Human(7311) Summary: Ubiquitin is a highly conserved nuclear and cytoplasmic protein that has a major role in targeting cellular proteins for degradation by the 26S proteosome. It is also involved in the maintenance of chromatin structure, the regulation of gene expression, and the stress response. Ubiquitin is synthesized as a precursor protein consisting of either polyubiquitin chains or a single ubiquitin moiety fused to an unrelated protein. This gene encodes a fusion protein consisting of ubiquitin at the N terminus and ribosomal protein L40 at the C terminus, a C-terminal extension protein (CEP). Multiple processed pseudogenes derived from this gene are present in the genome. [provided by RefSeq, Jul 2008]

MISSION® siRNAs have been designed using a world-class siRNA design algorithm licensed from Rosetta Inpharmatics, a leader in advanced siRNA research. The Rosetta-powered siRNA design algorithm has been optimized with over 3 years of continuous development for enhanced performance in RNAi applications. New and critical siRNA design rules incorporated into the latest algorithm lead to increased target specificity and knockdown for low abundance messages.
Validated MISSION® siRNAs have been functionally validated in Hela cells by Sigma scientists to Knockdown gene expression by 75% or greater. With Validated MISSION® siRNAs, we have done the upfront validation work, so that you do not have to.
