Human(2065) Summary: This gene encodes a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity. Heterodimerization leads to the activation of pathways which lead to cell proliferation or differentiation. Amplification of this gene and/or overexpression of its protein have been reported in numerous cancers, including prostate, bladder, and breast tumors. Alternate transcriptional splice variants encoding different isoforms have been characterized. One isoform lacks the intermembrane region and is secreted outside the cell. This form acts to modulate the activity of the membrane-bound form. Additional splice variants have also been reported, but they have not been thoroughly characterized. [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.
