An expression sequence tag identified in a screen for genes upregulated by retinoic acid induced neuronal differentiation of the human teratocarcinoma cell line Ntera2/D1 was found in close genomic proximity to a region of high sequence homology to the septin subfamily of GTPase genes. We could show that the tag corresponds to the 3' untranslated region of this novel gene named septin 3 and cloned three isoforms A (2191 bp), B (4378 bp), and C (1896 bp) from human Ntera2/D1 cDNA. We present the genomic localization and organization on chromosome 22q13.2, a chromosomal hot spot for translocations implicated in leukemia. Interestingly, MSF the closest paralog of septin 3 is a fusion partner in a therapy-related acute myeloid leukemia. Quantitative PCR confirmed the upregulation of the putative septin by neuronal differentiation and northern blotting showed only one band corresponding to sep3B with a neurospecific expression pattern in adult human tissues.
