40 results about "SH3 domain" patented technology

The SRC Homology 3 Domain (or SH3 domain) is a small protein domain of about 60 amino acid residues. Initially, SH3 was described as a conserved sequence in the viral adaptor protein v-Crk. This domain is also present in the molecules of phospholipase and several cytoplasmic tyrosine kinases such as Abl and Src. It has also been identified in several other protein families such as: PI3 Kinase, Ras GTPase-activating protein, CDC24 and cdc25. SH3 domains are found in proteins of signaling pathways regulating the cytoskeleton, the Ras protein, and the Src kinase and many others. The SH3 proteins interact with adaptor proteins and tyrosine kinases. Interacting with tyrosine kinases SH3 proteins usually bind far away from the active site. Approximately 300 SH3 domains are found in proteins encoded in the human genome. In addition to that, the SH3 domain was responsible for controlling protein-protein interactions in the signal transduction pathways and regulating the interactions of proteins involved in the cytoplasmic signaling.

Selective PARP-1 targeting for designing chemo/radio sensitizing agents

Poly(ADP-ribose) polymerase-1 (PARP-1) is a central signaling enzyme in a cell nucleus. PARP-1 is a target for the development of radio and chemo sensitizing agents in cancer treatment as well as providing protection from stroke. An SH3 domain and an SH3 ligand domain have now been discovered on the PARP-1 protein. These domains are involved in PARP-1 activation. This discovery makes possible the use of bioinformatics tools for the design of new drugs and strategies for drug target selection, specifically targeting the PARP-1 enzyme.

Targeted-assisted iterative screening (tais):a novel screening format for large molecular repertoires

This invention provides a new in vitro screening method for the detection of protein-protein and other interactions. The method has been developed and applied to a commercial cDNA library to search for novel protein-protein interactions. PDZ, WW and SH3 domains from PSD95, Nedd4, Src, Abl and Crk proteins were used as test targets. 12 novel putative and 2 previously reported interactions were identified for 6 protein interaction modules in test screens. The novel screening format, dubbed TAIS (target-assisted iterative screening), provides an alternative platform to existing technologies for a pair-wise characterization of protein-protein, and other, interactions.
