Background

PLUNC (Palate, lung, and nasal epithelium clone; also SPLUNC1) is a 25-30 kDa member of the PLUNC family, BPI/PLUNC/LBP superfamily of proteins. PLUNC is a secreted glycoprotein that is expressed by both adult and embryonic respiratory epithelium in the nose, trachea and bronchi/primary bronchioles. It serves as a natural antibacterial polypeptide in the respiratory system. Mature mouse PLUNC is 259 amino acids (aa) in length. It contains four, six-amino acid repeats (GxxLPL) over aa 23-52. There is reportedly one splice variant that shows a 28 aa substitution for the C-terminal 45 amino acids (aa 234-278). Over aa 59-278, mouse PLUNC shares 91% and 75% aa identity with rat and human PLUNC, respectively.
