COVID-19 research v0.349 VPS11 Rebecca Foulger commented on gene: VPS11: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): The VPS11 gene encodes a protein which is part of the homotypic fusion and vacuole protein-sorting (HOPS) complex that mediates fusion of endosome and lysosomes; VPS11 is involved in late-stage endosome to lysosome maturation. In HAP1 cells mutagenized with a retroviral gene-trap vector, mutations in VSP11 were enriched in Ebola virus-resistant cells. In addition, VPS11-deficient cells showed resistance to Ebola and Marburg virus compared to controls. Escape of the Ebola virus to the cytoplasm was blocked in VPS11-deficient cells (Carette et al. 2011). In HeLa cells RNAi downregulation of VPS11 showed decreased relative percentage infection with mouse hepatitis coronavirus (MHV) and feline infectious peritonitis virus, with a larger effect for MHV (Burkard et al. 2014). Similarly, in HEK293 cells, luciferase activity of Ebola virus and SARS-CoV-S were reduced in siRNA downregulated VPS11 cells (Zhou et al. 2016).

PMID 21866103; Carette et al. (2011) - Used retroviral gene-trap vector to mutagenize HAP1 cells. Identified genes enriched for mutations in vesicular stomatitis virus bearing the EboV glycoprotein (rVSV-GP-EboV)-resistant cells. Enriched for mutations in VPS11 as well as other subunits of the HOPS complex (six subunits including VPS11), which mediates fusion of endosome and lysosomes; VPS11 is involved in late-stage endosome to lysosome maturation. In addition, VPS11-deficient cells (using gene-trap insertions) showed resistance to infection with Marburg virus or Ebola virus (Figures 1C and Figure S4C) compared to controls. Ebola virus escape to the cytoplasm is blocked in VPS11-deficient cells compared to WT (Figure 3D)

PMID 25375324; Burkard et al. (2014) - Evaluated entry of mouse hepatitis coronavirus (MHV) in HeLa cells with GFP-expressing MHV RNAi mediated downregulation of VPS11 (using three different siRNAs) showed the percentage of relative infection was reduced compared to negative siRNA controls (Figure 1C). Luciferase expressing feline infectious peritonitis virus (FIPV) was also evaluated in HeLa cells and RNAi mediated downregulation of VPS11 showed reduced relative infection for two of three siRNAs compared to negative siRNA controls (Figure 10)

PMID 26953343; Zhou et al. (2016) - Study to evaluate effects of antibiotics on proteins involved in virus entry. SiRNA-mediated knockdown of VSP11 expression showed decreased relative luciferase activity in HEK293 cells infected with Ebola virus or SARS-CoV-S, but not with vesicular stomatitis virus. In addition, treatment with the glycopeptide antibiotic teicoplanin did not show an effect on the HOPS complex
COVID-19 research v0.347 VPS33A Alison Coffey commented on gene: VPS33A: Evidence Summary from Illumina curation team: VPS33A is a member of the Sec1/Munc18-related (SM) protein family and a core component of the class C core vacuole/endosome tethering (CORVET) and the homotypic fusion and protein sorting (HOPS) complexes (Vasilev et al. 2020). Both complexes are heterohexamers and share four subunits. VPS33A, VPS11, VPS16 and VPS18, involved in endolysosomal pathway. Deficiency of VPS33A was shown to affect susceptibility to certain viruses in cell culture, including Ebola and Marburg viruses (Carette et al. 2011), however no human studies confirming this association were identified.
