Flavivirus non-structural protein NS4A (IPR000404)

Short name: Flavi_NS4A

Overlapping homologous superfamilies


Domain relationships



Flaviviruses encode a single polyprotein. This is cleaved into three structural and seven non-structural proteins. The NS4A protein is small and poorly conserved among the Flaviviruses. NS4A contains multiple hydrophobic potential membrane spanning regions [PMID: 2174669]. NS4A has only been found in cells infected by Kunjin virus [PMID: 2541547].
