MUC-4  is involved in the progression of cancer and endometriosis.
Mucin 4 (MUC 4) is a mucin protein that in humans is encoded by the MUC4 gene. It is also found to play roles in other diseases such as endometriosis and inflammatory bowel disease. MUC-4 has been found to play various roles in the progression of cancer, particularly due to its signaling and anti-adhesive properties which contribute to tumor development and metastasis.
