Hi all,
I noticed Invitrogen to offer a vector containing the VP22 protein as
label for secretion and subsequent nuclear localization of VP22
fusion proteins.
For those not familiar with the system: It's said to work like this:
1) transfect your VP22-fusion vector into easily maintainable cells
e.g. 293 fibroblasts
2) lyse 293 cells, add the lysate to those cells you want the protein
to be incorporated, e.g. myotubes)
However, I would like my protein to be directed into the cytoplasm of
my target cells, not into the nucleus.
Is anyone aware of the structure/domain - function relationship of
VP22 or knows another method of targetting proteins into the cytosol
of non transfectable cells?
Thanks for all input!
