Switch #:
SWTI000234
Switch type:
Binary
Switch subtype:
Allostery

Description:
Binding of 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate to the AP-2 complex alpha, beta and mu subunits exposes a binding site on the AP-2 complex subunit sigma (AP2S1) subunit for recruitment of HLA class II histocompatibility antigen gamma chain (CD74) via an endocytosis motif.

Participants:
(1) HLA class II histocompatibility antigen gamma chain (CD74)
(2) AP-2 complex subunit sigma (AP2S1)
