General annotation (Comments)

Function

Can unwind double-stranded RNA (helicase) and can fold or introduce a secondary structure to a single-stranded RNA (foldase). Functions as cofactor for JUN-activated transcription. Involved in rRNA processing. Ref.9 Ref.10

Catalytic activity

ATP + H2O = ADP + phosphate.

Subunit structure

Component of the B-WICH complex, at least composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6, MYBBP1A and DDX21. Interacts with C1QBP. Ref.12 Ref.21

Subcellular location

Nucleusnucleolus Ref.1.

Domain

The two enzymatic activities reside in two separate domains, the helicase in the N-terminus and the foldase in the C-terminus.

The 3 X 5 AA repeats seem to be critical for the RNA folding activity By similarity.

Miscellaneous

Autoantibodies against DDX21 are found in patients with watermelon stomach disease, which is characterized by prominent stripes of ectatic vascular tissue in the stomach similar to stripes on a watermelon.

Sequence similarities

Belongs to the DEAD box helicase family. DDX21/DDX50 subfamily.

Contains 1 helicase ATP-binding domain.

Contains 1 helicase C-terminal domain.

Sequence caution

The sequence AAB02546.1 differs from that shown. Reason: Erroneous initiation.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9NR30-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q9NR30-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-68: Missing.
