摘要:
A novel receptor-type protein tyrosine phosphatase-.beta. (RPTP.beta.) protein or glycoprotein is disclosed. This protein is naturally expressed in the brain and in neural cell lines.
摘要:
The present invention features a method for treatment of an organism having a disease or condition characterized by an abnormality in a signal transduction pathway, wherein the signal transduction pathway includes a rdgB protein. The invention also features methods for diagnosing such diseases and for screening for agents that will be useful in treating such diseases. The invention also features purified and/or isolated nucleic acid encoding a rdgB protein.
摘要:
The present invention relates to compositions and methods for the prevention and treatment of cell proliferative disorders wherein a protein tyrosine kinase or protein tyrosine phosphatase capable of complexing with a member of the SH2- and/or SH3-containing family of adaptor proteins is involved. This invention is based, in part, on the surprising discovery that the adaptor protein, GRB-2, binds the intracellular BCR-ABL tyrosine kinase product in vivo and is necessary for the activation of the oncogenic potential of the BCR/ABL product. The present invention further relates to protein tyrosine kinase/adaptor protein complexes and the uses of these complexes for the identification of agents capable of decreasing or inhibiting the interaction between the members of such complexes.
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:
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:
Provided herein, in one aspect, are antibodies that immunospecifically bind to a human KIT antigen comprising the fourth and/or fifth extracellular Ig-like domains (that is, D4 and/or D5 domains), polynucleotides comprising nucleotide sequences encoding such antibodies, and expression vectors and host cells for producing such antibodies. The antibodies can inhibit KIT activity, such as ligand-induced receptor phosphorylation. Also provided herein are kits and pharmaceutical compositions comprising antibodies that specifically bind to a KIT antigen, as well as methods of treating or managing a KIT-mediated disorder or disease and methods of diagnosing a KIT-mediated disorder or disease using the antibodies described herein.
摘要:
The determination and use of three dimensional structures of receptor protein tyrosine kinases and/or their ligands are described. One particular group of such structures includes three dimensional structures of the extracellular domain of RPTKs. The three dimensional structures of RPTKs can faciliate the design and identification of modulators of RPTK function. Other such structures can include of RPTK ligands, such as stem cell factor or a fragment thereof. Modulators of RPTK function can be used to treat diseases that are mediated by inappropriate RPTK activity.
摘要:
The present invention relates generally to the fields of immunology and medicine, and more specifically to the field of cellular signal transduction. The present invention relates, inter alia, to methods for diagnosis, treatment, and identification of therapeutics for particular inflammation-related diseases or disorders characterized by an interaction between a PYK2 polypeptide and a natural binding partner.
