Protein attributes

Sequence length	707 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Stimulates RNA polymerase I transcription of the 47S precursor rRNA. Associates with ribosomal DNA (rDNA) loci where it is involved in POLR1A recruitment. Important element of nucleolar organization. Ref.7
Catalytic activity	ATP + H2O = ADP + phosphate.
Subunit structure	Interacts with UBTF. Ref.7
Subcellular location	Nucleus › nucleolus. Nucleus › nucleoplasm. Note: Predominantly in the nucleolus. During mitosis, localizes with the nucleolar organizing regions. Ref.5 Ref.7
Sequence similarities	Belongs to the DEAD box helicase family. DEAH subfamily. Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain.
Sequence caution	The sequence AAH30017.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
