćelijskog prenosa i funkcije CTLA-4 proteina. Postoje dve transkriptne varijante koje kodiraju različite izoforme.[2]

Interakcije[uredi - уреди]

Za AP2M1 je pokazano da interaguje sa CTLA-4[3][4] i alfa-1B adrenergičkim receptorom.[5]
