Expansion and intragenic homogenization of spider silk genes since the Triassic: evidence from Mygalomorphae (tarantulas and their kin) spidroins.

Molecular biology and evolution - 1 Nov 2007

Garb Jessica E, DiMauro Teresa, Lewis Randolph V, Hayashi Cheryl Y

Abstract excerpt

Spiders spin a diverse array of silk fibers that are predominately composed of repetitive proteins (spidroins) encoded by a gene family. Characterization of this gene family has focused on spidroins synthesized by the Araneomorphae (true spiders), whereas only a single sequence is known from the Mygalomorphae (tarantulas and their kin). To better understand the diversity and evolution of the spidroin gene family,...
