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.

1 GO annotations of cellular component

Name Definition
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

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.
