Gene Information

human ... MUC5AC(4586)

General description

The MUC5AC (mucin 5AC, oligomeric mucus/gel-forming) gene is mapped to human chromosome 11p15.5. Muc5ac is a gel-forming mucin of 40MDa, secreted by the goblet cells of the conjunctiva. Muc5ac is localized to the intermediate aqueous layer of tear film and predominant mucin in the respiratory tract. Muc5ac protein consists of cysteine-rich domains that flanks the central glycosylated tandem repeat domain.

Immunogen

MUC5AC (XP_495860, 351 a.a. ~ 450 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Application

Muc5ac (mucin 5AC, oligomeric mucus/gel-forming) provides hydration and lubrication effect for epithelial cells that make up cornea and conjunctiva. Parasympathetic and sympathetic nervous system (particularly, parasympathetic neurotransmitters acetylcholine and vasoactive intestinal peptide) controls the Muc5ac secretion. A number pathogens and cytokines can also stimulate Muc5ac secretion in the airway. MUC5AC gene expression is associated with a some pathological conditions such as allergen-induced airway hyperresponsiveness,airway mucus plugging, and mucous metaplasia.
