Abstract
A mutant erythropoietin receptor of mammalian origin which is hypersensitive to erythropoietin, DNA encoding the mutant erythropoietin receptor and uses therefor. An assay method for identifying compounds which mimic erythropoietin is also disclosed.
Claims3
DNA encoding a mutant erythropoietin receptor having an alteration of the wild-type murine erythropoietin receptor selected from the group consisting of:
- a) replacement of the C-terminal 42 amino acids with alanine-leucine;
- b) replacement of the arginine at codon 129 with cysteine;
- and
- c) replacement of the C-terminal 42 amino acids with alanine-leucine and replacement of the arginine at codon 129 with cysteine.

- a) replacement of the C-terminal 42 amino acids with alanine-leucine;
- b) replacement of the arginine at codon 129 with cysteine;
- and
- c) replacement of the C-terminal 42 amino acids with alanine-leucine and replacement of the arginine at codon 129 with cysteine.
