Discovery of mammalian collagens I and III within ancient poriferan biopolymer spongin [PDF]

Nature Communications
Spongin is a fundamental biopolymer that has played a crucial role in the skeletogenesis of keratosan sponges for over 800 million years. This biomaterial had so far remained chemically unidentified and believed to be an enigmatic type of halogenated ...
