CC   -!- FUNCTION: [Small/secreted glycoprotein]: Seems to possess an anti-
CC       inflammatory activity as it can reverse the barrier-decreasing effects
CC       of TNF alpha. Might therefore contribute to the lack of inflammatory
CC       reaction seen during infection in spite the of extensive necrosis and
CC       massive virus production. Does not seem to be involved in activation of
CC       primary macrophages. Does not seem to interact specifically with
CC       neutrophils. {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: [Small/secreted glycoprotein]: Homodimer; disulfide-linked (By
CC       similarity). The homodimers are linked by two disulfide bonds in a
CC       parallel orientation (By similarity). {ECO:0000250|UniProtKB:P60170}.
CC   -!- SUBUNIT: [Delta-peptide]: Monomer.
CC   -!- SUBCELLULAR LOCATION: [Small/secreted glycoprotein]: Secreted
CC       {ECO:0000250|UniProtKB:P60170}.
CC   -!- SUBCELLULAR LOCATION: [Delta-peptide]: Secreted
CC       {ECO:0000250|UniProtKB:P60170}.
CC   -!- PTM: [Pre-small/secreted glycoprotein]: This precursor is processed
CC       into mature sGP and delta-peptide by host furin or furin-like
CC       proteases. The cleavage site corresponds to the furin optimal cleavage
CC       sequence [KR]-X-[KR]-R. {ECO:0000250|UniProtKB:P60170}.
CC   -!- PTM: [Small/secreted glycoprotein]: N-glycosylated.
CC       {ECO:0000250|UniProtKB:P60170}.
CC   -!- PTM: [Delta-peptide]: O-glycosylated. {ECO:0000250|UniProtKB:P60170}.
CC   -!- RNA EDITING: Modified_positions=295 {ECO:0000269|PubMed:8622982};
CC       Note=Partially edited. RNA editing at this position consists of an
CC       insertion of one or two adenine nucleotides. The sequence displayed
CC       here is the small secreted glycoprotein, derived from the unedited RNA.
CC       The sequence derived from the +1A edited gives rise to the full-length
CC       transmembrane glycoprotein GP (AC P87666), the +2A edited RNA gives
CC       rise to the super small secreted glycoprotein ssGP (AC P0C773).;
CC   -!- SIMILARITY: Belongs to the filoviruses glycoprotein family.
CC       {ECO:0000305}.
