Subunit structurei

Component of a nuclear TRAMP-like complex, an ATP-dependent exosome regulatory complex consisting of a helicase (SKIV2L2/MTR4), an oligadenylate polymerase (PAPD5 or PAPD7), and a substrate specific RNA-binding factor (ZCCHC7 or ZCCHC8). Several TRAMP-like complexes exist with specific compositions and are associated with nuclear, or nucleolar RNA exosomes. Identified in the spliceosome C complex.2 Publications
