| PubMed Abstract |
The unidirectional movements of the microtubule-associated motors, dyneins, and kinesins, provide an important mechanism for
the positioning of cellular organelles and molecules. An intriguing possibility is that this mechanism may underlie the directed
transport and asymmetric positioning of morphogens that influence the development of multicellular embryos. In this report,
we characterize the Drosophila gene, Dhc64C, that encodes a cytoplasmic dynein heavy chain polypeptide. The primary structure
of the Drosophila cytoplasmic dynein heavy chain polypeptide has been determined by the isolation and sequence analysis of
overlapping cDNA clones. Drosophila cytoplasmic dynein is highly similar in sequence and structure to cytoplasmic dynein isoforms
reported for other organisms. The Dhc64C dynein transcript is differentially expressed during development with the highest
levels being detected in the ovaries of adult females. Within the developing egg chambers of the ovary, the dynein gene is
predominantly transcribed in the nurse cell complex. In contrast, the encoded dynein motor protein displays a striking accumulation
in the single cell that will develop as the oocyte. The temporal and spatial pattern of dynein accumulation in the oocyte
is remarkably similar to that of several maternal effect gene products that are essential for oocyte differentiation and axis
specification. This distribution and its disruption by specific maternal effect mutations lends support to recent models suggesting
that microtubule motors participate in the transport of these morphogens from the nurse cell cytoplasm to the oocyte.
