Abstract:
It was found in the last decade that gene regulation in the level of translation is
mainly effected by the initiation process. Eukaryotic initiation factors (eIF-) 2 and
4 are the main components that regulate gene expression, by enabling the 40S
ribosomal subunit structure to bind to a pre-initiation complex eIF-4F. This process
is complex and involves many different regulating components. This paper pres-
ents models for the eIF-2 and -4 regulation processes. A further simplification of
the eIF-2 process is presented and nonlinear analysis proves L2 stability of the
process. Simulations and analysis of the reduced model led to several conclusions
about the affect of a few principle factors in the eIF-2 initiation process (namely
eIF-2B, phosphorylated and non-phosphorylated eIF-2_ and GCN2), consistent
