Role of PRC2-associated factor EPOP in mouse embryonic stem cells differentiation and early development

Polycomb repressive complex 2 (PRC2) is a key epigenetic regulator of gene expression. It acts through its histone-modifying activity, as it is responsible of di- and trimethylating the tail of histone H3 on lysine 27 (H3K27me2/me3), a mark associated with gene repression. PRC2 activity is highly mo...

PRC2 activity is highly modulated by a number of sub-stoichiometric factors that allow its recruitment to specific target genes through the interaction with RNA, DNA and histone marks; as well as modulation of its enzymatic activity. EPOP is a recently-identified PRC2-associated factor in mouse embryonic stem cells (mESCs), which is necessary to maintain a low level of expression of PRC2 targets, although the result of this regulation is not yet understood.

Actúa a través de su actividad modificadora de histonas, ya que es responsable de di- y tri-metilar la cola de la histona H3 en la lisina 27 (H3K27me2/me3). La presencia de esta marca se asocia con la represión génica. La actividad de PRC2 está altamente modulada por una serie de factores sub-estequiométricos que determinan su reclutamiento a genes específicos a través de la interacción con ARN, ADN e marcas de histonas. Asimismo, pueden modular su actividad enzimática. EPOP es un factor asociado a PRC2 que ha sido recientemente identificado en mESCs (del inglés mouse embryonic stem cells). EPOP es necesario para mantener un bajo nivel de expresión de los genes diana de PRC2, aunque su mecanismo de regulación todavía no ha sido completamente descrito. Con el objetivo de esta tesis es ampliar nuestro conocimiento sobre la regulación génica mediada por EPOP y sus consecuencias, esta tesis investiga el papel de EPOP durante la diferenciación de mESCs, tanto in vitro como in vivoPrograma de doctorat en BiomedicinaUniversitat Pompeu FabraDi Croce, LucianoUniversitat Pompeu Fabra.
