Before revision: Activation cascades are prevalent in cell signalling mechanisms . We study the classic model of linear activation cascades and find that in special but important cases the output of an entire cascade can be represented analytically as a function of the input and a lower incomplete gamma function.
After revision: Activation cascades are a prevalent feature in cellular mechanisms for signal transduction. Here we study the classic model of linear activation cascades and find that in special but important cases the output of an entire cascade can be represented analytically as a function of the input and a lower incomplete gamma function.
