  • Patent number: 9012159
    Abstract: A method for identifying a compound which modulates the activity of acyl-coA: diacylglycerol acyltransferase comprises the steps of contacting a stable isotope labeled fatty acid with cells in either presence or absence of the compound, extracting the cells with isopropyl alcohol, and determining the level of a stable isotope labeled triglyceride in the presence or absence of the compound; wherein a change in the level of the stable isotope labeled triglyceride indicates that the compound modulates the DGAT activity.
    Type: Grant
    Filed: January 7, 2010
    Date of Patent: April 21, 2015
    Assignee: Janssen Research & Development, LLC
    Inventors: Jian-Shen Qi, Wensheng Lang, Margery A. Connelly

  • Patent number: 7452708
    Abstract: A novel human cDNA, termed PRSS11-L, was isolated which encodes a polypeptide that belongs to the S2/HtrA serine protease family. The PRSS11-L mRNA is widely expressed in several tissues throughout the body by multi-tissue Northern blotting. The full-length PRSS11-L cDNA, was cloned, expressed and purified. Proteolytic activity was demonstrated using the protein substrate casein. The isolated nucleic acid or polypeptide molecule of the invention can be used in detection assays, gene therapy, and screening assays.

  • Patent number: 7070977
    Abstract: Polypeptides corresponding to a novel S1 serine protease family member, termed protease D-G, and nucleic acids encoding them are described. The materials may be used, for example, in screening assays to identify protease D-G modulators and in methods for diagnosing or treating conditions associated with aberrant protease D-G activity.

  • Publication number: 20040146981
    Abstract: Here we describe the molecular identification of a cDNA encoding a novel serine protease we have termed D-G. The deduced amino acid sequence, and it's alignment with other well characterized serine proteases clearly indicates that it is a member of the S1 serine protease family. We have found that the protease D-G mRNA is widely expressed in several tissues throughout the body including epidermis, fibroblasts, keratinocytes, colon, small intestine, stomach, lung, kidney, bone marrow, lymph node, thymus, ovary, prostate, uterus and spinal cord. Interestingly, this protease contains a hydrophobic stretch of amino acids which is a putative transmembrane near the NH2-terminus. Thus, this serine protease is thought to be synthesized as a type II integral protein.
