Visit our online Nomenclature tutorial. Species laboratory mouse Generation p+N2pN1p (09-NOV-05) Donating Investigator Sally Camper, University of Michigan Medical School Description
Mice hemizygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express the Cre recombinase under the control of the mouse glycoprotein hormone alpha-subunit promoter. Cre recombinase expression is detected in the anterior and intermediate lobes of the pituitary gland, as well as in cardiac and skeletal muscle. Low to no level of expression is detected in the posterior pituitary, lungs, kidneys, brain, adrenal glands and gonads. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in deletion of the targeted gene in the anterior pituitary. This strain represents an effective tool for generating tissue specific-targeted mutants that would be useful to study developmentally critical gene function in the anterior pituitary.Development
A transgenic construct containing a 4.6Kb sequence of mouse glycoprotein hormone alpha-subunit promoter upstream of the Cre recombinase gene, a nuclear localization signal, and beta-actin polyadenylation site sequence was injected into B6SJLF2 zygotes. Transgenic founder mice were obtained.

| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||

| General Note | Hemizygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. | ||
| Molecular Note | This transgene expresses Cre recombinase under the control of a mouse glycoprotein hormone alpha-subunit (Cga) gene. This promoter is active in the pituitary primordium beginning at embryonic day 9.5. Cre recombinase expression is detected in the anterior and intermediate lobes of the pituitary gland, in cardiac, and in skeletal muscle. Low to no level of expression is detected in the posterior pituitary, lungs, kidneys, brain, adrenal glands, and gonads. [MGI Ref ID J:66897] | ||
