help with pCMV-myc vector - (Mar/20/2010 )
I have a question about clontec pCMV-myc vector. I want to clone a gene into EcoRI and NotI sites to form a fusion protein with myc. But I want to know if the sequence ahead of EcoRI site (begin at 868) will affect my protein structure. Thanks a lot!
It is impossible to say for certain what this linker region (or the myc tag in fact) will do to the native conformation of your protein. Anytime you tag a protein you run the risk of disrupting structure, function, localization, interactions, stability, ect... this is why you need to make sure you are doing all the appropriate controls. I do prefer small tags such as myc or HA to help minimize this risk. The extra sequence between the myc tag and your protein is going to be about 8 amino acids so it is unlikely to disrupt structure but you can always run the tagged protein through structure prediction software to see the likelihood for changes.
