一种扩展的Post类函数及其对基因调控机制的影响
The Study of an Extended Post CIass Functions and its InfIuence on the Gene Regu Iatory Mechanis m
摘要
Abstract
Theoretical analysis reveals that ordered functions play an important role in the running and dynamical be-havior of networks.Post function class has been known as the maximal ordered function.However,it only describes the posi-tive regulatory mechanism appeared in genetic regulatory networks.In this paper,we extend the Post function class so that it contains both the positive and negative regulatory mechanism.Simulation results show that the extended Post function class can present similar dynamical characters as the original Post class and Canalizing function class.It has the ability to keep or-dered behaviors and can emerge the long-range correlated dynamics.From the point of view of natural evolution,we con-clude that such abundant ordered functions are more possible to be selected as the interactions among genes.Finally,the dis-tribution of function classes on eight real systems also partially supports our conclusion.关键词
