WebbThe discovery of protein ubiquitination is a fine example of a “bottom to top” discovery and its role in ‘big’ biological processes, e.g. transcription, cell cycle, antigen processing, cellular defense, signalling etc. is now well established (Ciechanover and Iwai 2004; Varshavsky 2005). During the early days in the field of cytosolic ... WebbProtein synthesis begins with the interaction of the 30S subunit and mRNA through the Shine-Delgarno sequence. On formation of this complex, the initiator tRNA charged with formylmethionine binds to the initiator AUG codon, and the 50S subunit binds to the 30S subunit to form the complete 70S ribosome. What are the two main function of …

A guide to antigen processing and presentation - Nature

Antigen processing, or the cytosolic pathway, is an immunological process that prepares antigens for presentation to special cells of the immune system called T lymphocytes. It is considered to be a stage of antigen presentation pathways. This process involves two distinct pathways for processing of antigens from an organism's own (self) proteins or intracellular pathogens (e.g. viruses), or from phagocytosed pathogens (e.g. bacteria); subsequent presentation of these anti… howard county md procurementWebbCytosolic proteins are mainly involved in protein modification, mRNA degradation, metabolic processes, signal transduction, and cell death.
