CC -!- FUNCTION: Probable catalytic subunit of the gamma-secretase complex, an
CC endoprotease complex that catalyzes the intramembrane cleavage of
CC integral membrane proteins such as Notch receptors (lin-12 or glp-1).
CC Probably works redundantly of lin-12, which provides more presenilin
CC function. {ECO:0000269|PubMed:10051671}.
CC -!- SUBUNIT: Homodimer. Component of the gamma-secretase complex, a complex
CC probably composed of the presenilin homodimer (sel-12, hop-1 or spe-4),
CC nicastrin (aph-2), aph-1 and pen-2 (Probable). {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}. Golgi apparatus membrane
CC {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Weakly expressed.
CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically.
CC Predominantly expressed in the adult. Weakly expressed in the embryo,
CC L2 and L3 stages, and almost absent in L1 stage larvae.
CC {ECO:0000269|PubMed:12668626}.
CC -!- INDUCTION: Down-regulated by spr-1, spr-3, spr-4 and spr-5.
CC -!- DOMAIN: The PAL motif is required for normal active site conformation.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase A22A family. {ECO:0000305}.
