Summaries for BPIFA1 Gene

Entrez Gene Summary for BPIFA1 Gene

  • This gene is the human homolog of murine plunc, and like the mouse gene, is specifically expressed in the upper airways and nasopharyngeal regions. The encoded antimicrobial protein displays antibacterial activity against Gram-negative bacteria. It is thought to be involved in inflammatory responses to irritants in the upper airways and may also serve as a potential molecular marker for detection of micrometastasis in non-small-cell lung cancer. Multiple transcript variants resulting from alternative splicing in the 3' UTR have been detected, but the full-length nature of only three are known. [provided by RefSeq, Aug 2014]

GeneCards Summary for BPIFA1 Gene

BPIFA1 (BPI Fold Containing Family A Member 1) is a Protein Coding gene. Diseases associated with BPIFA1 include Hepatoid Adenocarcinoma and Nasopharyngeal Carcinoma. Among its related pathways are Innate Immune System and Defensins. Gene Ontology (GO) annotations related to this gene include lipid binding. An important paralog of this gene is BPIFA3.

UniProtKB/Swiss-Prot for BPIFA1 Gene

  • Plays a role in the innate immune responses of the upper airways. Reduces the surface tension in secretions from airway epithelia and inhibits the formation of biofilm by pathogenic Gram-negative bacteria, such as P.aeruginosa and K.pneumoniae. Binds bacterial lipopolysaccharide (LPS). Negatively regulates proteolytic cleavage of SCNN1G, an event that is required for activation of the epithelial sodium channel (ENaC), and thereby contributes to airway surface liquid homeostasis and proper clearance of mucus. Plays a role in the airway inflammatory response after exposure to irritants. May attract macrophages and neutrophils. May be associated with tumor progression.
