This gene is a member of the septin family of GTPases.
Members of this family are required for cytokinesis. One version of
pediatric acute myeloid leukemia is the result of a reciprocal
translocation between chromosomes 11 and X, with the breakpoint
associated with the genes encoding the mixed-lineage leukemia and
septin 2 proteins. This gene encodes four transcript variants
encoding three distinct isoforms. An additional transcript variant
has been identified, but its biological validity has not been
determined.
