3'-5' exoribonuclease CSL4 homolog is an enzyme that in humans is encoded by the EXOSC1gene.[1][2][3]
This gene encodes a core component of the exosome complex. The mammalian exosome is required for rapid degradation of AU rich element-containing RNAs but not for poly(A) shortening. The association of this protein with the exosome is mediated by protein-protein interactions with ribosomal RNA-processing protein 42 and ribosomal RNA-processing protein 46.[3]
