Strain of Origin:  FVB/N
Transgene Type:    Transgenic (Inserted expressed sequence)
Mutation:    Insertion
Tg(H2-D-Il15)3304Clgr expresses 1 gene
Mutation detailsThe coding region of the transgene comprises a cDNA encoding the mature mouse IL15 protein (nt 610-951) joined to the signal peptide-encoding sequence of the mouse IL2 gene (nt 49-108) and followed by a FLAG epitope tag coding sequence. Upstream of, and in frame with, the coding sequence is the nearly ubiquitously expressed promoter of the H2-Dd major histocompatibility class I gene, and downstream of and out of frame with it is the 3' end of the human growth hormone gene. RT-PCR and immunoblot analysis for the FLAG epitope detected high levels of mRNA and protein, respectively, in numerous tissues. Whereas IL15 is undetectable in sera of wild-type mice, measurable levels are present in ~75% of transgenic sera. (J:67478)

Posttranscriptional checkpoints that maintain low endogenous wild-type IL15 intra- and extracellular protein levels - a series of 5' AUGs, the poorly translated and secreted IL15 signal peptide sequence and a C-terminal retention signal - have been eliminated from the transgene and replaced with sequences that maximize IL15 expression. (J:67478)

Although three transgenic lines were created in the FVB/N background, the phenotype is reported only for line 3304; the others are 3284 and 3285. It is stated that the phenotypes of all three are similar, but differ in severity depending on the level of transgene mRNA expression. (J:67478)
