MUC1 has been reported to play an important role in cell‐cell interactions, cell‐matrix interactions, modulating tumor progression and metastasis,15, 16, 17, 18, 19 and also serves as an adhesion molecule for a number of pathogens, providing cells protection from bacteria.18, 20, 21 The cytoplasmic tail of MUC1 functions in cell signaling, with seven evolutionary conserved tyrosine phosphorylation sites and cytoplasmic domains that interact with other key signaling molecules, including ß‐catenin, p53, and NF‐κB.22, 23. The gene discussed is MUC1; the disease is neoplasm.
