description
Transgene Type:    Transgenic (Reporter)
Mutation:    Insertion
 
Mutation detailsThe transgene contains the lacZ gene under the control of a promoter consisting of three consensus lymphoid enhancer binding factor 1/transcription factor 3 (LEF/TCF)-binding motifs upstream of a minimal Fos promoter. This allele is responsive to canonical Wnt/beta-catenin signal transduction. (J:55937)

Notes
Homozygous transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities.

Transgenic mice express beta-galactosidase in the presence of the lymphoid enhancer binding factor 1/transcription factor 3 (LEF1/TCF3) mediated signaling pathway and activated Beta-catenin (CATNB).

Transgenic mice display Beta-galactosidase activity during early embryonic development in a subset of pluripotent embryonic basal cells of the epithelium and dermis of developing hair follicles. Beta-galactosidase activity is not detected in the next stage of hair follicle development, formation of hair germs. At E16.5, transgene activity reappears in hair follicles and is detectable until 18 days after birth.
