Target Background

Function
Polycomb group (PcG) protein. Catalytic subunit of some PcG multiprotein complex, which methylates 'Lys-27' of histone H3, leading to transcriptional repression of the affected target genes. Required to prevent the proliferation of the central cell of the female gametophyte by repressing target genes before fertilization. After fertilization, it probably also regulates the embryo and endosperm proliferation and anteroposterior organization during seed development. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. Interacts with the promoter and repress the transcription of genes such as PHE1 and PHE2, that are paternally active and maternally silenced genes.
Gene References into Functions
  1. TAF13 functions together with MEDEA and SWINGER, both members of a plant variant of Polycomb Repressive Complex 2 (PRC2)in transcriptional regulation during seed development. [MEDEA] PMID: 23506837
  2. functional requirement of the FIS-PRC2 is to balance parental genome contributions and to reduce genetic conflict. PMID: 23326241
  3. imprinted MEA expression mediated by this ICR is independent of DME and MET1, consistent with the lack of any significant DNA methylation in this region PMID: 22855791
  4. Parent-of-origin-specific expression of the Polycomb group (PcG) gene MEDEA is causally responsible for seed developmental aberrations in Arabidopsis seeds with increased paternal genome contributions. PMID: 19779546
  5. MEA imprinting is regulated by histone methylation. PMID: 16527743
  6. MEA-FIE PcG complex implies distinct functions that are dynamically regulated during reproduction. PMID: 16651654
  7. MEA and SWN perform partially redundant functions in controlling the initiation of endosperm development before fertilization in Arabidopsis. PMID: 16924116
  8. The evolution of MEA suggests a late origin of genomic imprinting within the Brassicaceae, whereas imprinting is thought to have originated early within the mammalian lineage PMID: 17637669
  9. Study presents data and analyses of sequence diversity of MEA in self-fertilizing and outcrossing Arabidopsis and its relatives, to help clarify the form of selection acting on this gene. PMID: 19126870
