| Primary Identifier | MGI:3707556 | Allele Type | Transgenic |
| Attribute String | Dominant negative, Humanized sequence, Inserted expressed sequence | Gene | Tg(ACTB-MAP2K1*K97M)1Stl |
| Strain of Origin | C57BL/6 | Is Recombinase | false |
| Is Wild Type | false |
| molecularNote | The transgene encodes a dominant-negative mutant (K97M) form of human MEK1 (or MAP2K1). Expression under the control of the chicken Actin beta promoter occurs only following Cre-mediated removal of the upstream Lox-STOP-Lox cassette. In the absence of Cre recombinase, the transgene is not detectably expressed in the brains of these floxed mice. If bred to a Cre-expressing strain, the floxed stop region is excised in the resulting offspring, and mutant MEK1 expression is observed in the cre-expressing tissue(s). |
