Also known as: LPLUNC1; C20orf114
Summary: The protein encoded by this gene may be involved in the innate immune response to bacterial exposure in the mouth, nasal cavities, and lungs. The encoded protein is secreted and is a member of the BPI/LBP/PLUNC protein superfamily. This gene is found with other members of the superfamily in a cluster on chromosome 20.

BPIFB1 loss alters airway mucus properties and diminishes mucociliary clearance.
Title: BPIFB1 loss alters airway mucus properties and diminishes mucociliary clearance.
BPIFB1 negatively regulates its interactor VTN, thereby inhibiting VTN-induced proliferation, antiapoptotic effects, G2/M phase arrest, DSB repair, and the activation of the ATM-Chk2 and ATR-Chk1 pathways after irradiation.
Title: BPIFB1 (LPLUNC1) inhibits radioresistance in nasopharyngeal carcinoma by inhibiting VTN expression.
A novel mechanism underlying the anticancer effect of LPLUNC1 and clarifying that PHB1 may represent a novel, promising candidate tumour suppressor gene in Nasopharyngeal carcinoma, with potential therapeutic target value.
Title: LPLUNC1 stabilises PHB1 by counteracting TRIM21-mediated ubiquitination to inhibit NF-κB activity in nasopharyngeal carcinoma.
Results showed that BPIFB1 expression markedly inhibited NPC cell migration, invasion, and lung-metastatic abilities. Additionally, identification of two BPIFB1-interacting proteins, VTN and VIM, showed that BPIFB1 reduced VTN expression and the formation of a VTN-integrin alphaV complex in NPC cells, leading to inhibition of the FAK/Src/ERK signalling pathway.
Title: BPIFB1 (LPLUNC1) inhibits migration and invasion of nasopharyngeal carcinoma by interacting with VTN and VIM.
BPIFA1 and BPIFB1 expressions are correlated with goblet cell metaplasia and inversely correlated with lung function parameters of airway obstruction (FEV1 and FEV1/FVC) in COPD patients.
Title: Association of innate defense proteins BPIFA1 and BPIFB1 with disease severity in COPD.
The G allele of rs1078761 may be detrimental to lung function in cystic fibrosis owing to decreased levels of BPIFA1 and BPIFB1.
Title: Polymorphisms associated with expression of BPIFA1/BPIFB1 and lung disease severity in cystic fibrosis.
higher sputum concentrations of BPIFB1 were associated with changes of lung function over time, especially in current smokers with chronic obstructive pulmonary disease. BPIFB1 may be involved in the pathogenesis of smoking-related lung diseases.
Title: Elevated sputum BPIFB1 levels in smokers with chronic obstructive pulmonary disease: a longitudinal study.
Autoimmunity targeting the lung-specific antigen BPIFB1 may contribute to the pathogenesis of interstitial lung disease.
Title: BPIFB1 is a lung-specific autoantigen associated with interstitial lung disease.
Results suggest that LPLUNC1 can inhibit inflammation and nasopharyngeal carcinoma (NPC) growth by downregulating the Stat3 pathway.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
