Graphical View of Domain Structure for InterPro Entry



  • Q8TCT6
  • The PAL motif is required for normal active site conformation (By similarity). The catalytic domains embedded in the membrane are in the opposite orientation to that of the presenilin protein family; therefore, it is predicted to cleave type II-oriented substrate peptides like the prototypic protease SPP.
  • The first transmembrane domain may act as a type I signal anchor
  • Belongs to the peptidase A22B family.
