Component of the little elongation complex (LEC), a complex required to regulate small nuclear RNA (snRNA) gene transcription by RNA polymerase II and III (PubMed:22195968, PubMed:23932780). Specifically acts as a scaffold protein that promotes the LEC complex formation and recruitment and RNA polymerase II occupancy at snRNA genes in subnuclear bodies (PubMed:23932780). Component of the little elongation complex (LEC), at least composed of ELL (ELL, ELL2 or ELL3), ZC3H8, ICE1 and ICE2. Interacts (via N-terminus domain) with ELL. Interacts (via C-terminus domain) with ICE2 and ZC3H8. Colocalizes with COIL in subnuclear Cajal and histone locus bodies. Associates to transcriptionally active chromatin at snRNA genes. The N-termimus domain is necessary and sufficient for its targeting to subnuclear cajal and histone locus bodies. Belongs to the ICE1 family. Extended N-terminus. Aberrant splicing. Truncated N-terminus. Truncated C-terminus.
