it interacts with the exosome complex in the nucleus of eukaryotic cells and is involved in the 3' end processing and degradation of ribosomal rna and snornas. the tramp complex trims the poly(a) tails of rnas destined for rrp6 and the core exosome down to 4-5 adenosines assisting in transcript recognition and exosome complex activation. the substrate specificity of exosomes is improved in the presence of tramp complex as it acts as a crucial cofactor and helps in maintaining various activities.
