RESUMO
Expression of the Aspergillus nidulans brlA gene induces a developmental pathway leading to the production of asexual spores. We have introduced mutations into brlA that are expected to disrupt either or both Cys2-His2 Zn(II) coordination sites postulated to exist in the BrlA polypeptide. The resultant brlA alleles fail to induce either the asexual reproductive pathway or the expression of development-specific genes. These data support the hypothesis that brlA encodes a nucleic acid-binding protein whose activity requires each of two zinc fingers.

- The Aspergillus nidulans brlA regulatory locus consists of overlapping transcription units that are individually required for conidiophore development.
- Translational repression of brlA expression prevents premature development in Aspergillus.
- FluG and flbA function interdependently to initiate conidiophore development in Aspergillus nidulans through brlA beta activation.
- GRP2 proteins contain both CCHC zinc fingers and a cold shock domain.
- A palindromic regulatory site within vertebrate GATA-1 promoters requires both zinc fingers of the GATA-1 DNA-binding domain for high-affinity interaction.
