Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Transcription factor required for zygotic genome activation (ZGA), a critical event in early embryonic development during which the developmental control passes from maternally provided mRNAs to the expression of the zygotic genome after fertilization (PubMed:37459895). Together with other Obox family members, required in early two-cell stage embryos to kick-start the major ZGA wave by facilitating RNA Polymerase II 'pre-configuration', during which RNA Polymerase II relocates from the initial one-cell stage binding targets to ZGA gene promoters and distal enhancers (PubMed:37459895). Mechanistically, promotes recruitment of RNA Polymerase II from (CG-rich) non-ZGA genes to (CG-poor) ZGA genes at the two-cell stage (PubMed:37459895). Binds to regulatory DNA sequences containing a 5'-ACNCCTTTAATCCCAG-3' sequence motif (PubMed:37459895). Most maternal and zygotic Obox family proteins can compensate for one another (PubMed:37459895).SUBCELLULAR LOCATION Specifically expressed in early embryos.DEVELOPMENTAL STAGE Expressed zygotically with expression starting at mid-two-cell stage, during major zygotic genome activation (ZGA), and peaking in late two-cell stage embryos.DISRUPTION PHENOTYPE No visible phenotype; mice are viable and fertile (PubMed:37459895). Female mice lacking maternally transcribed Obox1, Obox2, Obox5, Obox7 as well as zygotically expressed Obox3 and Obox4 are infertile: embryos arrest at two-four cell stage due to impaired zygotic genome activation (ZGA) (PubMed:37459895).SIMILARITY Belongs to the paired homeobox family. Obox subfamily.
