What is the function of this protein?
Cysteine protease required for the proteolytic auto-cleavage between the non-structural proteins NS2 and NS3 (By similarity).  The N-terminus of NS3 is required for the function of NS2 protease (active region NS2-3) (By similarity).  Promotes the initiation of viral particle assembly by mediating the interaction between structural and non-structural proteins (By similarity).
What are the official names of this protein?
Genome polyprotein.
What is the protein family that this protein belongs to?
Belongs to the hepacivirus polyprotein family.
What are the subcellular locations of this protein?
[Core protein precursor]: Host endoplasmic reticulum membrane; Single-pass membrane protein. Host mitochondrion membrane; Single-pass type I membrane protein. Note=The C-terminal transmembrane domain of the core protein precursor contains an ER signal leading the nascent polyprotein to the ER membrane. SUBCELLULAR LOCATION: [Mature core protein]: Virion. Host cytoplasm. Host nucleus. Host lipid droplet. Note=Only a minor proportion of core protein is present in the nucleus (By similarity). Probably present on the surface of lipid droplets (By similarity). SUBCELLULAR LOCATION: [Envelope glycoprotein E1]: Virion membrane; Single-pass type I membrane protein. Host endoplasmic reticulum membrane; Single-pass type I membrane protein. Note=The C-terminal transmembrane domain acts as a signal sequence and forms a hairpin structure before cleavage by host signal peptidase (By similarity). After cleavage, the membrane sequence is retained at the C-terminus of the protein, serving as ER membrane anchor (By similarity). A reorientation of the second hydrophobic stretch occurs after cleavage producing a single reoriented transmembrane domain (By similarity). These events explain the final topology of the protein (By similarity). SUBCELLULAR LOCATION: [Envelope glycoprotein E2]: Virion membrane; Single-pass type I membrane protein. Host endoplasmic reticulum membrane; Single-pass type I membrane protein. Host lipid droplet. Note=The C-terminal transmembrane domain acts as a signal sequence and forms a hairpin structure before cleavage by host signal peptidase (By similarity). After cleavage, the membrane sequence is retained at the C-terminus of the protein, serving as ER membrane anchor (By similarity). A reorientation of the second hydrophobic stretch occurs after cleavage producing a single reoriented transmembrane domain (By similarity). These events explain the final topology of the protein (By similarity). SUBCELLULAR LOCATION: [Viroporin p7]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. Host mitochondrion. Host cell membrane. Note=The C-terminus of p7 membrane domain acts as a signal sequence (By similarity). After cleavage by host signal peptidase, the membrane sequence is retained at the C- terminus of the protein, serving as ER membrane anchor (By similarity). ER retention of p7 is leaky and a small fraction reaches the plasma membrane (By similarity). SUBCELLULAR LOCATION: [Protease NS2]: Host endoplasmic reticulum membrane; Multi-pass membrane protein. Host lipid droplet. Note=Probably present on the surface of lipid droplets.
