SignalSilence® APC6 siRNA I #7279
Western blot analysis of extracts from 293T cells, transfected with 100 nM SignalSilence® Control siRNA (Unconjugated) #6568 (-), SignalSilence® APC6 siRNA I (+) or SignalSilence® APC6 siRNA II #7164 (+), using APC6 (D8D8) Rabbit mAb #9499 (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). The APC6 (D8D8) Rabbit mAb confirms silencing of APC6 expression, while the GAPDH (D16H11) XP® Rabbit mAb is used as a loading control.Learn more about how we get our images

CST recommends transfection with 100 nM SignalSilence® APC6 siRNA I 48 to 72 hours prior to cell lysis. For transfection procedure, follow protocol provided by the transfection reagent manufacturer. Please feel free to contact CST with any questions on use.
Each vial contains the equivalent of 100 transfections, which corresponds to a final siRNA concentration of 100 nM per transfection in a 24-well plate with a total volume of 300 μl per well.Storage: SignalSilence® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.
SignalSilence® APC6 siRNA I from Cell Signaling Technology (CST) allows the researcher to specifically inhibit APC6 expression using RNA interference, a method whereby gene expression can be selectively silenced through the delivery of double stranded RNA molecules into the cell. All SignalSilence® siRNA products from CST are rigorously tested in-house and have been shown to reduce target protein expression by western analysis.
Oligonucleotide synthesis is monitored base by base through trityl analysis to ensure appropriate coupling efficiency. The oligo is subsequently purified by affinity-solid phase extraction. The annealed RNA duplex is further analyzed by mass spectrometry to verify the exact composition of the duplex. Each lot is compared to the previous lot by mass spectrometry to ensure maximum lot-to-lot consistency.
Cell proliferation in all eukaryotic cells depends strictly upon the E3 ubiquitin ligase activity of the anaphase promoting complex/cyclosome (APC/C), whose main function is to trigger the transition of the cell cycle from metaphase to anaphase. APC/C performs its various functions by promoting the assembly of polyubiquitin chains on substrate proteins, which targets these proteins for degradation by the 26S proteasome (1,2). In humans, twelve different APC/C subunits have been identified. Like all E3 enzymes, APC/C utilizes ubiquitin residues that have been activated by E1 enzymes and then transferred to E2 enzymes. Indeed, APC/C has been shown to interact with UBE2S and UBE2C E2 enzymes, in part, via the RING-finger domain-containing subunit, APC11 (3-5). APC/C activity is also strictly dependent upon its association with multiple cofactors. For example, the related proteins, cell division control protein 20 homolog (CDC20) and Cdh1/FZR1, participate in the recognition of APC/C substrates by interacting with specific recognition elements in these substrates (6), called D-boxes (7) and KEN-boxes (8).
APC6/CDC16 is a component of the tetratricopeptide repeat (TPR) sub-complex of the APC/C, which also consists of APC8/CDC23 and APC3/CDC27. It is thought that this sub-complex plays an important role in coordinating the juxtaposition of the catalytic and substrate recognition modules relative to co-activator, regulatory proteins, and substrates (9). There is also evidence suggesting that phosphorylation of APC6 and the other TPR subunits during mitosis plays a functional role in regulating the association between TPR subunits and substrate recognition subunits such as Cdc20 (10).
