Identifying new drug targets by mapping disease-associated genes is made difficult by the fact that more than one gene might act synergistically to cause the condition.

A new approach, genome hybrid identity profiling, identifies DNA regions that are ‘identical by descent’ for the entire genomes of two related individuals. Isolating disease-associated genes in this way gives researchers a fast, precise way of identifying potential drug targets for treatment of complex diseases.</p></div>","PeriodicalId":101208,"journal":{"name":"TARGETS","volume":"2 2","pages":"Pages 65-68"},"PeriodicalIF":0.0,"publicationDate":"2003-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1477-3627(03)02293-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86655464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are thought to be more than 500 therapeutically relevant GPCRs out of a total of over 700 identified to date, although only one, rhodopsin, has been the subject of a full 3D X-ray crystallography study. Two structurally related proteins, bacteriorhodopsin and sensory rhodopsin, which are not GPCRs but are part of the seven-helix membrane receptor family, have also been the subject of X-ray crystallographic studies and have been used in GPCR modeling studies. The significant differences between these rhodopsin structures, the relatively low sequence homology between individual GPCRs, and some difficulties in rationalizing point-mutation data suggests that homology-based molecular modeling alone will not provide the accurate structural information on individual receptors required for ligand design and <em>in silico</em> screening. In the absence of such structural information, several approaches can be used to assist in the discovery of ligands.</p></div>","PeriodicalId":101208,"journal":{"name":"TARGETS","volume":"2 1","pages":"Pages 19-25"},"PeriodicalIF":0.0,"publicationDate":"2003-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1477-3627(02)02283-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75333178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selection of targets to progress to lead identification, the efficiency of assay development, and the analysis of results from compound testing all benefit from the availability of high-quality target information and appropriate utilization tools during lead discovery. Specifically, associating target information with other information produced during lead generation enables: the assessment of emerging targets with respect to their chemical tractability; the grouping of data from similar targets to aid in the identification of potential lead compounds and ‘privileged structures’; and the results from compound testing to be analysed in the context of their biological target.
