MUC1 (Mucin 1)

MUC1 (Mucin 1) is a type of protein found on the surface of many cells, especially in the lining of organs like the lungs, stomach, and breasts. It plays a key role in protecting and lubricating these tissues by trapping dirt, bacteria, and other harmful substances. Additionally, MUC1 helps cells communicate and respond to their environment. In some cancers, MUC1 is produced in abnormal amounts or forms, which can assist cancer cells in growing and spreading. Scientists study MUC1 to better understand its role in health, disease, and potential targets for treatments.
