Former Common name
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strainICR
Strain developmentDeveloped by Dr. Hajime Fujisawa, Nagoya University in 1997. A neomycin selection cassette was inserted into a fragment of the sequence encoding the a1 domain of the protein. ICR background.
Strain descriptionICR.Cg-Nrp1<tm1Hfu>. Neuropilin-1 (Nrp1) is a type I membrane protein and has been shown to function as a receptor for semaphorin III/D. Nrp1 homozygous mutant mice were embryonic lethal, and show severe abnormalities in the trajectory of the cranial and spinal efferent fibers of the parasympathetic nerve system.
Colony maintenanceSibling Mating (Heterozygote x Wild-type, Heterozygote) or Cross to ICR (Heterozygote x Slc:ICR)Embryonic lethality (Homozygous). Homozygote mutant mice die up to E11.
