| description | Homozygous mutant embryos are inviable and die shortly after implantation. |
| molecularNote | An exon encoding 51 N-terminal amino acids comprising most of the RING finger domain was deleted and replaced with a PGK-neo cassette via homologous recombination. Western blot analysis of correctly targeted ES cells showed no detectable protein expression. Homozygous mutant embryos were observed at day E4.0 by PCR genotype analysis. |
