AGENT TO PROMOTE THE CELL-SURFACE EXPRESSION OR AGENT TO INHIBIT THE CELL-SURFACE EXPRESSION OF PHOSPHATIDYLSERINE, AND AGENT TO INHIBIT THE FORMATION OF LIPID RAFT CLUSTERS

摘要

Provided are: an agent that promotes the cell surface expression of PS, and that includes a peptide containing the EGF1 domain of factor IX or a peptide containing the EGF3 domain of endothelial cell-1 protein; an agent that inhibits the cell surface expression of PS, and that contains a peptide that includes a portion obtained by removing the trypsin domain (heavy chain) portion and the light chain portion from the full length of factor IX; and an agent for inhibiting the formation of lipid raft clusters, and that contains a peptide that includes a portion obtained by removing the trypsin domain (heavy chain) portion and the light chain portion from the full length of factor IX.
