Serpin B5 (UniProt P36952; also known as Maspin, Peptidase inhibitor 5, PI-5) is encoded by the SERPINB5 (also known as PI5) gene (Gene ID 5268) in human. Serpin B5/Maspin is an evolutionarily conserved serine protease inhibitor that induces apoptosis and inhibits the motility of breast cancer cells. DNA hypermethylation and histone deacetylation lead to silencing of the SERPINB5 gene in human breast cancer.
Specificity
Does not detect spliced isoform 2 (UniProt P36952-2).

Maspin (SERPINB5) is a potential tumor suppressor gene with pleiotropic biological activities, including regulation of cell proliferation, death, adhesion, migration and gene expression. Several studies indicate that nuclear localization is essential for maspin tumor suppression activity. We have previously shown
