βγ‐crystallins are one major component of vertebrate lenses. Here the isolation and characterization of a cDNA, coding for the first βγ‐crystallin molecule from an invertebrate species, the marine sponge Geodia cydonium, is described. The size of the transcript as determined by Northern blotting was 0.7 kb in length. The deduced amino acid sequence consists of 163 aa residues and comprises four repeated motifs which compose the two domains of the βγ‐crystallin. Motif 3 contains the… Expand

Preparation and characterization of geodin
• Biology
• 2005
Geodin appears to be structurally similar in many respects to the bacterial protein S crystallin, with which it also shares a significant, albeit more modest stabilizing effect exerted by calcium ions, suggesting that the crystallin‐type structural scaffold was successfully recruited very early in the evolution of metazoa.

Analysis of sequence searches in the genome of the archaebacterium Methanosarcina acetivorans revealed the presence of a protein annotated as a betagamma-crystallin family protein, named M- Crystallin, which was found to be structurally similar to the vertebrate lens betagmma-Crystallins. Expand
Molecular Evolution of the Metazoan Extracellular Matrix: Cloning and Expression of Structural Proteins from the Demosponges Suberites domuncula and Geodia cydonium
• Medicine, Biology
• Journal of Molecular Evolution
• 2001
The ligand for one of the autopomorphic characters of Metazoa, the single-transmembrane receptor protein with the receptor tyrosine kinase (RTK) from G. cydonium, is identified and it is documented that expression of the fibrous ECM molecule collagen is regulated by the characteristic metazoan morphogens myotrophin and endothelial monocyte-activating polypeptide.

Sponge proteins are more similar to those of Homo sapiens than to Caenorhabditis elegans.
• Biology
• 2000
Sponges are proposed as the reference animals in molecular evolutionary studies of Metazoa because they are the source of the most ancient proteins already present in the common ancestor of all multicellular organisms and some of these proteins were lost later during the evolution of individual animal lineages.

Crystal Structure of the Calcium-Loaded Spherulin 3a Dimer Sheds Light on the Evolution Of the Eye Lens βγ-Crystallin Domain Fold
• Biology
• 2001
Although it is accepted that the vertebrate two-domain βγ-crystallins evolved from a common one-domain ancestor, the mycetezoan single-domain spherulin 3a, with its unique mode of domain pairing, is likely to be an evolutionary offshoot, perhaps from as far back as the one-motif ancestral stage.

The cloning of a gene encoding a βγ-crystallin-type protein from a porifera, the Geodia cydonium sponge, provides direct, conclusive evidence of the existence of such a gene in the genome of an early diverged metazoan. Expand
