TMPRSS4 (Transmembrane Protease, Serine 4): TMPRSS4 is a member of the transmembrane serine protease family, known for its role in processing various proteins involved in physiological and pathological processes. This enzyme is localized on the cell surface, where it participates in the activation of proteins by cleaving peptide bonds. TMPRSS4 has been implicated in several critical biological pathways, including cell migration, invasion, and the regulation of epithelial-mesenchymal transition (EMT), which is pivotal in development, wound healing, and cancer metastasis. Its overexpression is associated with the progression of various cancers, making TMPRSS4 a potential biomarker for cancer diagnosis and prognosis, as...
