Study Reveals Key Genes Drive Protein Diversity in Vertebrates

4/14/2026

Summary

Story summary

Researchers found key developmental genes in vertebrates produced more protein variants via alternative splicing as backboned animals first appeared.
The study led by Professor David Ferrier compared signaling genes in sea squirts, lampreys, and frogs.
It shows vertebrates generate more protein versions, underscoring the importance of distinct protein forms over extra gene copies.
The findings, published in BMC Biology, link these proteins to embryonic development and disease.
