Abstract excerpt
The Kell blood group protein is a metalloendopeptidase that preferentially cleaves a Trp(21)-Ile(22) bond of big endothelin-3 producing bioactive endothelin-3. Kell is a polymorphic protein, and 25 different phenotypes, because of point mutations resulting in single amino acid substitutions, have been described. It was recently reported that a recombinant form of KEL1 (K, K1) phenotype, expressed in K562 and...
