| Enzyme Function | FUNCTION: During the asexual blood stage, plays an essential role in the export of several proteins into the host erythrocytes by cleaving the pentameric localization motif RxLxE/Q/D (termed Plasmodium export element (PEXEL)) located downstream of the N-terminal secretory signal sequence (By similarity). Specifically, cleaves after the leucine residue in the RxLxE/Q/D (or RxLxxE) motif of exported proteins including RESA, EMP2, EMP3, KAHRP, RIF/Rifin and STEVOR (By similarity). Also, by regulating protein export, plays an essential role in gametocyte development and thus parasite transmission to the mosquito vector (By similarity). {ECO:0000250|UniProtKB:Q8I6Z5, ECO:0000250|UniProtKB:W7JPD9}. |

| Subcellular Location | SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000269|PubMed:16024107}; Single-pass type I membrane protein {ECO:0000250|UniProtKB:Q8I6Z5}. Note=During gametogenesis, localizes to the perinuclear ER in stage I-II gametocytes, and relocalizes towards the cell periphery as the ER redistributes in the cell in stage III-IV gametocytes (By similarity). Partially colocalizes with SPC25 in the endoplasmic reticulum (By similarity). {ECO:0000250|UniProtKB:W7JPD9}. |
| Modified Residue | |
| Post Translational Modification | PTM: It is not clear if the zymogen has a cleavable propeptide (PubMed:16024107). In vitro, appears to be cleaved between Asn-87 and Ala-88 (By similarity). Cleavage of the putative propeptide is dispensable for catalytic activity (By similarity). {ECO:0000250|UniProtKB:Q8I6Z5, ECO:0000269|PubMed:16024107}. |
