Protein Gene Interaction Pubs
Envelope surface glycoprotein gp120 env SP-D inhibits HIV-1 gp120-CD4 interaction and acts like cell entry inhibitor of HIV-1 PubMed
env Surfactant protein D (SP-D) binds to HIV-1 gp120 and inhibits HIV infectivity; the binding of SP-D to gp120 depends on glycosylation of gp120 and multimerization of SP-D PubMed
env SP-D enhances the binding of HIV-1 gp120 to iMDDCs and induces viral uptake and transfer of HIV from iMDDCs to CD4+ T cells PubMed
env The binding of sDC-SIGN to HIV-1 gp120 is significantly inhibited by SP-D in a dose-dependent manner, indicating an overlap with the binding site for SP-D PubMed
Envelope surface glycoprotein gp160, precursor env HIV-1 gp160 binds to surfactant protein D in a dose- and calcium-dependent manner PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
