Strain Data Sheet



BRC No.RBRC01939
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129X1-Trpv4<tm1Msz>
Former Common nameTRPV4KO
H-2 Haplotype
ES Cell lineRW4 [129X1/SvJ]
Background strainC57BL/6JJcl
Appearanceblack [a/a b/b C/C]
Strain developmentDeveloped by Makoto Suzuki, Jichi Medical School in 2001. The construct was electoroporated into RW4 ES cells derived from 129X1/SvJ. The mutant mice were backcrossed to C57BL/6J.
Strain descriptionTRPV4 (Trpv4, transient receptor potential cation channel, subfamily V, member 4) knockout mice. Exon 4 encodes the ankyrin-repeat domain was replaced with a neomycin resistance gene. The ion channel TRPV4 is a member of the TRP family, acts as a Ca2+-permeable cation channel in response to mechanical stress. Homozygous mutant mice are viable and fertile, but show a reduced responsiveness to pressure sensation and abnormal osmotic regulation.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]
