Proprotein convertase subtilisin/kexin type 5 (PCSK5)

Serine endoprotease that processes various proproteins by cleavage at paired basic amino acids, recognizing the RXXX[KR]R consensus motif. Probably functions in the constitutive and regulated secretory pathways.

Plays an important role in pregnancy establishment by proteolytic activation of a number of important factors like BMP2, CALD1 and alpha-integrins. .
