Enhancement of antiviral activity of human alpha-defensin 5 against herpes simplex virus 2 by arginine mutagenesis at adaptive evolution sites.

abstract：:In addition to PTAP L domains, primate lentiviruses carry Alix-binding motifs that include the recently described type 3 SREKPYKEVTEDLLHLNSLF sequence. We examined the requirements for the type 3 sequence motif in simian immunodeficiency virus SIV(smE543) and identified the (499)LNSLF(503) sequence as a key functional...
