Transgene Detail
Symbol: Tg(KRT5-rtTA)1Glk
Name: transgene insertion 1, Adam Glick
MGI ID: MGI:3575756
Synonyms: BK5/rTA, K5/rTA, K5-rtTA
Transgene: Tg(KRT5-rtTA)1Glk  Location: unknown  
Strain of Origin:  FVB/N
Transgene Type:    Transgenic (Transactivator)
Mutation:    Insertion
Mutation detailsThis transgene contains the reverse tetracycline-regulated transactivator gene rtTA under control of the bovine keratin 5 promoter. The rtTA coding sequence lies downstream of approximately 5.2 kilobases of DNA from the 5' flanking region of the keratin followed by a beta-globin intron and upstream of an SV40 polyadenylation signal.

This is one of 11 lines generated using this transgenic construct. Of the 11, five lines were characterized for their effect on expression of a tetO-lacZ reporter gene in doubly transgenic mice. Such mice, when treated with doxycycline, exhibit 3- or 30-fold elevated levels of beta-galactosidase (b-gal) activity in skin relative to levels in tetO-lacZ singly-transgenic mice. Immunohistochemical staining for b-gal detects expression in skin and hair follicles, specifically in the outer root sheath of hair follicles and, in one line, the basal layer of the epidermis. Lower-level induction occurs in tongue, forestomach and trachea. No significant b-gal is detected in tissues that do not express endogenous keratin 5 or in the absence of doxycycline. (J:65791)
