Structural shifts of aldehyde dehydrogenase enzymes were instrumental for the early evolution of retinoid-dependent axial patterning in metazoans
(NATL ACAD SCIENCES, 2011)
Aldehyde dehydrogenases (ALDHs) catabolize toxic aldehydes and process the vitamin A-derived retinaldehyde into retinoic acid (RA), a small diffusible molecule and a pivotal chordate morphogen. In this study, we combine ...
The role of exon shuffling in shaping protein-protein interaction networks
(BIOMED CENTRAL LTD, 2010)
Background: Physical protein-protein interaction (PPI) is a critical phenomenon for the function of most proteins in living organisms and a significant fraction of PPIs are the result of domain-domain interactions. Exon ...
Major features of protistan evolution: controversies, problems and a few answers

Evolution of Precambrian life in the Brazilian geological record
(CAMBRIDGE UNIV PRESSNEW YORK, 2012)
Precambrian rocks comprise nearly one-quarter of the surface of Brazil and range from Paleoarchean (ca. 3.6 Ga) to the latest Ediacaran (0.542 Ga) in age. Except for controversial phosphatized 'embryo-like' microfossils ...
Oscheius tipulae as an example of eEF1A gene diversity in nematodes
(SPRINGER, 2008)
We characterized four eEF1A genes in the alternative rhabditid nematode model organism Oscheius tipulae. This is twice the copy number of eEF1A genes in C. elegans, C. briggsae, and, probably, many other free-living and ...
Ediacaran metazoan fossil record from South America and its implications in the studies about origin and complexification of animal lifeO registro fossilífero de metazoários ediacaranos na América do Sul e suas implicações nos estudos sobre origem e complexificação da vida animal

Curupira-1 and Curupira-2, two novel Mutator-like DNA transposons from the genomes of human parasites Schistosoma mansoni and Schistosoma japonicum
(CAMBRIDGE UNIV PRESS, 2011)
Transposons of the Mutator superfamily have been widely described in plants, but only recently have metazoan organisms been shown to harbour them. In this work we describe novel Mutator superfamily transposons from the ...
Integrative view of α2,3-sialyltransferases (ST3Gal) molecular and functional evolution in deuterostomes: significance of lineage-specific losses
(Oxford University Press, 2014-12)
Sialyltransferases are responsible for the synthesis of a diverse range of sialoglycoconjugates predicted to be pivotal to deuterostomes' evolution. In this work, we reconstructed the evolutionary history of the metazoan ...
