What this target is

Its function as UniProt states it, where in a cell the protein is found, and which cell types and tissues transcribe its gene.

ATP-dependent DNA helicase Q1

DNA helicase that plays a role in DNA damage repair and genome stability15886194,35025765,7527136,7961977,8056767. Exhibits a Mg(2+)- and ATP-dependent DNA-helicase activity that unwinds single- and double-stranded DNA in a 3'-5' direction19151156,35025765,7527136,8056767. Full-length protein unwinds forked DNA substrates, resolves Holliday junctions, and has DNA strand annealing activity19151156,25831490. Plays a role in restoring regressed replication forks35025765. Required to restart stalled replication forks induced by abortive topoisomerase 1 and 2 lesions35025765. Does not unwind G-quadruplex DNA18426915. May play a role in the repair of DNA that is damaged by ultraviolet light or other mutagens15886194,7961977

What it acts with

STRING’s highest-confidence human functional partners. The combined score mixes several kinds of evidence, so each channel is shown separately — a partner supported by experiment is a different claim from one supported only by text mining, and for a receptor this is where its coupling appears as evidence rather than as assertion.

Where it sits in the cell

  • Nucleoplasm

Human Protein Atlas, by antibody immunofluorescence in cell lines — a different assay from the expression figures below, which are RNA.

UniProt, curated Nucleus

Expression by cell type

Single cell type RNA, the 2 highest of those the Human Protein Atlas reports for this gene. Transcript, not protein, and a cell type rather than a tissue.

II · Anatomy

Where the gene is transcribed

The same two atlases the compound plates use, asked about this gene alone. Brain on the left, peripheral and autonomic tissues on the right.

030 nTPM

Square-root ramp · shared scale across both plates

Shading is transcript level — not affinity, and not affinity combined with expression. Outlined but unshaded organs hold none of RECQL transcript above the atlas’s detection threshold. Anatomy from EMBL-EBI Anatomogram (Apache License 2.0); regions identified by Uberon (uberon.org), CC BY 3.0.

Transcript is not protein. These are RNA levels for RECQL, shaded on √nTPM so that a three-order range stays legible — on a linear ramp every region but the strongest would read as blank, which looks like absence rather than less. A region carrying no shading is one the atlas reports no consensus value for, not one where the gene is silent. And a gene being transcribed somewhere is not evidence that any compound reaches it.
