General description

EXOSC2 (Exosome component 2) is a non-catalytic subunit of the eukaryotic RNA exosome. It is localized in the nucleus and in the cytoplasm.


peptide corresponding to the N-terminal region of human EXOSC2, conjugated to KLH. The corresponding sequence is identical in mouse, rat, monkey, bovine, pig and dog.


Anti-EXOSC2 antibody produced in rabbit is suitable for western blot at a concentration of 2.5-5.0μg/mL using whole extracts of human Jurkat, mouse A20 and rat PC12 cells.

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide.

Biochem/physiol Actions

EXOSC2 (Exosome component 2) is associated with several cellular processes such as rRNA processing, RNA degradation from the 3′ end, 3′ to 5′ decay of the mRNA body after its deadenylation. Exosome complex is an ~400kDa multimeric complex, which plays a vital role in substrate recognition. EXOSC2 functions as a cofactor in the maintenance of human exosome integrity and efficient degradation and/or metabolism of various RNA classes.
