General description

The EXOSC1 gene is located on human chromosome 10q24.1.

The gene EXOSC1 (exosome component 1) encodes one of the nine core subunits of the exosome complex. The protein is also referred to as Csl4 and has high affinity for RNA.


Anti-EXOSC1 recognizes human EXOSC1.


peptide corresponding to a sequence at the N-terminal region of human EXOSC1, conjugated to KLH. The corresponding sequence is identical in mouse, rat, monkey, bovine and dog.


Anti-EXOSC1 antibody produced in rabbit may be used in immunoblotting and immunofluorescence.

Physical form

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

Storage and Stability

For continuous use, store at 2-8°C for up to one month. For extended storage freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

Biochem/physiol Actions

The exosome complex facilitates the splicing and degradation of mRNAs and non-coding RNAs. It is also essential for epigenetic gene regulation. It endogenously suppresses erythroid maturation. Within the complex, Exosc1 (exosome component 1) associates with Exosc6 to stabilize the complex. The binding of Exosc10 to Exosc1, Exosc6, and Exosc8 enhances the activity of the complex and positions Exosc1 for RNA binding.
