| molecularNote | Exons 5-8 were replaced with a neo cassette via homologous recombination resulting in deletion of 45% of the protein product including a kinase domain and PQ-rich domain. Western blot of testicular samples from homozygous mutant animals verified the absence of protein and enzyme assays were negative for kinase activity. |
