Unrooted phylogenetic tree of the neck/tail domains of the
heavy chains of 144 myosins in classes I–XVII. The myosins are
identified by their classes as defined by previous phylogenetic trees
of their head domains and/or by the authors of the original papers
describing the myosin. Because of limited space, with a few exceptions,
the positions of individual myosins are not identified, and the
resolution is insufficient to show clearly all 47 myosin II branches.
As in Fig. 1, the distances between any two myosins is proportional to
the divergence between their amino acid sequences. The GenBank
accession numbers for each myosin and, in parentheses, the residue
numbers used to define the neck/tail domains, in addition to those
given in the previous figure legends are: class III—DmNINAC, P10676
(1007–1501); class IV—AcHMWM, IV, P47808 (740–1577); class X—Bt,
AAB39486 (728–2052); Mm, CAB56466 (728–2061); class XII—CeHum4,
CAA91469 (925–2810); class XIII—AclMyo1, AAB53061 ();
AclMyo2, AAB53062 (800–1145); class XV—Mm, AAC40124 (703–1783);
class XVI—RnMyr8, AAF20150 (1133–1322); class XVII—EnCsmA, BAA21714
(756–1852); PgCsm, BAA74449 (767–1869). Abbreviations are as in
previous figures and Acl, Acetabularia cliftonii (alga);
Pg, Pyricularia grisea (blast fungus).
