Mutation origin

• Strain of Origin: C57BL/6J

Mutation description

• Allele Type: Spontaneous (Hypomorph)
• Mutation: Single point mutation
• Mutation details: Low levels of melatonin production in C57BL/6J mice have been correlated with a point mutation in the gene encoding arylalkylamine N-acetyltransferase. A G to A conversion within a cryptic splice site results in the preferential incorporation of a pseudo-exon, containing an in-frame stop codon as the second codon, into the transcript. In vitro analysis demonstrates that the resulting truncated protein, which lacks several conserved C-terminal motifs, has less than 1% enzyme activity when compared to control C3H/HeJ mice.
