Description			Necessary for efficient RNA polymerase II transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by S-II allows the resumption of elongation from the new 3'-terminus. Source: Recombinant protein corresponding to aa1-299 from human TCEA2, fused to His-SUMO-Tag at N-terminal expressed in E. coli.
