Heat shock factors (HSFs) are transcriptional regulators that play a crucial role in the cellular response to environmental stress, particularly heat stress. Understanding the evolution of HSFs can provide insights into the adaptation of organisms to their changing environments. This project explored the evolution of HSFs within tetrapods, a group of animals that includes amphibians, reptiles, turtles, and mammals. Through an analysis of the available genomic data and subsequent genomic methodologies, HSFs have undergone significant changes throughout tetrapod evolution, as evidenced by loss events observed in protein sequences of the species under examination. Moreover, several conserved and divergent regions within HSF proteins were identified, which may reflect functional differences between HSFs in different tetrapod lineages. Our findings suggest that the evolution of HSFs has contributed to the adaptation of tetrapods to their diverse environments and that further research on the functional and regulatory differences between HSFs may provide a better understanding of how organisms cope with stress in heat-stressed environments.
