Abstract:
PROBLEM TO BE SOLVED: To provide an isolated polypeptide containing the extracellular domain of a hematopoietin receptor. SOLUTION: The isolated polypeptide containing an amino acid sequence represented by a specific sequence residue. The polypeptide is encoded in a new gene which contains two FN3 domains containing the characteristic [WS box] of a hematopoietin family gene obtained by isolating a cDNA clone from a human fetal liver cDNA library and then determining its DNA sequence.

Abstract:
The present invention relates to variant forms of the receptor for the obese gene product. In particular, the invention relates to methods of detecting receptor variants in the reproductive organs for the diagnosis of the cause of infertility. In addition, it relates to methods of inhibiting or down-regulating expression of defective variants in cells to augment their responsiveness to regulation by leptin as well as methods of using compounds to directly activate signal transduction pathways associated with this ligand-receptor system to improve fertility.

Abstract:
The present invention relates to a novel member of the hematopoietin recepto r family, herein referred to as Hu-B1.219. In particular , the invention relates to nucleotide sequences and expression vectors encodin g Hu-B1.219 gene product. Genetically engineered host ce lls that express the Hu-B1.219 coding sequence may be used to evaluate and scree n for ligands or drugs involved in Hu-B1.219 interaction and regulation. Since Hu-B1.219 expression has been detected in certain huma n fetal tissues and cancer cells, molecular probes desig ned from its nucleotide sequence may be useful for prenatal testing and cancer d iagnosis.
Abstract:
Polymorphic sites in the region surrounding the HFE gene are provided. These polymorphisms are useful as surrogate markers in diagnostic assays for hemochromatosis. Additionally, a fine structure map of the 1 megabase region surrounding the HFE gene is provided, along with 235 kb of DNA sequence and 8 loci corresponding to candidate genes within the 1 megabase region, and in the purification of related proteins.
