PURB
protein-coding gene in the species Homo sapiens
Transcriptional activator protein Pur-beta is a protein that in humans is encoded by the PURB gene.
Function
This gene product is a sequence-specific, single-stranded DNA-binding protein. It binds preferentially to the single strand of the purine-rich element termed PUR, which is present at origins of replication and in gene flanking regions in a variety of eukaryotes from yeasts through humans. Thus, it is implicated in the control of both DNA replication and transcription.
Clinical significance
Deletion of this gene has been associated with myelodysplastic syndrome and acute myelogenous leukemia.
“PURB” enters the record as protein-coding gene in the species Homo sapiens. Crown Archives preserves that source wording while asking what PURB, protein-coding and gene can confirm, complicate or overturn.
Why this record matters
“PURB” is worth following because a concise public description often conceals a longer documentary argument. Here, PURB, protein-coding and gene provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q18030964. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “PURB”, its source revision and the description used here.
- Expand the search: follow PURB primary sources, PURB archive and PURB research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
- Which source most directly establishes the central claim about “PURB”?
- Which observation, specimen, dataset or publication supports the account?
- Has classification or technical consensus changed since the cited source?
