Recombinant Hepatitis C virus genotype 1a Genome polyprotein,partial

C-terminal 6xHis-Myc-tagged

18.7 kDa

Capsid proteins VP1, VP2, and VP3 form a closed capsid enclosing the viral positive strand RNA genome. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The capsid interacts with HAVCR1 to provide virion attachment to target cell.

Repeated freezing and thawing is not recommended. Store working aliquots at 4C for up to one week.

Core protein p21: Host endoplasmic reticulum membrane, Single-pass membrane protein, Host mitochondrion membrane, Single-pass type I membrane protein, Host lipid droplet, Note=The C-terminal transmembrane domain of core protein p21 contains an ER signal leading the nascent polyprotein to the ER membrane, Only a minor proportion of core protein is present in the nucleus and an unknown proportion is secreted, SUBCELLULAR LOCATION: Core protein p19: Virion, Host cytoplasm, Host nucleus, Secreted, 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, After cleavage, the membrane sequence is retained at the C-terminus of the protein, serving as ER membrane anchor, A reorientation of the second hydrophobic stretch occurs after cleavage producing a single reoriented transmembrane domain, These events explain the final topology of the protein, ER retention of E1 is leaky and, in overexpression conditions, only a small fraction reaches the plasma membrane, SUBCELLULAR LOCATION: Envelope glycoprotein E2: 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, After cleavage, the membrane sequence is retained at the C-terminus of the protein, serving as ER membrane anchor, A reorientation of the second hydrophobic stretch occurs after cleavage producing a single reoriented transmembrane domain, These events explain the final topology of the protein, ER retention of E2 is leaky and, in overexpression conditions, only a small fraction reaches the plasma membrane, SUBCELLULAR LOCATION: p7: Host endoplasmic reticulum membrane, Multi-pass membrane protein, Host cell membrane, Note=The C-terminus of p7 membrane domain acts as a signal sequence, After cleavage by host signal peptidase, the membrane sequence is retained at the C-terminus of the protein, serving as ER membrane anchor, Only a fraction localizes to the plasma membrane, SUBCELLULAR LOCATION: Protease NS2-3: Host endoplasmic reticulum membrane, Multi-pass membrane protein, SUBCELLULAR LOCATION: Serine protease NS3: Host endoplasmic reticulum membrane, Peripheral membrane protein, Note=NS3 is associated to the ER membrane through its binding to NS4A, SUBCELLULAR LOCATION: Non-structural protein 4A: Host endoplasmic reticulum membrane, Single-pass type I membrane protein, Note=Host membrane insertion occurs after processing by the NS3 protease, SUBCELLULAR LOCATION: Non-structural protein 4B: Host endoplasmic reticulum membrane, Multi-pass membrane protein, SUBCELLULAR LOCATION: Non-structural protein 5A: Host endoplasmic reticulum membrane, Peripheral membrane protein, Host cytoplasm, host perinuclear region, Host mitochondrion, Note=Host membrane insertion occurs after processing by the NS3 protease, SUBCELLULAR LOCATION: RNA-directed RNA polymerase: Host endoplasmic reticulum membrane, Single-pass type I membrane protein
