PF06550 Signal-peptide peptidase, presenilin aspartyl protease family

SPP is a family of signal-peptide aspartyl proteases. The family carries the characteristic catalytic aspartate GXGD motif, and members are integral membrane peptidases of the presenilin-type with nine transmembrane regions. UniProtKB:Q18K19 is part of the TCDB family 1.A.54.3.4, the presenilin er Ca(2+) leak channel (presenilin).
