Emx1^tm1Jlr

Insertion of a PGK-neomycin resistance cassette replaced exon 1 and part of intron 1 of the Emx1 gene. Northern analysis of E14.5 embryos did not detect Emx1 transcript in homozygous mutant mice. The authors predict that the mutant allele would produce a truncated protein that lacks the N-terminus. (J:35060)
