AAK1 is a serine-threonine kinase that phosphorylates T156 of the AP2 mu2 subunit (Olusanya et al, 2001; Conner et al, 2002; Conner et al, 2003). This phosphorylation is thought to stabilize the open conformation of the AP-2 complex, exposing the cargo-binding sites and promoting cargo capture (Ricotta et al, 2002). AAK1 kinase activity is stimulated by interaction with clathrin (Conner et al, 2003; Henderson et al, 2007).
