Homology model of the Drosophila Nanos zinc-finger domain. (A) Electrostatic potential of dmNanos319–372 depicted on the molecular surface. Blue and red surfaces indicate positive and negative potential, respectively. (B) Missense mutations causing a strong phenotype in D. melanogaster, shown in magenta on the molecular surface of dmNanos319–372. dmNanos, Drosophila melanogaster Nanos.
