      abstract     = {Rod-like and banana-shaped proteins, like BAR-domain
                      proteins and MreB proteins, adsorb on membranes and regulate
                      the membrane curvature. The formation of large filamentous
                      complexes of these proteins plays an important role in
                      cellular processes like membrane trafficking, cytokinesis
                      and cell motion. We propose a simplified model to
                      investigate such curvature-dependent self-assembly
                      processes. Anisotropic building blocks, modeled as trimer
                      molecules, which have a preferred binding site, interact via
                      pair-wise Lennard-Jones potentials. When several trimers
                      assemble, they form an elastic ribbon with an intrinsic
                      curvature and twist, controlled by bending and torsional
                      rigidity. For trimer self-assembly on the curved surface of
                      a cylindrical membrane, this leads to a preferred spatial
                      orientation of the ribbon. We show that these interactions
                      can lead to the formation of helices with several windings
                      around the cylinder. The emerging helix angle and pitch
                      depend on the rigidities and the intrinsic curvature and
                      twist values. In particular, a well-defined and controllable
                      helix angle emerges in the case of equal bending and
                      torsional rigidity. The dynamics of filament growth is
                      characterized by three regimes, in which filament length
                      increases with the power laws tz in time, with z ≃ 3/4, z
                      = 1/2, and z = 0 for short, intermediate, and long times,
                      respectively. A comparison with the solutions of the
                      Smoluchowski aggregation equation allows the identification
                      of the underlying mechanism in the short-time regime as a
                      crossover from size-independent to diffusion-limited
                      aggregation. Thus, helical structures, as often observed in
                      biology, can arise by self-assembly of anisotropic and
                      chiral proteins.},
