CC -!- FUNCTION: sGP seems to possess an anti-inflammatory activity as it can
CC reverse the barrier-decreasing effects of TNF alpha. Might therefore
CC contribute to the lack of inflammatory reaction seen during infection
CC in spite the of extensive necrosis and massive virus production. Does
CC not seem to be involved in activation of primary macrophages. Does not
CC seem to interact specifically with neutrophils.
CC {ECO:0000250|UniProtKB:P60170}.
CC -!- FUNCTION: [Delta-peptide]: Viroporin that permeabilizes mammalian cell
CC plasma membranes. It acts by altering permeation of ionic compounds and
CC small molecules. This activity may lead to viral enterotoxic activity.
CC {ECO:0000250|UniProtKB:P60170}.
CC -!- SUBUNIT: sGP is a homodimer; disulfide-linked. The homodimers are
CC linked by two disulfide bonds in a parallel orientation. Delta-peptide
CC is a monomer (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Small/secreted glycoprotein]: Secreted.
CC -!- SUBCELLULAR LOCATION: [Delta-peptide]: Secreted {ECO:0000250}.
CC -!- PTM: Pre-sGP is N-glycosylated. This precursor is processed into mature
CC sGP and delta-peptide by host furin or furin-like proteases. The
CC cleavage site corresponds to the furin optimal cleavage sequence [KR]-
CC X-[KR]-R. Both cleavage fragments contain sialic acid, but only the
CC delta-peptide is O-glycosylated (By similarity). {ECO:0000250}.
CC -!- RNA EDITING: Modified_positions=295 {ECO:0000250}; Note=Partially
CC edited. RNA editing at this position consists of an insertion of one
CC adenine nucleotide. The sequence displayed here is the small secreted
CC glycoprotein, derived from the unedited RNA. The edited RNA gives rise
CC to the full-length transmembrane glycoprotein (AC P87671) (By
CC similarity). {ECO:0000250};
CC -!- SIMILARITY: Belongs to the filoviruses glycoprotein family.
CC {ECO:0000305}.
