Background
WTX is a novel gene mutated in a proportion of Wilms' tumors and in patients suffering from sclerosing bone dysplasia. On the molecular level WTX has been shown to act as an antagonist of canonical Wnt/β-catenin signaling in fish and mammals thus linking it to an essential pathway involved in normal development and cancer formation. Interestingly, WTX seems to also localize to an intranuclear component called paraspeckles. In spite of the growing interest of molecular biologists in WTX, little is known about its paralogs and its phylogenetic history.
Results
Using the amino-acid sequence of WTX/AMER1 as a tool for the assignment of orthology and paralogy, we here identify two novel proteins, AMER2 and AMER3, as "WTX" related. This Amer gene family is present in all currently available vertebrate genome sequences, but not invertebrate genomes and is characterized by six conserved blocks of sequences. The phylogenetic analysis suggests that the protoAmer gene originated early in the vertebrate lineage and was then duplicated due to whole genome duplications (WGD) giving rise to the three different Amer genes.
Conclusion
Our study represents the first phylogenetic analysis of Amer genes and reveals a new vertebrate specific gene family that is likely to have played an important role in the evolution of this subphylum. Divergent and conserved molecular functions of Wtx/Amer1, Amer2 and Amer3 are discussed.
Description
This article talks about the family of AMER2, a gene highlighted by Kaushal et al. as having an important methylation profile.
