Plasmid name: pLGM-CSF12 (LMBP 2746)
|Price category:||Cat. 1 (cf. price list)|
|Status:||GeneCorner non-core plasmid|
|Cloned DNA:||Mouse granulocyte macrophage colony stimulating factor genomic DNA (mGM-CSF)|
|Promoter:||Mouse granulocyte macrophage colony stimulating factor promoter (GM-CSF)
Escherichia coli lac operon promoter
|Selection marker:||Ampicillin (amp)|
|Replicon:||Escherichia coli plasmid pMB1 origin|
|Host range:||Escherichia coli|
|Parental clone:||pUC13; λGM-CSF12|
|Further information:||The plasmid was constructed as follows: the mouse GM-CSF gene was isolated from a sperm DNA library in the λ phage vector Charon 4A and the 12 kb EcoRI insert of one clone, λGM-CSF12, was subcloned into the unique EcoRI site of pUC13. The orientation of this insert was experimentally verified with a SalI-SphI digestion.
This plasmid was used to analyze the organization of the mouse GM-CSF gene, in order to compare it with the structure of human GM-CSF genes as well as with the structure of other inducible T-cell lymphokine genes such as IL2, IL3 and IFNγ.
Strong conservation in the 5' flanking regions of mouse and human GM-CSF genes suggests that these sequences may play a role in regulating expression of the genes during T-cell activation.
The mouse GM-CSF promoter is excisable as an EcoRI-ScaI fragment.
Experimentally verified restriction sites indicated on the circular map: BamHI, EcoRI, EcoRV, HindIII, NdeI, SacI, SalI, ScaI, SphI and XbaI.
Other experimentally verified restriction sites:
Asp700 (XmnI): cutting frequency = 6 or 7; one site is located in the mouse GM-CSF promoter region; a second site is located in the third exon of the gene; a third site is located in the pUC13 part of the vector; the positions of the other sites are unknown.
BglII: cutting frequency = 2; one site is located in the second intron of the mouse GM-CSF gene; the second site must be located either in the 5' or 3' flanking region of the gene.
HindII: cutting frequency = 7; one site is located in the multicloning site of the pUC13 part of the vector; the positions of the other sites are unknown.
KpnI: cutting frequency is probably 2; one site is located in the second intron of the mouse GM-CSF gene.
StuI: cutting frequency = 5; two sites are located in the mouse GM-CSF promoter region; a third site is located in the 3' flanking region of the gene; the positions of the other two sites are unknown.
When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide.
The nucleotide sequence of the 5' and 3' flanking regions of the mouse GM-CSF gene is not known.
