Summary
New proteins with novel functions arise from gene duplication and divergence. This study reveals how related transcription factors evolve to control new genes and cellular functions.
Area of Science:
- Genomics
- Molecular Biology
- Evolutionary Biology
Background:
- Protein evolution is crucial for developing novel cellular functions.
- Gene duplication and divergence are primary mechanisms driving this process.
Purpose of the Study:
- To identify molecular mechanisms underlying transcription factor divergence.
- To understand how these evolved factors control new gene sets and cellular functions.
Main Methods:
- Comparative genomic analysis.
- Molecular evolution studies.
- Functional assays to assess transcription factor activity.
Main Results:
- Several molecular mechanisms were identified that enable transcription factor divergence.
- Evolved transcription factors were shown to regulate distinct sets of target genes.
- These changes enable the acquisition of novel cellular functions.
Conclusions:
- Transcription factor evolution is a key driver of genomic innovation.
- Understanding these divergence mechanisms provides insight into the emergence of new biological capabilities.

6.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.

The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
