-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Serpin B5; AltName: Full=Maspin; AltName: Full=Peptidase inhibitor 5; Short=PI-5;
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.
SUBUNIT: Interacts with IRF6.
SUBCELLULAR LOCATION: Secreted, extracellular space.
TISSUE SPECIFICITY: Normal mammary epithelial cells.
SIMILARITY: Belongs to the serpin family. Ov-serpin subfamily.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

ModBase Predicted Comparative 3D Structure on P36952
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
