Figure 2. CsiV is a periplasmic protein of unknown function.

(A) Domain architecture of CsiV (VC1887). The signal sequence is predicted to be cleaved off between A30 and R31. DUF2803 is not associated with any function. (B) Fluorescence microscopy analysis of V. cholerae producing plasmid-encoded CsiV-mCherry, a functional fusion protein that localizes to the cell periphery. Scale bar = 5 µm.
