Phylogenetic and evolutionary relationships and developmental expression patterns of the zebrafish twist gene family

Abstract

Four members of the twist gene family (twist1a, 1b, 2, and 3) are found in the zebrafish, and they are thought to have arisen through three rounds of gene duplication, two of which occurred prior to the tetrapod-fish split. Phylogenetic analysis groups most of the vertebrate Twist1 peptides into clade I, except for the Twist1b proteins of the… (More)
