The Little Elongation Complex (LEC) (IMAGE) Stowers Institute for Medical Research Caption The little elongation complex (LEC) regulates transcription initiation and elongation of snRNA genes. Shown is a polytene chromosome spread from Drosophila salivary glands ectopically expressing ICE1 (green), the central subunit of LEC that localizes to snRNA genes in both flies and mammals. Actively transcribing RNA polymerase II is shown in red.
