Figure 1.

Comparison of rat testis Sak57 (now designated K5) and human K5 amino acid sequences. The symbol + denotes conservative substitutions. Gaps were introduced to maximize homology. The diagram (not to scale) at the bottom indicates the head, rod, and tail domains of K5, as well as the subdomains and linkers of the rod domain. The corresponding amino acid sequences of the domains, subdomains, and linkers are indicated for both rat testis K5 (Sak57) and human K5 (hK5). The conserved sequences KAQYEDIANR in the 2A subdomain and LEGQECRLSGEGVG in the 2B-tail domain junction are indicated in yellow. GenBank accession number AY342389.
