Comments concerning this interaction

The seven amino acid deletion of NTLAHYG (aa 1722-1728) does not interfere with PlexB interaction with Rho1.

(Hu et al., 2001)

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey produced and labeled by in vitro translation.
