摘要:
The present invention relates to a novel method, based on direct expression cloning, for identifying target proteins capable of binding to and/or serving as substrates for receptor or cytoplasmic tyrosine kinases. The present invention also relates to novel proteins identified using this method, and to methods for identifying compounds that disrupt the interaction of such novel proteins with the receptor or cytoplasmic tyrosine kinases.
摘要:
Methods for treatment, diagnosis, and screening are provided for diseases or conditions characterized by an abnormality in a signal transduction disorder. The signal transduction pathway involves an interaction between a PH domain and a PH domain binding partner.
摘要:
Crystals of the tyrosine kinase domain of cytoplasmic tyrosine kinases and receptor tyrosine kinases that undergo ligand-mediated receptor dimerization are provided. In particular, crystals of a mutant of the tyrosine kinase domain of fibroblast growth factor receptor 1 (FLGK), alone and in complex with a non-hydrolyzable adenosine triphosphate analogue, are provided. Also provided are the high resolution three dimensional structures of crystalline FLGK, both alone and in co-complex with the adenosine triphosphate analogue, as determined by X-ray diffraction.
摘要:
A novel receptor-type protein tyrosine phosphatase-.kappa. (RPTP.kappa.) protein or glycoprotein and the DNA coding therefor is expressed in a wide variety of mammalian tissues. The RPTP.kappa. protein or glycoprotein may be produced by recombinant means. Antibodies to the protein, methods for measuring the quantity of the protein, methods for screening compounds, such as drugs, which can bind to the protein and inhibit or stimulate their enzymatic activity, are provided. Further, methods for inhibiting homophilic binding of Type II RPTP, especially RPTP.kappa. molecules are provided.
摘要:
The present invention concerns methods for diagnosis and treatment of diseases or disorders characterized by abnormal cellular signal transduction involving a newly identified region, herein termed the "APB domain." APB domain binding between proteins is believed to play an important role in signal transduction pathways and, thereby, influence cellular events. Thus, APB mediated activity plays a role in signal transduction pathways and agents modulating APB mediated activity can be used to treat diseases or disorders involving proteins containing APB domains.

A novel receptor-type protein tyrosine phosphatase (RPTP) protein or glycoprotein and the DNA coding therefor is expressed in a wide variety of mammalian tissues. Included in this family of proteins are human RPTP.alpha., human RPTP.beta. and human RPTP.gamma.. The RPTP protein or glycoprotein may be produced by recombinant means. Antibodies to the proteins, methods for measuring the quantity of the proteins, methods for screening compounds, such as drugs, which can bind to the proteins and inhibit or stimulate their activity, are provided.
