| Sequence length | 1860 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Likely to represent a widespread endoprotease activity within the constitutive and regulated secretory pathway. Capable of cleavage at the RX(K/R)R consensus motif. Plays an essential role in pregnancy establishment by proteolytic activation of a number of important factors such as BMP2, CALD1 and alpha-integrins. Ref.9 Ref.10 Ref.11 |
| Catalytic activity | Release of mature proteins from their proproteins by cleavage of Arg-Xaa-Yaa-Arg-|-Zaa bonds, where Xaa can be any amino acid and Yaa is Arg or Lys. |
| Subcellular location | Isoform PC6A: Secreted. Note: Secreted through the regulated secretory pathway By similarity. Isoform PC6B: Endomembrane system; Single-pass type I membrane protein. Note: Type I membrane protein localized to a paranuclear post-Golgi network compartment in communication with early endosomes By similarity. |
| Tissue specificity | Expressed in T-lymphocytes. |
| Domain | The propeptide domain acts as an intramolecular chaperone assisting the folding of the zymogen within the endoplasmic reticulum. AC 1 and AC 2 (clusters of acidic amino acids) contain sorting information. AC 1 directs TGN localization and interacts with the TGN sorting protein PACS-1 By similarity. |
| Sequence similarities | Belongs to the peptidase S8 family. Contains 1 homo B/P domain. Contains 1 PLAC domain. |
