By making the hypothesis that the pattern of conserved sequence residues in the vicinity of the hydrolytic ATP-binding site of dynein would resemble that in myosins from a broad variety of sources, we designed degenerate oligonucleotide primers capable of amplifying this region of multiple dynein isoforms from sea urchin embryo poly(A)+ RNA. Quantification of the expression of two of these dynein isoforms has shown that the level of mRNA encoding for the beta-heavy chain, like that of tubulin, increases 2-3-fold after deciliation of the embryos, whereas the expression of the second dynein isoform, like that of actin, is essentially unaffected. This second isoform is believed to be the cytoplasmic dynein of sea urchin embryos.

D004398	Dyneins	A family of multi-subunit cytoskeletal motor proteins that use the energy of ATP hydrolysis, generated by a ring of AAA ATPASES in the dynein heavy chain, to power a variety of cellular functions. Dyneins fall into two major classes based upon structural and functional criteria.

D016415	Sequence Alignment	The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
