  This manuscript uses a statistical mechanical approach to study the effect of
the adhesion, through MOCA protein, on cell locomotion. The MOCA protein
regulates cell-cell adhesion, and we explore its potential role in the cell
movement. We present a series of statistical descriptions of the motion in
order to characterize the cell movement, and found that MOCA affects the
statistical scenario of cell locomotion. In particular, we observe that MOCA
enhances the tendency of joint motion, inhibits super-diffusion, and decreases
overall cell motion. These facts are compatible with the hypothesis that the
cells move faster in a less cohesive environment. Furthermore, we observe that
velocity distribution tails are longer than those predicted by
Maxwell-Boltzmann in all cases studied here, indicating that cell movement is
more complex than that of a liquid.
