Switch #:
SWTI000298
Switch type:
Pre-assembly
Switch subtype:
Composite binding site formation

Description:
Binding of EGF-like repeat and discoidin I-like domain-containing protein 3 (EDIL3) to integrin receptors depends on pre-assembly of Integrin alpha-V (ITGAV)-Integrin beta-3 (ITGB3) heterodimers, since association of the integrin alpha and beta subunits results in the formation of a composite binding site for the RGD motif in the ligand.

Participants:
(1) Integrin alpha-V (ITGAV)
(2) Integrin beta-3 (ITGB3)
(3) EGF-like repeat and discoidin I-like domain-containing protein 3 (EDIL3)

Interactions
This is a sequential switch. The interactions in this switch take place in a defined order. The order is defined by numbers to the left of each interaction. More than one interaction can occur in each step, these interactions occur independently but are necessary for future step
2Interaction #2 EDIL3 - Interaction #1 ITGAV - ITGB3

Requires Interaction #1 ITGAV - ITGB3

Interfaces
(3) LIG_RGD motif (96RGD98) in EGF-like repeat and discoidin I-like domain-containing protein 3 (EDIL3)
(4) Interaction #1 ITGAV - ITGB3
