Serine (or cysteine) peptidase inhibitor, clade B, member 5
Serpin peptidase inhibitor
Serpin peptidase inhibitor, clade B (ovalbumin), member 5
功能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.
组织特异性Normal mammary epithelial cells.
序列相似性Belongs to the serpin family. Ov-serpin subfamily.
