  • Function:
    UniProtKB/Swiss-Prot Summary: SPB5_HUMAN, P36952 Function: 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 Gene Ontology (GO): 2 molecular function terms: About this table GO ID Qualified GO term Evidence PubMed IDs GO:0004867 serine-type endopeptidase inhibitor activity IBA -- GO:0005515 protein binding IPI 16049006 [IMAGE] Find genes that share ontologies with SERPINB5 About GenesLikeMe Phenotypes: 2 GenomeRNAi human phenotypes for SERPINB5: Decreased number of cells in m Synthetic lethal with Ras
