Method of screening for compounds that are suitable for treating a disease or condition caused by or associated with a mutation of CALR, said method comprising the steps:
- (a) providing a compound;
- (b) testing the compound for binding to one or more glycan-, Ca2+—and/or ATP-binding sites of calreticulin, and
- (c) testing the compound for selective inhibition of growth of CALR mutant cells and/or selective cytotoxicity towards CALR mutant cells,
- wherein a compound that (i) binds to one or more glycan-, Ca2+—and/or ATP-binding sites of calreticulin and (ii) selectively inhibits growth of CALR mutant cells and/or exhibits selective cytotoxicity towards CALR mutant cells is identified as a compound that is suitable for treating a disease or condition caused by or associated with a mutation of CALR.
