VASCULAR ADHESIVE MOLECULES AND MODULATION OF THEIR FUNCTIONS Russian patent published in 2005 - IPC

FIELD: biotechnology, medicine, proteins.

SUBSTANCE: invention describes new polypeptide in isolated form relating to subfamily of superfamily human immunoglobulins (Ig-Sf). This polypeptide shows at least 70% of homology level with amino acid sequence of murine molecules CRAM-1 or CRAM-2 regulated by the confluence of adhesive (figures 3, 6 are represented in the claim). Also, invention relates to antibodies showing specificity with respect to the polypeptide. Antibodies and soluble polypeptide can be used for treatment of inflammation and tumors. Invention describes polynucleotide or oligonucleotide encoding the full-size polypeptide or its moiety and represents primer, probe, anti-sense RNA and shows the nucleotide sequence that is identical conceptually with human CRAM-1. Invention provides preparing new adhesive proteins from superfamily Ig-Sf that are regulated at the transcription level in endothelium by effect of tumors. Invention can be used for treatment of different diseases, in particular, inflammatory responses.

EFFECT: valuable medicinal properties of polypeptide.
