Peptide Name   ApoEdpL-W

Sequence  WRKWRKRWWWRKWRKRWW

Sequence Length  18

UniProt ID  No entry found

Source  Synthetic construct



Activity Information


Target Organism  HSV,HIV,VSV

Assay  plaque reduction assay

Activity 

  • [Ref.17681018]HSV-1:inhibition of virus infection in NP-2/CD4/CCR5 cells(IC50=3.1 µM);
  • HIV-1:inhibition of virus replication(>80% inhibition at 10 µM).

Hemolytic Activity 

  • [Ref.17681018]15% hemolysis against human red blood cells at 35 μM.

Cytotoxicity 

  • [Ref.17681018]No significant cytotoxicity against Vero cells up to 40 μM.

Binding Target  Not found

Mechanism  The anti-HSV1 activity of apoEdp involves inhibition of virus particle attachment to cells, with this likely being related to the derivation of this peptide from the apoE HSPG/LDLR binding region.
