BRC No.RBRC02322
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129P2-Cmah<tm1Ykoz>
Former Common nameCmah null mouse, KZO
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strainC57BL/6JJcl
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Hiromu Takematsu and Yasunori Kozutumi, Graduate School of Biostudies, Kyoto University in 2000. E14 ES cells were used. The mutant mice were backcrossed to C57BL/6J.
Strain descriptionCmah gene knockout mice. A neo cassette was inerted into the second coding exon. This mouse is deficient for the biosynthesis of N-glycolylneuramic acid, one of the major species of sialic acid. Due to the deficiency, sialic acid species of this mouse is almost 100% N-acetylneuraminic acid, which is the precursor of N-glycolylneuraminic acid in the biosynthetic pathway. Since CMAH is one of rare gene inactivated in human but retained in the other homonids such as chimpanzee. Thus, this mouse could by utilized to mimic human in terms of the sialic acid species expression.
Colony maintenanceHeterozygote x Wild-type [C57BL/6JJcl]
