Protein Name: Transcription elongation factor A protein 1

UniprotKB/SwissProt ID: Q4KLL0 (Q4KLL0)

Gene Name: Tcea1

Organism: Rattus norvegicus (Rat)

Function: 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 (By similarity)

Protein Subcellular Localization: Nucleus
