Filamentous fungi are, in some ways, ideal models for human cell transport as they appear to use much of the same transport machinery. However, in filamentous fungi, cellular cargos are often distributed consistently throughout a hyphal network, whereas cargo transport in human cells must be multi-dimensional, comprehensive, and responsive. Correspondingly, human cells have evolved a large series of functionally distinct motors and adaptors. How do these motors and adaptors differ across kingdoms? Are human motors and adaptors ‘variations on a theme’ seen in fungi, or do they perform completely novel cellular roles? Our lab uses filamentous fungi as models to investigate general roles and mechanisms of transport-related proteins, and then uses cellular proteomics and human cell biology to discover how those processes have diverged, expanded, or differ completely in human cells.
