Specificity / Sensitivity

DDX6/RCK Antibody detects endogenous levels of total DDX6/RCK protein.

Species Reactivity:

Human, Mouse, Rat, Monkey

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human DDX6/RCK protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

DDX6, also known as RCK and p54, was identified as a proto-oncogene product and is a member of the ATP-dependent DEAD box helicase family (1,2). This protein interacts with translation initiation factor eIF4E in the cytoplasmic P-bodies (3) and represses mRNA translation (4). DDX6 is a component of the miRNA induced silencing complex (miRISC) and interacts with Argonaute 1 (Ago1) and Argonaute 2 (Ago2) proteins in vitro and in vivo (5), functioning in miRNA-mediated translational repression (5). Depletion of DDX6 leads to the disruption of cytoplasmic P-bodies indicating that it is required for P-body formation (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
