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. {ECO:0000269|PubMed:11425234, ECO:0000269|PubMed:23132494, ECO:0000269|PubMed:23499554, ECO:0000269|PubMed:24043776, ECO:0000269|PubMed:24124190}. |LBP BPI CETP| |immune response in gut-associated lymphoid tissue| |immune response in nasopharyngeal-associated lymphoid tissue| |negative regulation of single-species biofilm formation in or on host organism| |regulation of liquid surface tension| |regulation of single-species biofilm formation in or on host organism| |negative regulation of single-species biofilm formation| |regulation of single-species biofilm formation| |immune response in mucosal-associated lymphoid tissue| |mucosal immune response| |organ or tissue specific immune response| |antibacterial humoral response| |regulation of sodium ion transmembrane transport| |antimicrobial humoral immune response mediated by antimicrobial peptide| |multicellular organismal water homeostasis| |water homeostasis| |regulation of sodium ion transport| |antimicrobial humoral response| |lipid binding| |defense response to virus| |negative regulation of multi-organism process| |regulation of symbiosis, encompassing mutualism through parasitism| |response to virus| |multicellular organismal homeostasis| |defense response to bacterium| |regulation of cation transmembrane transport| |humoral immune response| |regulation of metal ion transport| |regulation of ion transmembrane transport| |regulation of body fluid levels| |regulation of transmembrane transport| |response to bacterium| |regulation of ion transport| |molecular function| |innate immune response| |regulation of multi-organism process| |defense response to other organism| |immune effector process| |chemical homeostasis| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |extracellular space| |homeostatic process| |regulation of transport| |immune response| |extracellular region| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp538|ZLN024 50μM R08 exp538]]|-2.12| |[[:results:exp84|UM0125461 0.74μM R02 exp84]]|-1.8| |[[:results:exp539|42°C R08 exp539]]|2.09| ^Gene^Correlation^ |[[:human genes:p:polr2j3|POLR2J3]]|0.449| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 9240 * **Expression level (log2 read counts)**: -7.68 {{:chemogenomics:nalm6 dist.png?nolink |}}
