Summary for Patent: 5,200,509
Title: Human somatomedin carrier protein subunits and process for producing them; recombinant DNA molecules, hosts, processes and human somatomedin carrier protein-like polypeptides
Abstract:This invention relates to polypeptides that are human somatomedin carrier protein subunits and to processes for producing them. The carrier protein subunits bind to human somatomedin-like polypeptides also known as insulin-like growth factors. The process involves preparation from a human serum fraction, Cohn IV-1, by a molecule of various chromatographic steps. This invention also relates to DNA molecules encoding human somatomedin carrier protein-like polypeptides, recombinant DNA molecules, hosts, processes for producing carrier protein-like polypeptides, human somatomedin carrier protein-like polypeptides produced using those molecules, hosts and processes. The invention relates to DNA molecules and their expression in appropriate hosts. The recombinant DNA molecules contain DNA molecules that code for polypeptides which have a biological activity of the human carrier protein or a human carrier protein subunit capable of binding somatomedins. The DNA molecules, recombinant DNA molecules, hosts, and processes of this invention may be used in the production of polypeptides useful in a variety of therapeutic, diagnostic, and other useful applications.

Application Number:07/763,481
Patent Claims: 1. An essentially purified and isolated carrier protein-like polypeptide which:

(a) has a naturally occurring amino acid sequence with the following N-terminal sequence: ##STR4## wherein R is a cysteine or half-cysteine, (b) binds insulin-like growth factor 1 (IGF-1); and

(c) has a molecular weight of about 15,000 to about 30,000 daltos as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis under reducing conditions.
