Peroxisomal motility and interaction with microtubules

Recent in vivo observations have revealed that peroxisomes are more dynamic and interactive than previously assumed. The growing recognition of the tubular and reticular morphology of peroxisomes in living cells, their association with microtubules, and the dynamic movements of peroxisomes,in Vivo and in vitro have inspired the query into the investigation of the, cellular machinery that mediates such a complex behaviour. The characterisation. of the underlying molecular components of this machinery is providing insight into: the mechanisms regulating peroxisomal morphology and intracellular distribution.
