    Experimental Models: Cell Lines
    Mammalian cell culture, transfection, and drug treatment: HeLa and HEK 293T cells were obtained from ATCC and maintained in a humidified atmosphere at 5% CO2 in Dulbecco’s Modified Eagle’s (DMEM) complete medium (Corning) supplemented with 10% fetal bovine serum (FBS; Seradigm) in 37°C.
    suggested: None
    Western Blotting and immunoprecipitation: For immunoprecipitation, either HA-tagged NRP1 (or mutants) and Flag-tagged SARS-CoV-2-S (or S1493-685) mutant or HA-tagged NRP1 (or mutants) and Flag-Plexin-A1 were expressed where indicated in 293T cells for 30 hours.
    suggested: None
    RNA-seq analysis: For RNA-seq analysis, Total RNA was extracted from HEK293T cell line 30 hours post transfection (HA-NRP1 and SARS-CoV-2-S1493-685 and or HA-NRP1-4Cys-4Ala and SARS-CoV-2-S1493-685) using TRIzol reagent (Invitrogen) according to the manufacturer’s instructions.
    suggested: None
    Recombinant DNA
    Plasmids and recombinant proteins: HA-NRP1 and different mutants of HA-NRP1, Flag-Plexin-A1, Flag-SARS-CoV-2-S-original (NC_045512.2), Flag-SARS-CoV-2-B.1.1.7-S, Flag-SARS-CoV-B.1.351-S were all obtained from GenScript (Cloned into pcDNA 3.1 vector).
    pcDNA 3.1
    suggested: RRID:Addgene_20407)
    For cycloheximide stability assay, 293T cells were transfected with the constructs encoding HA-NRP1 or HA-NRP1 mutants.
    suggested: None
    Software and Algorithms
    The PAN domain coordinates from Uniprot were used to extract the PAN domain sequences from the full-length proteins which were then aligned with MAFFT linsi(54).
    suggested: (MAFFT, RRID:SCR_011811)
    The alignment was visualized with Geneious.
    suggested: (Geneious, RRID:SCR_010519)
    The raw RNA-seq reads have been deposited at NCBI under BioProject ID PRJNA767890.
    suggested: (NCBI BioProject, RRID:SCR_004801)
    Reads were mapped with bowtie2 v2.2.5. (55).
    suggested: (Bowtie 2, RRID:SCR_016368)
    Differential expression analysis was performed with DESeq2, genes with an adjusted p-value less than 0.05 were considered differentially expressed (56).
    suggested: (DESeq, RRID:SCR_000154)
    Statistical analysis: Statistical analyses were performed on individual experiments, as indicated, with GraphPad Prism 8 Software using an unpaired t-Test, equal variance for comparison between two groups and one-way ANOVA for comparisons between more than two groups.
    GraphPad Prism
    suggested: (GraphPad Prism, RRID:SCR_002798)

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
