[[http://www.uniprot.org/uniprot/NOT1_YEAST NOT1_YEAST]] Acts as component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. The NOT protein subcomplex negatively regulates the basal and activated transcription of many genes. Preferentially affects TC-type TATA element-dependent transcription. Could directly or indirectly inhibit component(s) of the general transcription machinery.<ref>PMID:9463387</ref> [[http://www.uniprot.org/uniprot/POP2_YEAST POP2_YEAST]] Acts as probably catalytic component of the CCR4-NOT core complex, which in the nucleus seems to be a general transcription factor, and in the cytoplasm the major mRNA deadenylase involved in mRNA turnover. In vitro, POP2 has 3'-exoribonuclease activity with a preference for poly(A) RNAs, but also degrades poly(U) and poly(C) RNAs. Is part of a glucose-sensing system involved in growth control in response to glucose availability.<ref>PMID:9463387</ref> <ref>PMID:11239395</ref> <ref>PMID:11410650</ref> <ref>PMID:14618157</ref>
