NCIt definition : Multimerin-1 (1228 aa, 138 kDa) is encoded by the human MMRN1 gene. This protein
is involved in stabilization of platelet-bound factor V/Va.;
NCIt note : Multimerin-1 deficiency is associated with Quebec platelet disorder (factor V Quebec).
This deficiency is presumably caused by excessive levels of platelet protein degradation
by activated plasmin, which results from the overexpression of urokinase-type plasminogen
activator (PLAU) in alpha granules. (OMIM);
