Descriptions

DEAD-box proteins utilize ATP to bind and remodel RNA and RNA-protein complexes. The Ded1/DDX3 subfamily of DEAD-box proteins is of particular interest as their function during protein translation, are essential for viability, and are frequently altered in human malignancies. <br>There is a unique interdomain interaction between the two ATPase domains (DEAD box helicase domain and helicase domain) in which the C-terminal helicase domain clashes with the RNA-binding surface. Destabilizing this interaction accelerates RNA duplex unwinding, suggesting that it is present in solution and inhibitory for catalysis. The N-terminal extension to the DEAD box helicase interacts with DEAD box helicase domain and C-terminal helicase domain, and stabilizes the autoinhibited state of DDX3X.

3 GO annotations of cellular component

Name Definition
cytosol The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
nucleolus A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.
peroxisome A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism.

4 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
ATP hydrolysis activity Catalysis of the reaction
mRNA binding Binding to messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.
RNA helicase activity Unwinding of an RNA helix, driven by ATP hydrolysis.
