摘要：

Rab7 is a small GTPase that plays a crucial role in the regulation of transport from early to late endosomes and lysosomes, phagosome maturation and in lysosomal biogenesis in mammalian cells. It contains conserved and unique sequence elements that mediate its function. Two Rab7 genes, Rab7a (703 bp) and Rab7b (707 bp) were identified in the unicellular eukaryote Paramecium by PCR...
