General annotation (Comments)
sGP seems to possess an anti-inflammatory activity as it can reverse the barrier-decreasing effects of TNF alpha. Might therefore contribute to the lack of inflammatory reaction seen during infection in spite the of extensive necrosis and massive virus production. Does not seem to be involved in activation of primary macrophages. Does not seem to interact specifically with neutrophils By similarity.
Delta-peptide does not seem to be involved in activation of primary macrophages By similarity.
sGP is a homodimer; disulfide-linked. The homodimers are linked by two disulfide bonds in a parallel orientation. Delta-peptide is a monomer By similarity.
Pre-sGP is N-glycosylated. This precursor is processed into mature sGP and delta-peptide by host furin or furin-like proteases. The cleavage site corresponds to the furin optimal cleavage sequence [KR]-X-[KR]-R. Both cleavage fragments contain sialic acid, but only the delta-peptide is O-glycosylated By similarity.
Belongs to the filoviruses glycoprotein family.
