This deletion was created by cre mediated recombination of loxP sites within Nmur2 (created by random insertion vector of loxP-Puro cassette) and Sparc (created by eliminating exon 6 and replacing it with a Neo-LoxP as well as inserting stop codons in all three reading-frames). The deletion spans a 0.5 Mb Mb interval between Nmur2 and Sparc and includes Glra1, G3bp1 and Atox1. (J:155870)
