DICER1 Antibody – Rabbit Polyclonal

This gene encodes a protein possessing an RNA helicase motif containing a DEXH box in its amino terminus and an RNA motif in the carboxy terminus. The encoded protein functions as a ribonuclease and is required by the RNA interference and small temporal RNA (stRNA) pathways to produce the active small RNA component that represses gene expression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2010]

DICER1: a cytoplasmic type-III RNase that plays a central role in RNA interference (RNAi) pathways to produce the active small RNAs that represses gene expression. Possesses a DEAD box RNA helicase motif in its amino terminus and a dsRNA-binding motif in the carboxy terminus. Dicer, along with Ago2 andTRBP, are the main components of the RNA-induced silencing complex (RISC). Fragile X syndrome repeats form RNA hairpins that are cut by Dicer but do not activate the interferon-inducible protein kinase, PKR. Four alternatively spliced isoforms have been described.
