BPIFA1, Recombinant, Human, aa20-256, His-Tag (BPI fold-containing family A, member 1)

BPIFA1, also known as PLuNC, belongs to the short subfamily of PLuNC family proteins and have homology only to the N-terminal domains of BPI. It is a secreted protein that is expressed in the secretory ducts and submucosal glands of tracheobronchial tissues. BPIFA1 binds to lipopolysaccharide (LPS) in nasal lavage fluid (NLF) which points to its role in the inflammatory response of the upper airways after exposure to irritants. Decreased levels of BPIFA1 occur in the NLF of smokers and people who have been exposed to reactive epoxy chemicals, indicating that long-term exposure to airway irritants impairs the production of BPIFA1 in the upper respiratory tract. Source: Recombinant protein corresponding to aa20-256 of human BPIFA1, fused to His-tag at N-terminal expressed in E. coli.
