Abstract
Growth hormone receptor and growth hormone binding protein are purified enabling amino acid sequence and DNA isolates coding for growth hormone receptor and growth hormone binding protein and methods of obtaining such DNA are provided, together with expression systems for recombinant production of growth hormone receptor and growth hormone binding protein. Therapeutically useful forms of the growth hormone receptor and growth hormone binding protein and anti-receptor antibodies are described.
Claims16
A growth hormone receptor having the ability to bind selectively to growth hormone, said growth hormone receptor comprising an amino acid sequence encoded by a nucleic acid sequence selected from the group consisting of:
- (a) the nucleic acid sequence shown in FIG. 8a;
- (b) the nucleic acid sequence shown in FIG. 8b;
- and
- (c) a nucleic acid sequence which is capable of hybridizing with the nucleic acid sequence of (a) or (b) under low stringency conditions comprising incubating or washing with about 0.15M sodium chloride and 0.015M sodium citrate at about 32.degree.-50.degree. C., or its equivalent,
- wherein said growth hormone receptor is free of proteins normally associated with growth hormone receptor in its in vivo physiological milieu.
A growth hormone binding protein having the ability to bind selectively to growth hormone, said growth hormone binding protein comprising an amino acid sequence selected from the group consisting of:
- (a) the amino acid sequence of from 190 to 246 amino acid residues starting from the N-terminal end of the amino acid sequence shown in FIG. 8a;
- (b) the amino acid sequence of from 190 to 246 amino acid residues starting from the N-terminal end of the amino acid sequence shown in FIG. 8b;
- and
- (c) an amino acid sequence encoded by a nucleic acid sequence which is capable of hybridizing under low stringency conditions with a nucleic acid sequence encoding the amino acid sequence of (a) or (b), said low stringency conditions comprising incubating or washing with about 0.15M sodium chloride and 0.015M sodium citrate at about 32.degree.-50.degree. C., or its equivalent,
- wherein said growth hormone binding protein is free of proteins normally associated with growth hormone binding protein in its in vivo physiological milieu.
A growth hormone binding protein having the ability to bind selectively to growth hormone, said growth hormone binding protein comprising an amino acid sequence selected from the group consisting of:
- (a) the amino acid sequence having at least the first 324 amino acid residues starting from the N-terminal end of the amino acid sequence shown in FIG. 8a;
- (b) the amino acid sequence having at least the first 324 amino acid residues starting from the N-terminal end of the amino acid sequence shown in FIG. 8b;
- and
- (c) an amino acid sequence encoded by a nucleic acid sequence which is capable of hybridizing under low stringency conditions with a nucleic acid sequence encoding the amino acid sequence of (a) or (b), said low stringency conditions comprising incubating or washing with about 0.15M sodium chloride and 0.015M sodium citrate at about 32.degree.-50.degree. C., or its equivalent,
- wherein said growth hormone binding protein is free of proteins normally associated with growth hormone binding protein in its in vivo physiological milieu.
