RL   Submitted (MAR-2010) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Protease with a carboxypeptidase B-like function involved in
CC       the C-terminal processing of the lysine and arginine residues from
CC       protein precursors. Promotes cell fusion and is involved in the
CC       programmed cell death (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Preferential release of a C-terminal arginine or lysine
CC         residue.; EC=3.4.16.6;
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus, trans-Golgi network membrane
CC       {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase S10 family. {ECO:0000305}.
