Evolution of aq- and 3-Tubulin Genes as Inferred by the
Nucleotide Sequences of Sea Urchin cDNA Clones

Summary.Evolutionary studies on the tubulin multigene
families were initiated by nucleotide sequence analysis
of cDNA clones complementary to sea urchin (Lyte-
chinus pictus) testis a- and 3-tubulin mRNAS. Sequence
COmparisons of three partial 3-tubulin cDNA clones
(P31, pff2, p33) demonstrated the existence of tubulin
rnRNA heterogeneity, p32 and p33 contain identical
tubulin-coding regions and extremely similar 3' untrans-
lated sequences, including a polyadenylation signal
(AAUAAA). However, p132contains an additional region
of 3' untranslated sequence which includes a second
Polyadenylation signal. These two sequences may be
allelic, representing products of alternative transcription
