Anti-G3BP Intrabody [Tat] (IAB-B016(T))

Recombinant anti-G3BP intrabody in fusion with HIV Tat works within cells to bind intracellur antigen human G3BP, expressed in 293T cells. This inhibition is attributed to the blocking of the endogenous G3BP protein.      

human GTPase activating protein (SH3 domain) binding protein 1
Cell Penetrating Peptide
TAT was able to deliver different proteins, such as horseradish peroxidase and RNase A across cell membrane into the cytoplasm in different cell lines in vitro. The size range of proteins with effective delivery is from 30kDa to 120-150kDa. In one study, TAT-fused proteins are rapidly internalized by lipid raft−dependent macropinocytosis using a transducible TAT−Cre recombinase reporter assay on live cells. In another study, a TAT-fused protein was delivered into mitochondria of breast cancer cells and decreased the survival of breast cancer cells, which showed capability of TAT-fusion proteins to modulate mitochondrial function and cell survival. However, very few in vivo studies have succeeded. In one study, in vivo delivery of TAT- or penetratin-crosslinked Fab fragments yielded varied organ distributions and an overall increase in organ retention, which showed tissue localization.
