POLYPEPTIDE POSSESSING CAPACITY FOR BINDING WITH INTRACELLULAR DOMAIN p-55 OF TNF-RECEPTOR, DNA MOLECULE ENCODING THIS POLYPEPTIDE, EXPRESSION VECTOR AND METHOD FOR PREPARING POLYPEPTIDE Russian patent published in 2006 - IPC C12N15/12 C07K14/435 C12P21/02 

Abstract RU 2273664 C2

FIELD: molecular biology, genetic engineering, polypeptides, medicine.

SUBSTANCE: in using the double-hybrid yeast system DNA sequences encoding polypeptides (55.1 and 55.3) have been found that elicit ability for binding with intracellular domain p-55 (p-55IC) of TNF-receptor. It has been established that these polypeptides represent fragments of amino acid sequences p-55IC, respectively, from 338 to 426 and from 277 to 426 residues. As result of insertion of DNA fragments with a sequence encoding polypeptide 55.1 or 55.3 into the structure of expressing vector and transformation suitable host-cells by this vector recombinant form of indicated polypeptides have been prepared. Using this invention provides the possibility for modulating the function of intact p-55 of TNF-receptor. Invention can be used in medicine in treatment of diseases associated with transfer of TNF-signal.

EFFECT: improved preparing method and valuable properties of polypeptide.
