Description

These synaptogamin 3 and 6 knock-out and synaptotagmin 5 and 10 knock-in quadruple targeted mutation mice have no overt phenotype, but may be useful in further characterizing these genes and examining potential roles in vesicular trafficking and signal transduction. No overt phenotype has been reported.

Development

The Syt5 knock-in was created by inserting a tetracysteine motif tag dimer (Flag-CCPGCC-Flag-Flag-CCPGCC-Flag) in exon 3 of the gene. Exon 3 was additionally flanked by loxP sites and an Frt-flanked neomycin resistance cassette was placed 3' of the exon. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-{\i Kitl{\up +}}-derived R1 embryonic stem (ES) cells. The donating laboratory may have removed the neomycin cassette.

The Syt 10 knock-in was created by inserting a tetracysteine tag (Flag-C(4)-Flag) in exon 2 of the gene. Exon 2 was additionally flanked by loxP sites. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-{\i Kitl{\up +}}-derived R1 embryonic stem (ES) cells. An Flp-neomycin-Flp cassette placed in intron 1 has been removed.

The Syt3 knock-out was created through the insertion of a neomycin resistance cassette in exon 1 (amino acid 220 of NCBI protein NP_061995; bp 3738 of NCBI GeneID:20981).

The Syt6 knock-out was created through the insertion of a neomycin resistance cassette in amino acid 964/ bp 10938.

The four independently-created mutations were intercrossed to create the quadruple-mutant mice. It is probable that (129X1/SvJ x 129S1/Sv)F1-Kitl⁺ -derived R1 embryonic stem (ES) cells were used to create these mutations with chimera's crossed to C57BL/6.
