Abstract:
The CP2 transcription factors are highly conserved in metazoans, where they are divided into two groups: grainyhead and late SV40 factor (LSF). We traced their evolutionary history in the Hexapoda using over 500 insect transcriptomes, to test the hypothesis that the evolution of holometaboly involved novel isoforms of these genes. All insects appear to express at least one grainyhead and one LSFlike gene, regardless of life cycle, as in most known metazoa. No major evolutionary events in these gene families occurred during the evolution of insects.

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
