Dicer, also known as Dicer1, endoribonuclease Dicer, Helicase with RNase motif is a member of the RNase III family. It contains a N-terminal DEXH-box RNA helicase/ ATPase domain, followed by a domain of unknown function (DUF283), a Piwi/Argonaut/Zwill (PAZ ) domain, which anchors the 3′-end of RNA substrates.
Dicer1 is encoded by the gene mapped to human chromosome 14q32.13.
Specificity
Anti-Dicer recognizes human Dicer.
Application
Anti-Dicer antibody produced in rabbit has been used in:
immunoblotting
immunoprecipitation
immunofluorescent staining
Biochem/physiol Actions
Dicer catalyzes the first step in the RNA interference (RNAi) pathway and initiates formation of the RNA-induced silencing complex (RISC). Dicer processes the dsRNA into small fragments called short interfering RNA (siRNA) or microRNA (miRNA) of typically 21-25 nucleotides long with a two-base overhang on the 3′. It helps to load these fragments into the RNA-induced silencing complex (RISC), which guides the sequence-specific silencing of mRNAs that contain complementary sequences by either enzymatically cleaving the mRNA or repressing its translation.
Mutation in the Dicer gene causes malignancies.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Storage and Stability
Store at –20 °C. For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

MicroRNAs are small noncoding 18- to 24-nt RNAs that are predicted to regulate expression of as many as 30% of protein-encoding genes. In prostate adenocarcinoma, 39 microRNAs are up-regulated, and six microRNAs are down-regulated. Production and function of microRNA requires
