UniProt Protein Function: | maspin: Tumor suppressor. It blocks the growth, invasion, and metastatic properties of mammary tumors. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. Interacts with IRF6. Normal mammary epithelial cells. Belongs to the serpin family. Ov-serpin subfamily. 2 isoforms of the human protein are produced by alternative splicing. |
UniProt Protein Details: | Chromosomal Location of Human Ortholog: 18q21.33 Cellular Component: extracellular space; cytoplasm Molecular Function:serine-type endopeptidase inhibitor activity; protein binding Biological Process: extracellular matrix organization and biogenesis; morphogenesis of an epithelium; cell motility; regulation of epithelial cell proliferation |
