The invention relates to methods and compositions for identifying mutations associated with cancer, such as melanoma. More particularly, the invention relates to methods and compositions for assessing particular mutations as markers for cancer, such as melanoma. Such methods and compositions allow medical providers to diagnose cancer, such as melanoma, based upon the presence of one or more particular mutations in a subject, as compared with an otherwise healthy control. The methods and compositions are also useful in guiding the type of therapy to be applied, and monitoring the effects of the therapy applied.
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.

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 method for treatment of a disease or condition in an organism characterized by an abnormal level of interaction between a BLM domain and its natural binding partner is described. The disease or condition may also be characterized by an abnormality in a signal transduction pathway, wherein the pathway contains a protein with a BLM domain. The method includes disrupting or promoting that interaction (or signal) in vivo. The method also involves inhibiting the activity of the complex formed between the BLM domain-containing protein and its natural binding partner. A method for diagnosis of such a disease or condition by detecting the level of such interaction as an indication of that disease or condition is also described. Also, a method for screening for an agent useful for treatment of such a disease or condition by assaying potential agents for the ability to disrupt or promote that interaction is described. The invention also features a peptide comprising, consisting or consisting essentially of a BLM domain.
