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.
pmKate2-annexin is a mammalian expression vector encoding mKate2-annexin fusion protein (see reporter description). The vector can be used for fluorescent labeling of annexin A4 in living cells.
Translocation of mKate2 fusion with human annexin A4 from the cytoplasm to the plasma and nuclear membranes upon induction with ionomycin.
Human cervical adenocarcinoma cells (HeLa).
mKate2 codon usage is optimized for high expression in mammalian cells (humanized) [Haas et al., 1996]. Human annexin A4 is fused to the mKate2 C-terminus. To increase mRNA translation efficiency, Kozak consensus translation initiation site is generated upstream of the mKate2-annexin coding sequence [Kozak, 1987].
pmKate2-annexin vector can be used as a source of mKate2-annexin 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
pmKate2-annexin vector can be transfected into mammalian cells by any known transfection method. CMV promoter provides strong, constitutive expression of the mKate2-annexin fusion in eukaryotic cells. If required, stable transformants can be selected using G418 [Gorman, 1985].
