Protein (function)
Early transcribed membrane protein (ETRAMP) family member. Plasmodium conserved family with greater than ten members in P. falciparum. ETRAMPs are abundantly expressed early in the intraerythrocytic cycle and are small (frequently less than 200 aa) integral membrane proteins that are localized within the parasitophorous vacuolar membrane (PVM). All members have signal peptides plus a transmembrane domain. The ETRAMP/SEP proteins of P. yoelii and P. berghei (8-11 genes) show homology to members of the ETRAMP family of proteins of P. falciparum (14 genes) but the orthologous relationship of the different members is not completely resolved.
Phenotype
Phenotype analyses indicate that PY04799 has no essential role during the complete life cycle. Blood stage, mosquito stage and liver stage development of mutant parasites was similar to that of wild type parasites.
Additional information
The ETRAMP/SEP proteins of P. yoelii and P. berghei (8-11 genes) show homology to members of the ETRAMP family of proteins of P. falciparum (14 genes) but the orthologous relationship of the different members is not completely resolved.

In P. berghei mutants have been generated that lack expression of the 'ortholog' of PY04799, PBANKA_052480 (PbSEP1)(see RMgm-16 and RMgm-18). Phenotype analyses indicate that PbSEP1 has no essential role during the complete P. berghei life cycle.
