Abstract Adaptor proteins are critical for signal transduction events involving cytokine signaling, host-response, and autoimmune diseases. Our laboratory is interested in understanding the immune regulatory role of 14-3-3zeta (z), an adaptor protein, transductions We examined 14-3-3z interleukin-17 (IL-17A) signaling inflammatory arthritis using genetically modified cells rats. The IL-17A requ...

Protein phosphorylation on tyrosine (Tyr) residues has evolved as an important mechanism to coordinate cell communication in multicellular organisms. The importance of this process has been revealed by the discovery of the prominent oncogenic properties of tyrosine kinases (TK) upon deregulation of their physiological activities, often due to protein overexpression and/or somatic mutation. Rece...

Scaffold proteins play a crucial role in facilitating signal transduction in eukaryotes by bringing together multiple signaling components. In this study, we performed a systematic analysis of scaffold proteins in signal transduction by integrating protein-protein interaction and kinase-substrate relationship networks. We predicted 212 scaffold proteins that are involved in 605 distinct signali...

An astounding number of important regulatory and structural proteins are subject to modification by the attachment of ubiquitin or ubiquitin-like proteins. This modification acts as a targeting signal, delivering the modified protein to different locations in the cell and modifying its activity, macromolecular interactions, or half-life. Deubiquitination, or the removal of this modification, is...

recombinant protein production in e. coli has several advantages over other expression systems. misfolding, inclusion body formation, and lack of eukaryotic post translational modification are the most disadvantages of this system. exporting of correctly folded proteins to the outside of reductive cytoplasmic environment through twin-arginine system could help to pass these limiting steps. two ...
