Research Abstract

We have performed functional analysis on Goliath(Gol), a novel regulator of Wnt signaling. We have identified an E2 ubiquitin conjugating enzyme which binds to the RING domain of Gol. In addition, by searching for the PA domain-binding proteins, some putative substrates of Gol have also been found. To elucidate in vivo function of Gol, we have generated a Drosophila line in which the gol gene was deleted.
