An intron-less betagamma-crystallin-type gene from the sponge Geodia cydonium.

We report the cloning of a gene encoding a betagamma-crystallin-type protein from a porifera, the Geodia cydonium sponge. The data provide direct, conclusive evidence of the existence of such a gene in the genome of an early diverged metazoan. The cloned gene is found to contain no introns, while proto-splice sites are identified in the nucleotide sequence… CONTINUE READING
