plasma membrane

basic FUNCTION

GP1b complex involved in adhesion of a damaged vessel wall to the extra cellular matrix

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

component of the GP1b complex (von Willebrand receptor) where it is linked to GP1BB through disulfide bonds non covalently to GP6 and GP9

protein	binding VWF through its domain A1 and A3
	interacting with FLNA

cell & other

REGULATION

Other

adhesive function is regulated by its anchorage to the membrane skeleton through a specific interaction with filamin A
