Segmental distribution of bithorax complex proteins during Drosophila development
Nature
|February 14, 1985
Summary
The bithorax complex in Drosophila melanogaster contains Ubx and bxd transcription units. Researchers determined protein distributions and localization, supporting a model where Ubx encodes proteins regulated by bxd.
Area of Science:
- Developmental Biology
- Genetics
- Molecular Biology
Background:
- The bithorax complex (BXC) in Drosophila melanogaster controls regional identity in the embryo.
- The Ubx and bxd transcription units within the BXC are known to play crucial roles in development.
Purpose of the Study:
- To investigate the functional relationship between the Ubx and bxd transcription units.
- To determine the segmental distribution and nuclear localization of Ubx-encoded proteins.
Main Methods:
- Immunofluorescence staining using antibodies against Ubx fusion proteins.
- Analysis of protein distribution in wild-type and mutant Drosophila melanogaster.
Main Results:
- The Ubx unit encodes proteins with specific segmental distributions and nuclear localization patterns.
- Observed distributions in wild-type and mutant strains align with a proposed regulatory model.
Conclusions:
- The Ubx and bxd transcription units function as a single domain.
- Protein-coding functions are attributed to the Ubx unit, with regulation provided by the bxd unit.
