POLYPEPTIDES DERIVED FROM TRYPTOPHANYL-TRNA-SYNTHETASE AND USES THEREOF IN CONTROLLING OF VASCULARISATION Russian patent published in 2007 - IPC C07K14/00 C07K2/00 C12N1/20 C12N15/11 C12N15/63 C12N5/00 A61K38/16 A61P27/02 

FIELD: biotechnology.

SUBSTANCE: invention relates to water soluble polypeptides (SEQ ID NO.12) and (SEQ ID NO.7), derived from full-length tryptophanyl-tRNA-synthetase and having angiostatic activity in relation to eye neovasculatisation. Also disclosed are polynucleotides, encoding truncated polypeptide forms (SEQ ID NO.12) and (SEQ ID NO.7), and E.coli cell, expressing abovementioned polypeptides. Said polypeptides are useful in injecting angiostatic composition and kit for inhibiting of eye neovasculatisation.

EFFECT: polypeptides having non-immunogenic angiogenic properties.
