Target Background

Function
Acts as a mediator between the cap-binding complex (CBC) and both the pre-mRNA splicing and primary microRNAs (miRNAs) processing machinery. Required for proper processing of primary miRNAs to miRNAs, thereby playing a role in RNA-mediated gene silencing (RNAi) by miRNAs. Does not participate in sense post-transcriptional gene silencing. Acts as a regulator of meristem activity and adaxial leaf fate via the miRNA gene-silencing pathway by regulating the expression of PHB and by limiting the competence of shoot tissue to respond to KNOX expression. Its function is however not limited to miRNA-mediated repression of leaf polarity genes, but rather acts as a general regulator of primary microRNAs processing. Also critical for the accumulation of the trans-acting small interfering RNA (ta-siRNA). Required for pre-mRNA splicing.
Gene References into Functions
  1. direct interaction with SE is required for post-transcriptional inhibition of miRNA accumulation by CHR2 but not for its transcriptional activity PMID: 29769717
  2. miRNA863-3p sequentially targets negative immune regulator atypical receptor-like pseudokinases and positive regulator SERRATE upon bacterial infection. PMID: 27108563
  3. Results show that HYL1 and SE directly interact with HIGLE to processes primary transcripts of MIRNA genes into mature miRNAs. PMID: 28321834
  4. Further analysis revealed that the steady state level of HYL1 protein in plants under osmotic stress is dependent on the SnRK2 kinases. Additionally, our results suggest that the SnRK2 kinases physically associate with the miRNA processing components SE and HYL1 and can phosphorylate these proteins in vitro. PMID: 28419088
  5. SERRATE and the nuclear cap-binding protein complex (AtCBC) cooperate in regulation of alternative splicing. PMID: 24137006
  6. The results suggest that the interactions among SERRATE, DICER-LIKE 1 and RNA are a potential point for regulating pri-miRNA processing. PMID: 23921632
  7. SERRATE (SE) is a zinc finger protein that is required for splicing-mediated suppression of RNA silencing in Arabidopsis. PMID: 22112452
  8. Experiments suggest that the non-canonical zinc-finger domain coupled with C-terminal tail of SERRATE binds miRNA precursors. PMID: 21685453
  9. SERRATE acts to coordinately regulate meristem activity and leaf axial patterning PMID: 16222298
  10. SE is a general regulator of miRNA levels affecting the processing of primary miRNA to miRNA. PMID: 16977334
  11. The se-1 mutation in the serrate gene dramatically affects both changes in the leaf development pattern and the response to reduced incident light; virtual plants helped to reveal the combined effects of the multiple changes induced by this mutation. PMID: 17635222
  12. we found that DCL1, HYL1 & SE formed bodies which localized in the nuclei; we were also able to locate the miRNA primary transcript on these bodies; it appears very likely that the observed DCL1-HYL1-SE nuclear body is involved in miRNA production PMID: 17675322
  13. identified SERRATE and confirmed that it is required for organ fusions in cuticular mutants. PMID: 19876373
