Also known as BTF3aBTF3b
Summary
BTF3 (basic transcription factor 3, HGNC:1125) is a protein-coding gene on chromosome 5q13.2, encoding Transcription factor BTF3 (P20290). When associated with NACA, prevents inappropriate targeting of non-secretory polypeptides to the endoplasmic reticulum (ER). It is a selective cancer dependency (DepMap: 69.9% of cell lines).
This gene encodes the basic transcription factor 3. This protein forms a stable complex with RNA polymerase IIB and is required for transcriptional initiation. Alternative splicing results in multiple transcript variants encoding different isoforms. This gene has multiple pseudogenes.

Literature-anchored findings (GeneRIF, showing 19)
- BTF3 is overexpressed in pancreatic ductal adenocarcinoma , where it acts as a transcriptional regulator rather than a direct modulator of apoptosis. (PMID:17312387)
- BTF3 interacts with ERalpha that has been activated either by 17beta-estradiol (ligand-dependent activation) or by epidermal growth factor (ligand-independent activation). (PMID:18025262)
- In addition to RNA polymerase II (otherwise RNA pol II, RNA polymerase B), four general transcription factors are required for initiation of transcription: BTF1 (also referred to as TFIID) which has recently been cloned from yeast, BTF2, BTF3 and STF. (PMID:2320128)
- may have a functional role in protecting against caries (PMID:23363935)
- BTF3 overexpression may be an early event in colorectal cancer development and could be useful biomarker for the early stage of colorectal cancers (CRC); BTF3 has positive correlations with NF-kappaB, RAD50, MRE11, NBS1 and AEG-1 and might influence complex signal pathways in CRC (PMID:23532689)
- BTF3 expression is associated with enhanced cell proliferation, reduced cell cycle regulation and apoptosis and its silencing decreased colony forming and proliferation of gastric cancer cells. (PMID:23901224)
- BTF3, HINT1, NDRG1 and ODC1 protein over-expression in human prostate cancer tissue (PMID:24386364)
- Findings provide a novel understanding of the mechanism of gastric cancer and highlight the important role of BTF3/FOXM1 in tumor growth and BTF3/JAK2/STAT3 in EMT and metastasis (PMID:28276310)
- TCGA analysis reveals high expression levels of BTF3 in luminal/ER + breast cancer and cell line models harboring ERalpha overexpression. Concordantly, BTF3 expression is highly and strongly associated with ESR1 expression in multiple breast cancer cohorts. (PMID:30315845)
- Study showed that BTF3 is overexpressed in prostate cancer (PCa) tissues and correlates with stem-like traits. Cancer stem-like characteristics in PCa including self-renewal and metastatic potential were impaired by BTF3 loss. BTF3 could stabilize BMI1, a crucial regulator of prostate stem cell self-renewal. More importantly, data revealed that BTF3 is highly predictive of poor prognosis. (PMID:31138311)

Transcription factor BTF3 — P20290 (reviewed: P20290)
Alternative names: Nascent polypeptide-associated complex subunit beta, RNA polymerase B transcription factor 3

UniProt curated annotations — full annotation on UniProt →
Function. When associated with NACA, prevents inappropriate targeting of non-secretory polypeptides to the endoplasmic reticulum (ER). Binds to nascent polypeptide chains as they emerge from the ribosome and blocks their interaction with the signal recognition particle (SRP), which normally targets nascent secretory peptides to the ER. BTF3 is also a general transcription factor that can form a stable complex with RNA polymerase II. Required for the initiation of transcription.
Subunit / interactions. Part of the nascent polypeptide-associated complex (NAC), which is a heterodimer of NACA and BTF3 (via NAC-A/B domains). NAC associates with ribosomes through the BTF3/NACB subunit. Both subunits can contact nascent polypeptide chains.
Subcellular location. Cytoplasm. Nucleus.
Similarity. Belongs to the NAC-beta family.
