Target Background

Function
RNA-binding protein that recognizes and binds N6-methyladenosine (m6A)-containing RNAs, a modification present at internal sites of mRNAs and some non-coding RNAs. Functions alone and as part of the erh1-mmi1 complex, to recruit the CCR4-NOT complex and the NURS complex to target RNAs. Suppresses the meiotic program during vegetative growth and promotes the meiotic program during mating. Binds to DSR (determinant of selective removal) regions in meiotic mRNA, and recruits the NURS complex to targets. Recruitment of NURS complex to target mRNAs promotes mRNA decay by engagement of the nuclear exosome, and formation of heterochromatin islands at meiotic genes silenced by the exosome. Recruitment of the CCR4-NOT complex to target RNAs promotes heterochromatin formation at RNAi-dependent heterochromatin domains (HOODs), including a subset of meiotic genes, lncRNAs and retrotransposons. Recruitment of the CCR4-NOT complex to rDNA promotes rDNA heterochromatin assembly. Promotes non-canonical transcription termination at meiotic genes and prevents lncRNA transcription from invading and repressing adjacent genes.
Gene References into Functions
  1. The authors propose that Mmi1 recruits the Ccr4-Not complex to counteract its own inhibitor Mei2, thereby locking the system in a stable state that ensures the repression of the meiotic program by Mmi1. PMID: 28841135
  2. Mmi1 can recognize and bind a class of meiosis-specific transcripts expressed inappropriately in mitotic cells; structural insights into the specific recognition of these mRNAs by the YTH domain containing protein Mmi1 have been presented. PMID: 28735863
  3. report the 1.75 A crystal structure of the Mmi1 YTH domain and provide evidence that Mmi1 recognizes DSR RNA via a binding mode distinct from that of structurally homologous YTH proteins that recognize m(6)A-modified RNA PMID: 27165520
  4. Erh1 and the RNA-binding protein Mmi1 form a stoichiometric complex, called the Erh1-Mmi1 complex (EMC), to promote meiotic mRNA decay and facultative heterochromatin assembly. PMID: 26942678
  5. Mmi1 YTH domain selectively recognizes the determinant of selective removal RNA motif. PMID: 26673708
  6. Mmi1 can specifically regulate the splicing of particular introns in a transcript: it inhibits the splicing of introns that are in the vicinity of putative Mmi1 binding sites, while allowing the splicing of other introns that are far from such sites. PMID: 22046364
  7. Mei2 tethers Mmi1 and thereby stabilizes the transcripts necessary for the progression of meiosis PMID: 20948174
