a

Mutants with altered function are in boldface, and mutants with WT function are in plain type.

b

The “+++,” “++,” and “+” symbols indicate relative band intensities of Western immunoblots of whole-cell lysates.

c

NP, nonpolar; P, polar.

d

+++, WT plaques; ++, small plaques; +, foci; −, no plaques.

e,f

+++, WT N-WASP recruitment/F-actin comet tail formation; ++, 20 to 90% reduction in N-WASP recruitment/F-actin tail formation relative to WT; +, >90% reduction in N-WASP recruitment/F-actin tail formation; +/−, F-actin capping; −, N-WASP/F-actin tail formation not detected; NT, not tested. Quantitated as detailed in Materials and Methods.
