A role for rab7 GTPase in growth factor-regulated cell nutrition and apoptosis.
When growth factors are removed from many mammalian cells, growth ceases and apoptosis is induced. The small GTPase rab7, which regulates endocytic membrane traffic, participates in this process by mediating the regulated internalization and degradation of nutrient transporters. This process triggers nutrient starvation that helps to induce cell death.
