Poxviruses taking a ride on actin: new users of known hardware.
Vaccinia virus uses A36 to recruit the actin polymerization effectors Nck and N-WASP to drive actin tail formation. Now, Dodding and Way identify functional orthologs of A36 in other vertebrate poxviruses that harbor varying numbers of Nck-binding sites and can substitute for A36 despite no sequence homology.
