摘要

(US20150183844) Composition containing a chimeric neuregulin polypeptides and method of making such polypeptides are disclosed.  The chimeric neuregulin comprises a first moiety of at least 10 amino acids, wherein the first moiety is derived from a first polypeptide; and a second moiety of at least 5 amino acids, wherein the second moiety is derived from a second polypeptide; wherein the first polypeptide is a neuregulin and the chimeric neuregulin exhibits an enhanced binding affinity to integrin, Erb 3, or Erb 4 comparing to that of the first neuregulin.

主权利要求

(US20150183844) 1. A chimeric neuregulin polypeptide having an integrin domain that binds to an integrin and an Erb3/4 binding domain that binds to Erb3 and/or Erb4, said chimeric neuregulin polypeptide comprising: a neuregulin backbone derived from a native neuregulin polypeptide; and a donor fragment of at least one aminoacid, wherein said donor fragment (1) replaces a target fragment in said native neuregulin polypeptide, wherein said donor fragment differs from said target fragment by at least one aminoacid, or (2) is inserted into an insertion site of said neuregulin polypeptide; and wherein said donor fragment forms at least a portion of said integrin binding domain and/or at least a portion of said Erb3/4 binding domain of said chimeric neuregulin polypeptide. 11. A chimeric neuregulin, comprising: a first moiety of at least 10 amino acids, wherein said first moiety is derived from a first polypeptide; and a second moiety of at least 5 amino acids, wherein said second moiety is derived from a second polypeptide; wherein said first polypeptide is a first neuregulin, and wherein said chimeric neuregulin exhibits an enhanced binding affinity to integrin, Erb 3, or Erb 4 comparing to that of said first neuregulin.
