Detection and sequence analysis of the DNA repair gene RAD51 in the Korean spider Callobius koreanus (Amaurobiidae).

We identified a partial sequence (483 bp) of the RAD51 gene from the Korean spider Callobius koreanus. Sequence variation was found at one position during alignment with the human RAD51 gene sequence. This partial sequence included the region corresponding to exon 4 in the human RAD51 gene, which encodes 39 amino acids. These results show that the RAD51 gene is highly conserved between human and spiders.
