Abstract
The present invention provides a mutant protein which has the same amino acid sequence of a wild type PF4 monomer except that (i) at least one amino acid of the wild type PF4 monomer has been deleted, (ii) at least one amino acid of the wild type PF4 monomer has been replaced by another amino acid, or (iii) a combination of such changes has been made. The present invention also provides methods of treating or reducing the likelihood of HIT, treating angiogenesis, treating abnormal cell growth, or affecting coagulation pathologies that lead to thrombus formation, by administering such mutant proteins to a patient.
