Mrj(-/-) chorions at embryonic day 8.5 have expanded Rhox4b expression domains and do not form normal layers of gene expression suggesting that chorion patterning requires Mrj.
Title: Cell-cell adhesion defects in Mrj mutant trophoblast cells are associated with failure to pattern the chorion during early placental development.
Data show that Mrj(-/-) embryos exhibit neural tube defects independent of the placenta phenotype, including exencephaly and thin-walled neural tubes, and suggest that Mrj plays an important role in neural stem cell self-renewal.
Title: Neural stem cell self-renewal requires the Mrj co-chaperone.
DnaJB6 is necessary for translocation of Slfn1 into the nucleus, where Slfn1 down-regulates cyclin D1, induces cell-cycle arrest and programmes a quiescent state of T-cells
Title: The Hsp40 family chaperone protein DnaJB6 enhances Schlafen1 nuclear localization which is critical for promotion of cell-cycle arrest in T-cells.
Study demonstrates here that, in the developing placenta of the mouse, the absence of the Mrj co-chaperone prevents proteasome degradation of keratin 18 intermediate filaments, resulting in the formation of keratin inclusion bodies.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
