NEW G-PROTEIN COUPLED RECEPTOR LUSTR2 AND USES THEREOF

摘要

Polynucleotide sequence for novel G-protein coupled receptor LUSTR2 and uses thereof. The present invention is directed to a polynucleotide sequence of a novel G-Protein Coupled Receptor LUSTR2. More particularly, the present invention provides a polynucleotide sequence comprising the nucleic acid sequence SEQ ID NO: 1 or nucleic acid sequences that hybridize to SEQ ID NO: 1 or its complimentary strand having at least 40% sequence identity. Preferably, the hybridizing nucleic acid sequence should hybridize under stringent conditions and in particular have 85% sequence identity, more preferably 90% sequence identity, and most preferably 95% sequence identity. The invention also provides the human LUSTR2 associated with the haemaotological, peripheral and central nervous system, COPD, asthma, genito-urological, metabolic diseases and pancreas and heart disorders as a result of relative quantification of the mRNA distribution in different human tissues by expression profiling. The invention also provides assays for the identification of compounds useful for the modulation of hematological, peripheral and central nervous system, COPD, asthma, genito-urological, metabolic diseases and pancreas and heart disorders for treating or preventing hematological, peripheral and central nervous system, COPD, asthma, genito-urological, metabolic diseases and pancreas and heart disorders associated with expression of the LUSTR2. The methods of the invention involve cell-free and cell-based assays that identify compounds which bind to and/or activate or inhibit the activity of LUSTR2, a G protein coupled receptor, followed by an in vivo assay of the effect of the compound on hematological, peripheral and central nervous system, COPD, asthma, genito-urological, metabolic diseases and pancreas and heart disorders. The invention also features compounds which bind to and/or activate or inhibit the activity of LUSTR2 as well as pharmaceutical compositions comprising such compounds.
