msgO

msgO is a protein found in humans and other mammals. It belongs to a family of proteins known as mucins, which are characterized by their high content of O-glycosylated serine and threonine residues. These complex sugar chains are attached to the protein backbone and play a significant role in the protein's function and physical properties.

The primary function of msgO is believed to be related to lubrication and protection. Like other mucins, it is a major component of mucus, a viscous fluid that lines various surfaces of the body, including the respiratory tract, digestive system, and eyes. In these locations, mucus acts as a physical barrier, trapping foreign particles and pathogens, and preventing them from reaching underlying tissues. The lubricating properties of mucus also help to facilitate movement and reduce friction.

msgO is encoded by the MUC7 gene. Its expression pattern suggests it is particularly important in the salivary glands and may contribute to the protective and lubricating qualities of saliva. Research into msgO continues to explore its precise roles in health and disease, with potential implications for understanding conditions involving abnormal mucus production or function.
