title: Darkness descends with two Rabs.
abstract: Over 60 distinct Rab GTPases regulate specific vesicular transport steps in the mammalian central vacuolar system. Wasmeier et al. (this issue, p. 271) reveal a redundant role for two tissue-specific Rab proteins in regulating transport to a tissue-specific lysosome-related organelle, the melanosome.
