Expression of Pitx2 in mouse tooth

paired-like homeodomain transcription factor 2; Otlx2; ried bicoid related homeobox transcription factor 1 (RIEG1); pituitary homeobox 2 (Ptx2); solurshin; All1 responsive gene (Arp1); Munc30

Species: mouse
Location in mouse genome: chromosome 3, 132812431 - 132832072 (UCSC, assembly October 2003)
Method: in situ hybridization (radioactive), probe: 535nt


Initiation stage
Expression: oral epithelium, dental epithelium
No expression: dental mesenchyme

In Pitx2 null mutant mice tooth development is arrested at bud stage.
Mutations in PITX2 gene cause Rieger syndrome.
