Abstract

Corneodesmosin (CDSN) is an important component of the desmosome in the epidermal cornified stratum and inner root sheath of hair follicles. DNA from a sheep BAC clone previously identified by us to contain CDSN was PCR amplified using cattle-derived primers and the product sequenced. A region of 4579bp containing CDSN was shown to contain two exons separated by one intron and spanning 3683bp. The DNA encodes a predicted protein of 546 amino acids. Phylogenetic analysis shows that sheep CDSN falls within a clade containing cattle and other ruminant-like species. Comparison of sequences generated from 12 unrelated merino sheep and the International Sheep Genome Consortium (ISGC) data identified 58 single nucleotide polymorphisms (SNPs) within the 4579bp region of which 16 are contained within coding sequences (1 in 80bp). The SNPs identified in this study will add to the Major Histocompatibility Complex (MHC) SNP panel, which will allow extensive haplotyping of the sheep MHC in future studies.
