Ankfyl is dispensable for neural stem/precursor cell development

There are few studies on the membrane protein Ankfyl. We have found Ankfyl is specifically expressed in neural stem/precursor cells during early development in mice （murine）. To further explore Ankfyl function in neural development, we developed a gene knockout mouse with a mixed Balb/C and C57/BL6...

Summary:There are few studies on the membrane protein Ankfyl. We have found Ankfyl is specifically expressed in neural stem/precursor cells during early development in mice （murine）. To further explore Ankfyl function in neural development, we developed a gene knockout mouse with a mixed Balb/C and C57/BL6 genetic background. Using immunofluorescence and in situ hybridization, neural defects were absent in mixed genetic Ankfyl null mice during development and in adults up to 2 months old. However, Ankfyl gene knockout mice with a pure genetic background were found to be lethal in the C57/BL6 inbred mice embryos, even after seven generations of backcrossing. Polymerase chain reaction confirmed homozygotes were unattainable as early as embryonic day 11.5. We conclude that Ankfyl protein is dispensable in neural stem/precursor ceils, but could be critical for early embryonic murine development, depending on the genetic background.
