26670139 cytoprotective effect of lacritin is mediated through Cyclooxygenase-2 (COX-2).
24942736 the C terminus of lacritin is multifunctional by dose and proteolytic processing and appears to play a key role in the innate protection of the eye
23769845 Genomic analysis expands the number of predicted lacritin orthologs, and suggests that secondary structure may be largely conserved. All currently known tear proteins predicted to be extracellular by GEO are assembled, and functions summarized.
23748026 Lacritin is a component of vampire bat saliva, as detected by mass spectrometry.
23640897 Lacritin rapidly and transiently accelerates autophagy to rid stressed cells of aggregated proteins. Lacritin also restores oxidative phosphorylation. LC3-II, in the absence of autophagic inhibitor, decreases as a consequence of rapidly increased flux.
23504321 Targeting of heparanase-modified syndecan-1 by prosecretory mitogen lacritin requires conserved core GAGAL plus heparan and chondroitin sulfate as a novel hybrid binding site that enhances selectivity.
23482462 Lacritin stimulates tear protein secretion from lacrimal acinar cells stressed with inflammatory cytokines, however under the same conditions carbachol is completely ineffective. Inflammatory cytokines are elevated in dry eye, the most common eye disease. The implication is that topical lacritin might be an effective therapeutic for dry eye.
23425695 Tissue transglutaminase promotes crosslinking of lacritin between K82 or K85 and Q106 - the latter residing in the SDC1 binding domain of lacritin necessary for cell targeting, thus inactivating lacritin. Tissue transglutaminase is thought to be upregulated in dry eye, the most common eye disease.
23422824 Lacritin protein yields were improved primarily by hydrophobic or salt bridge mutagenesis and less so by elimination of rare codons.
23308132 Lacritin is 10-fold less in tears from individuals suffering from fungal keratitis, and is barely detectable in the initial stage of infection by Fusarium solani. Fungal keratitis accounts for half of all corneal ulcers in Africa and India.
