Ran GTPase expression during early development of the mouse embryo.
Ran is a small GTP-binding protein involved in several essential roles for cell viability. This observation implies Ran might be ubiquitously expressed during development. However, Ran shows a differentiated expression pattern that is restricted to specific tissues from embryo to adult. At early embryonic stages of mouse development we found persistent Ran expression in proliferating neural tissue, neural crest derived dorsal root ganglions and sensory pits. We also showed an accumulation of Ran transcripts in main embryonic haematopoietic tissues: blood islands first and then hepatic bud. In advanced stages of development Ran is also expressed in other tissues showing a high cell turnover.
