Anti-SNCA Intrabody [Tat] (IAB-B031(T))

Recombinant anti-SNCA intrabody in fusion with HIV Tat works within cells to bind human monomeric wild-type SNCA, expressed in E. coli cells. The intrabody stabilizes detergent-soluble monomeric syn and inhibits the formation of detergent-insoluble high-molecular-weight syn species. In addition, the intrabody ameliorates the decreased cell adhesion that characterizes the syn-overexpressing cells. Anti-SNCA intrabodies may represent novel molecular therapeutics for synucleinopathies, with implications for other neurodegenerative disorders caused by misfolded accumulated proteins.

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.
