Overview

Basic information about this protein and its source genome.

Accession: PA3782
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA3782
Status: annotated
Amino acids: 317
Structure source: AlphaFold

GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons. GO:0043565 Binding to DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding. GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.

Target profile

Computed evidence for target prioritization.

Human off-target: No hit
Gut microbiome off-target: hit

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

52 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
