Mouse Multimerin-1, MMRN1 ELI

Carrier protein for platelet (but not plasma) factor V/Va.

Plays a role in the storage and stabilization of factor V in platelets.

Upon release following platelet activation, may limit platelet and plasma factor Va-dependent thrombin generation.

Ligand for integrin alpha-IIb/beta-3 and integrin alpha-V/beta-3 on activated platelets, and may function as an extracellular matrix or adhesive protein (By similarity).
