actin-binding protein from Salmonella enterica (Mitra
et al, 2000).
SipA shows no obvious homology to any eukaryotic actin-binding protein but binds
actin and also increases the bundling action of fimbrin
by an uncertain mechanism (Zhou
et al, 1999a).
The protein binds actin directly through a C-terminal 226 amino-acid fragment
that increases actin polymerization and decreases depolymerization (Zhou
et al, 1999b).
