General description

HIV-1 trans-activator of transcription (Tat) is an 11kDa protein, which regulates HIV-1 gene expression at the level of transcription and protein synthesis. It is located in the nucleus of infected cells. HIV-1 Tat functions as a transcriptional activator for the synthesis of full-length viral RNA. It induces RNA splicing. Tat is an RNA binding protein, which particularly recognizes trans activator response element (TAR) from the HIV-1 RNA molecule.

Biochem/physiol Actions

Synthetic peptide that includes the sequence responsible for the cellular uptake of the human immunodeficiency virus-1 Tat protein, consisting of the polycationic region 49–57. The peptide is part of the protein transduction domain (PTD) and was shown to enable the introduction of nucleic acids into cells.

Physical form

Lyophilized from 0.1% aqueous trifluoroacetate (TFA).

Other Notes

Lyophilized from 0.1% TFA in H2O

Nanoparticle carriers offer the possibility of enhanced delivery of therapeutic payloads in tumor tissues due to tumor-selective accumulation through the enhanced permeability and retention effect (EPR). Gold nanoparticles (AuNP), in particular, possess highly appealing features for development as nanomedicines, such
