The full-length cDNA encoding Rab23, a novel Ras-related small GTPase, was isolated using the sequence of a previously described [Chavrier et al., Gene 112 (1992) 261-264] short cDNA fragment and the rapid amplification of cDNA ends (RACE) PCR techniques. The deduced amino acid sequence was not very closely related to any previously described small GTPase, but was within the Rab subfamily. A Northern analysis revealed that the rab23 mRNA is predominantly expressed in the brain, which places the protein, together with Rab3a and Rab15, in the group of small GTPases characteristic of the nervous system.
