Superficially wild-type except for a slightly shorter body length in adults. Crispr/Cas9 was used to create a 13 bp deletion in exon7 of ccar-1a; breakpoints: CTGATTCGGGAG/sda11/ATCGGAAGTTTC. sda11 is an isoform-specific deletion allele. It only affects the function of CCAR-1A and CCAR-1D, but not CCAR-1B and C. In addition, because CCAR-1D is not expressed in embryos,this allele can be used to specifically inactivate CCAR-1A (the full-length isoform that is the most similar to human CCAR1) during embryogenesis.
