(A) The events regulating transient spine enlargement can be thought of as modules that regulate key components. (B) The detailed biochemical network shows the interaction between different biochemical species. The network is constructed in modules, where each module contains one key component recognized as a key regulator of dendritic spine volume dynamics. The detailed tables of reactions and parameters are provided in SI Appendix. LCF, lymphocyte chemoattractant factor; MLCK, myosin light chain kinase; MLCP, myosin light chain phosphatase; WASP, Wiskott Aldrich Syndrome protein.
