Model of the S. macrospora STRIPAK complex. PRO45 and PRO22 associate STRIPAK components to the nuclear envelope, mitochondria, and other internal membrane systems (30), with PRO11 bridging both proteins. SmMOB3 interacts with both PRO45 and PRO11. Phosphatases and kinases in the fungal STRIPAK complex promote dephosphorylation and phosphorylation of target proteins, thereby regulating vegetative growth, hyphal fusion, and sexual propagation.
