Your Heading Here (maybe something like 'Structure')

SARS-CoV-2 ORF3a (PDB entry 6xdc)

Drag the structure with the mouse to rotate

Function

Open Reading Frame 3a (ORF3a) Forms homotetrameric potassium sensitive ion channels (viroporin) and may modulate virus release. Up-regulates expression of fibrinogen subunits FGA, FGB and FGG in host lung epithelial cells. Induces apoptosis in cell culture. Downregulates the type 1 interferon receptor by inducing serine phosphorylation within the IFN alpha-receptor subunit 1 (IFNAR1) degradation motif and increasing IFNAR1 ubiquitination.[1][2]
