Grlf1 (glucocorticoid receptor DNA binding factor 1, also called p190 RhoGAP (GTPase activating protein)) is a potent Rho regulator that mediates integrin-dependent adhesion signaling in cultured cells. The gene is expressed at high levels throughout the developing nervous system.
This ENU-generated I602N mutation of Grlf1 creates a severe hypomorphic allele that displays phenotypes equivalent to those reported for the loss-of-function allele described in Brouns MR et al., Development 2000 Nov;127(22):4891-903. A small percentage of embryos are exencephalic and show neural tube closure defects that are likely linked to misregulation of cell adhesion processes.
Levels of the I602N transcript are unchanged in spinal cord and brain tissues, but protein levels are reduced. Mice homozygous for the mutation usually die within 2 days of birth.
This I602N (A>T) mutation (NCBI Reference Sequence: NM_172739.4) was generated by random ENU-induced mutagenesis of DBA/2J male mice. It was originally combined with a transgene and crossed with CB6F1 (BALB/c x C57BL/6) for approximately 6 generations by the donating laboratory. Upon arrival at The Jackson Laboratory, the two mutations were bred apart.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
