Dynein neighbor-joining tree. Inferred amino acid sequences were
aligned with clustalw (33), and the MEGA2
package (34) was used to construct this neighbor-joining tree. The
clustering of kl-3 with
Chlamydomonas γ-dynein and the autosomal paralog
CG9492 is clear, as is the clustering of
kl-5 with Chlamydomonas
β-dynein. The autosomal paralog Dhc 93AB. kl-2
clusters with the Chlamydomonas inner arm dynein 1β.
Because of its short length, CG9068 (the autosomal paralog of
kl-2) could not be included in the phylogeny, but both
proteins are closely related, having an amino acid identity of 53%.
