Publication number: 20030119002Abstract: Methods are described for detecting protein-protein interactions, among two populations of proteins, each having a complexity of at least 1,000. For example, proteins are fused either to the DNA-binding domain of a transcriptional activator or to the activation domain of a transcriptional activator. Two yeast strains, of the opposite mating type and carrying one type each of the fusion proteins are mated together. Productive interactions between the two halves due to protein-protein interactions lead to the reconstitution of the transcriptional activator, which in turn leads to the activation of a reporter gene containing a binding site for the DNA-binding domain. This analysis can be carried out for two or more populations of proteins.Type: ApplicationFiled: November 15, 2001Publication date: June 26, 2003Applicant: CuraGen Corp.Inventors: Krishnan Nandabalan, Jonathan Marc Rothberg

Publication number: 20030003463Abstract: This invention includes methods for identifying nucleic acids in a sample of nucleic acids by observing sequence sets present in the nucleic acids of the sample and then identifying those sequences in a nucleic acid sequence database having the sequence sets observed. In a preferred embodiment, a sequence set consists of two primary subsequences and an additional subsequence having determined mutual relationships. The methods include those for observing the sequence sets and those for performing sequence database searches. This invention also includes devices for recognizing in parallel the additional subsequences in a sample of as well as methods for the use of these devices. In a preferred embodiment, the devices include probes bound to a planar surface that recognize additional subsequence by hybridization, and the methods of use include features to improve the specificity and reproducibility of this hybridization.Type: ApplicationFiled: November 21, 2001Publication date: January 2, 2003Applicant: CuraGen CorporationInventors: Jonathan Marc Rothberg, Girish N.

Patent number: 6453245Abstract: This invention provides methods by which biologically derived DNA sequences in a mixed sample or in an arrayed single sequence clone can be determined and classified without sequencing. The methods make use of information on the presence of carefully chosen target subsequences, typically of length from 4 to 8 base pairs, and preferably the length between target subsequences in a sample DNA sequence together with DNA sequence databases containing lists of sequences likely to be present in the sample to determine a sample sequence. The preferred method uses restriction endonucleases to recognize target subsequences and cut the sample sequence. Then carefully chosen recognition moieties are ligated to the cut fragments, the fragments amplified, and the experimental observation made. Polymerase chain reaction (PCR) is the preferred method of amplification.Type: GrantFiled: January 10, 2001Date of Patent: September 17, 2002Assignee: CuraGen CorporationInventors: Jonathan Marc Rothberg, Michael W.

Patent number: 6410239Abstract: Methods are described for detecting protein-protein interactions, among two populations of proteins, each having a complexity of at least 100. Encoded proteins are fused either to the DNA-binding domain of a transcriptional activator or to the activation domain of a transcriptional activator. Two yeast strains, of the opposite mating type and carrying one type each of the fusion proteins are mated together. Productive interactions between the two halves due to protein-protein interactions lead to the reconstitution of the transcriptional activator, which in turn leads to the activation of a reporter gene containing a binding site for the DNA-binding domain. This analysis can be carried out for two or more populations of proteins.Type: GrantFiled: December 14, 1999Date of Patent: June 25, 2002Assignee: CuraGen CorporationInventors: Krishnan Nandabalan, Jonathan Marc Rothberg, Meijia Yang, James Robert Knight, Theodore Samuel Kalbfleisch

Publication number: 20020009741Abstract: This invention is an integrated instrument for the high-capacity electrophoretic analysis of biopolymer samples. It comprises a specialized high-voltage, electrophoretic module in which the migration lanes are formed between a bottom plate and a plurality of etched grooves in a top plate, the module permitting concurrent separation of 80 or more separate samples. In thermal contact with the bottom plate is a thermal control module incorporating a plurality of Peltier heat transfer devices for the control of temperature and gradients in the electrophoretic medium. Fragments are detected by a transmission imaging spectrograph which simultaneously spatially focuses and spectrally resolves the detection region of all the migration lanes. The spectrograph comprises a transmission dispersion element and a CCD array to detect signals. Signal analysis comprises the steps of noise filtering, comparison in a configuration space with signal prototypes, and selection of the best prototype.Type: ApplicationFiled: April 17, 2001Publication date: January 24, 2002Applicant: CuraGen CorporationInventors: John W.

Patent number: 6341256Abstract: In a specific embodiment, this invention includes a method for determining an accurate, consensus pharmacophore structure shared by compounds that bind selectively to a target molecule. Optionally, the method begins with screening a diversity library against the target molecule of interest to pick the selectively binding members. Next the structure of the selected members is examined and a candidate pharmacophore responsible for the binding to the target molecule is determined. Next, preferably by REDOR nuclear magnetic resonance, several highly accurate interatomic distances are determined in certain of the selected members which are related to the candidate pharmacophore. A highly accurate consensus, configurational bias, Monte Carlo method determination of the structure of the candidate pharmacophore is made using the structure of the selected members and incorporating as constraints the shared candidate pharmacophore and the several measured distances.Type: GrantFiled: March 31, 1995Date of Patent: January 22, 2002Assignee: CuraGen CorporationInventors: Michael W.
