Abstract

In this paper, we report the full characterization, at DNA and RNA level, of the defective goat CSN1S1 F and N alleles and an extensive comparison with the A allele counterpart. By utilizing genomic DNA as template, we amplified the whole CSN1S1 gene plus 1972/3 nucleotides of the 5′ region plus 610 nucleotides of the 3′ region of the goat CSN1S1 N and CSN1S1 F alleles. Comparison of sequences of the N, F and A CSN1S1 alleles showed a total of 118 polymorphic sites. In particular, both the N and the F alleles are characterized by a deletion of the cytosine at the 23rd nucleotide of the 9th exon. The resulting one-nucleotide frameshift determines a premature stop codon (TGA, nucleotides 17–19 of the 12th exon). On the basis of the information so far available, it seems reasonable to hypothesize that the CSN1S1 N allele might be originated by interallelic recombination events. Comparison of transcripts produced by the N and F alleles shows a remarkable variability in alternative splicing events which concern, even though with different percentage ratios, mainly the lack of the 9th exon, the deletion of the last 5 nucleotides of the 9th exon and the contemporary deletion of exons 10 and 11.
