Model input

A short description, the input parameters and output data are explained for the four submodels below:

Linker Simulation (Distance).

This model calculates the effect of the linker on the distance between the intracellular domains. It's output file consists of a list of numbers. Each number represents the distance between the intracellular domains that was calculated in one iteration. The input parameters and used values to obtain our results are shown below:

Parameters.

• Length of Linker (nm): The contour length of the modeled linker in nanometers. The value we used for our simulation was 28.4 nm; the linker consists of 71 amino acids that each have a contour length of 0.4 nm [1]
• Persistence Length of Linker (nm): The persistence length that is characteristic for the used material. The value we used to simulate our peptide linker was 0.45 nm [2]
• Radii of the tethered particles (nm): The radii of the two intracellular domains that are tethered to their membrane protein. We filled in 3 nm for both our first domain (Nanoluc) and our second (mNeongreen). These values were measured using PDB files. For Nanoluc a PDB was used that represents a model of the real structure. For mNeongreen, a single beta barrel in the PDB file 4HVF was used. This PDB file describes the x-ray diffraction structure of lanGFP, a relative of lanYFP, the protein which was mutated to mNeongreen. [3]
