87 results about "Serpin" patented technology

Serpins are a superfamily of proteins with similar structures that were first identified for their protease inhibition activity and are found in all kingdoms of life. The acronym serpin was originally coined because the first serpins to be identified act on chymotrypsin-like serine proteases (serine protease inhibitors). They are notable for their unusual mechanism of action, in which they irreversibly inhibit their target protease by undergoing a large conformational change to disrupt its active site. This contrasts with the more common competitive mechanism for protease inhibitors that bind to and block access to the protease active site.

Correction of alpha-1-antitrypsin genetic defects using spliceosome mediated RNA trans splicing

InactiveUS20060234247A1Reduce lungReduce liver pathologySugar derivativesMicrobiological testing/measurementDiseaseRNA Trans-Splicing
The present invention provides methods and compositions for generating novel nucleic acid molecules through targeted spliceosomal mediated RNA trans-splicing. The compositions of the invention include pre-trans-splicing molecules (PTMs) designed to interact with a SERPINA1 target precursor messenger RNA molecule (target pre-mRNA) and mediate a trans-splicing reaction resulting in the generation of a novel chimeric RNA molecule (chimeric RNA). In particular, the PTMs of the present invention include those genetically engineered to interact with SERPINA1 target pre-mRNA so as to result in correction of SERPINA1 genetic defects responsible for AAT deficiency. The PTMs of the invention may also comprise sequences that are processed out of the PTM to yield duplex siRNA molecules directed specifically to mutant SERPIN A1 mRNAs. Such duplexed siRNAs are designed to reduce the accumulation of toxic AAT protein in liver cells. The methods and compositions of the present invention can be used in gene therapy for correction of SERPINA1 disorders such as AAT deficiency.
