The vector sequence has been compiled using the information from sequence databases, published literature, and other sources, together with partial sequences obtained by Evrogen. This vector has not been completely sequenced.
pTurboGFP-mito is a mammalian expression vector intended for green fluorescent labeling of mitochondria in living cells. The vector encodes green fluorescent protein TurboGFP (see reporter description) fused to mitochondrial targeting sequence (MTS) derived from the subunit VIII of human cytochrome C oxidase [Rizzuto et al., 1989; Rizzuto et al., 1995]. MTS is fused to the TurboGFP N-terminus.
Stably transfected HeLa cells expressing mitochondria-targeted TurboGFP.

TurboGFP codon usage is optimized for high expression in mammalian cells (humanized) [Haas et al., 1996].
pTurboGFP-mito vector can be used as a source of TurboGFP-MTS hybrid sequence. The vector backbone contains unique restriction sites that permit its excision and further insertion into expression vector of choice.
Note: The plasmid DNA was isolated from dam+-methylated
The vector backbone contains immediate early promoter of cytomegalovirus (PCMV IE) for protein expression, SV40 origin for replication in mammalian cells expressing SV40 T-antigen, pUC origin of replication for propagation in
SV40 early promoter (PSV40) provides neomycin resistance gene (Neor) expression to select stably transfected eukaryotic cells using G418. Bacterial promoter (P) provides kanamycin resistance gene expression (Kanr) in
Expression in mammalian cells
pTurboGFP-mito vector can be transfected into mammalian cells by any known transfection method. CMV promoter provides strong, constitutive expression of the TurboGFP-MTS fusion in eukaryotic cells. If required, stable transformants can be selected using G418 [Gorman, 1985].
