Isolated nucleic acid encoding Hu-B1.219, a novel human hematopoietin receptor

摘要

The present invention relates to a novel member of the hematopoietin receptor family; herein referred to as Hu-B1.219. In particular, the invention relates to nucleotide sequences and expression vectors encoding Hu-B1.219 gene product Genetically engineered host cells that express the Hu-B1.219 coding sequence may be used to evaluate and screen for ligands or drugs involved in Hu-B1.219 interaction and regulation. Since Hu-B1.219 expression has been detected in certain human fetal tissues and cancer cells, molecular probes designed from its nucleotide sequence may be useful for prenatal testing and cancer diagnosis.
