Genomic survey uncovers evolutionary origins of secretoglobins
At a conference in Washington D.C. in 2000, the secretoglobin super family of proteins was named to classify proteins with structural similarities to its founding member uteroglobin. Now, 25 years later, there is still little known about the basic functions of these proteins, prompting a group of researchers to dive into their evolutionary origins. This bioinformatic survey reported that secretoglobins, or SCGBs -- originally thought to be exclusive to mammals -- are also found in turtles, crocodilians, lizards, and birds. These new findings suggest that these proteins evolved earlier than dinosaurs and share a basic function that is not yet discovered.
