Summary: Enables histone deacetylase regulator activity. Involved in positive regulation of gap junction assembly. Acts upstream of or within several processes, including lung alveolus development; positive regulation of skeletal muscle tissue regeneration; and trophectodermal cell differentiation. Located in nucleus. Is expressed in several structures, including central nervous system; heart; lung; trophectoderm; and urinary system. Orthologous to human HOPX (HOP homeobox).

Knock-out of Hopx disrupts stemness and quiescence of hematopoietic stem cells in mice.
Title: Knock-out of Hopx disrupts stemness and quiescence of hematopoietic stem cells in mice.
HOPX expression in cultured ATII cells increased over culture time. HOPX expression was increased in AECs from bleomycin-instilled mouse lungs in vivo. Small interfering RNA-based knockdown of Hopx resulted in suppressing ATII-ATI trans-differentiation and activating cellular proliferation in vitro.
Title: Dynamic expression of HOPX in alveolar epithelial cells reflects injury and repair during the progression of pulmonary fibrosis.
These results support an early priming of neural stem cells (NSCs) for the genesis of defined cell types depending on their spatial location in the subventricular zone and identify HOPX as a marker of a subpopulation primed toward astrocytic fates.
Title: HOPX Defines Heterogeneity of Postnatal Subventricular Zone Neural Stem Cells.
Hopx is required and sufficient, respectively, for basal radial glial cells abundance as found in the developing gyrencephalic neocortex.
Title: A novel population of Hopx-dependent basal radial glial cells in the developing mouse neocortex.
Analysis of the hematopoietic stem/progenitor cell pool in Hopx-/- mice demonstrated significantly reduced cell frequencies and impaired engraftment in competitive repopulation assays, thus providing functional validation of this positional candidate gene

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.
