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

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