This knock-in line expresses a red fluorescent protein (mCherry) under control of the Nepn gene locus.  The line is unpublished but is shown to exhibit mCherry expression in kidney (see attached PowerPoint images).

Genetic Alteration

Mutation #1: Targeted Mutagenesis
Type of AlleleGlobal Null
Targeted GeneName: Nephrocan
Symbol: Nepn
NCBI: 66650
Allele Name: targeted mutation 1
Symbol: Nepntm1(Cherry)Mgn
Description of Targeting Vector

The targeting vector was made by BAC recombineering.  The vector contains a 5' homology arm of 8392 bp and a 3' arm of 3210 bp.  The 5' homology arm is followed by an mCherry-rabbit beta globin poly-A sequence and a FRT-flanked PGK-EM7-Neo cassette that is used for positive selection by Neomycin (targeting events).  The PGK-EM7-Neo cassette was excised by crossing to a FlpE-expressing mouse.
