mortality/aging
• no homozygotes are recovered at E8.5 to E16.5, however mutants are present at the 2-cell stage and E4.5, indicating lethality between E4.5 and E8.5
• 2-cell stage embryos grown in culture are able to compact at the 8- to 16-cell stages to form the morula but they cease to develop further into blastocysts

embryo
• morula embryos exhibit increased apoptosis, showing increased activated caspase-3, chromatin fragmentation, and decreased number of nuclei
