Mox-1 protein is first detected in newly formed mesoderm of primitive streak stage mouse embryos (7.5 dpc), earlier than Mox-2 (9.0 dpc), and is also expressed in branchial arches and limbs, indicating distinct developmental roles for Mox-1 and Mox-2. |

Meox1 loss-of-function in mice disrupts sclerotome rostro-caudal polarity, causing assimilation of the atlas into the basioccipital bone; MEOX1 protein occupies conserved promoter regions of Tbx18 and Uncx transcription factor genes, and Meox1 mutants show altered Tbx18, Uncx, and Bapx1 expression, indicating Meox1 directly regulates these genes to maintain sclerotome polarity. |

MEOX1 is a direct transcriptional target of Hoxa2; Hoxa2 binds to the Meox1 proximal promoter via two conserved binding sites required for Hoxa2-dependent activation, and Meox1 can bind DNA sequences recognized by Hoxa2 on its functional target genes, placing Meox1 downstream of Hoxa2 in the branchial arch regulatory network. |

MEOX1 activates p21(CIP1/WAF1) and p16(INK4a) expression in vascular endothelial cells and induces cell cycle arrest and senescence; MEOX1 activates p16(INK4a) in a DNA binding-dependent manner, whereas it induces p21(CIP1/WAF1) in a DNA binding-independent manner, distinguishing its mechanism from MEOX2. |

Meox1 specifies endotomal endothelial precursor cells within the zebrafish somite; loss of meox1 expands the endotome at the expense of muscle precursors and increases the number of endotome-derived cells colonizing the dorsal aorta, leading to increased chemokine-dependent haematopoietic stem cell induction. |
