Short Palate, Lung And Nasal Epithelium Carcinoma Associated Protein 3 (SPLUNC3)

SPLUNC3, Belongs to the BPI/LBP/Plunc superfamily. Plunc family. The PLUNC proteins are encoded by adjacent genes found within a 300 kb region of chromosome 20, suggesting that they may be under transcriptional control of shared genomic elements, and expression data shows that these proteins are found in overlapping regions of the pulmonary, nasopharyngeal and oral epithelium, sites where the previously described BPI family members are not expressed.Whereas the BPI family are predicted to share very closely similar three-dimensional structures, the PLUNC family is predicted to have much greater variability in the N-terminal domain, corresponding to the active domain of BPI, thus creating the notion of a BPI/PLUNC structural superfamily.
