CC -!- FUNCTION: Mesodermal transcription factor that plays a key role in
CC somitogenesis and is specifically required for sclerotome development.
CC Required for maintenance of the sclerotome polarity and formation of
CC the cranio-cervical joints (PubMed:19520072). Binds specifically to the
CC promoter of target genes and regulates their expression. Activates
CC expression of NKX3-2 in the sclerotome (PubMed:15024065). Activates
CC expression of CDKN1A and CDKN2A in endothelial cells, acting as a
CC regulator of vascular cell proliferation. While it activates CDKN1A in
CC a DNA-dependent manner, it activates CDKN2A in a DNA-independent manner
CC (PubMed:22206000). Required for hematopoietic stem cell (HSCs)
CC induction via its role in somitogenesis: specification of HSCs occurs
CC via the deployment of a specific endothelial precursor population,
CC which arises within a sub-compartment of the somite named endotome (By
CC similarity). {ECO:0000250|UniProtKB:F1Q4R9,
CC ECO:0000269|PubMed:12925591, ECO:0000269|PubMed:1363541,

CC ECO:0000269|PubMed:22206000}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:22206000}. Cytoplasm
CC {ECO:0000269|PubMed:22206000}. Note=Localizes predominantly in the
CC nucleus. {ECO:0000269|PubMed:22206000}.
CC -!- TISSUE SPECIFICITY: Heart, lateral plate derivatives, kidney, loose
CC connective tissue at sites of bone formation and skeletal muscle-
CC connective tissue apposition. {ECO:0000269|PubMed:1363541}.
CC -!- DEVELOPMENTAL STAGE: After 7 dpc it is expressed in mesoderm lying
CC posterior of the future primordial head and heart. Between 7.5 and 9.5
CC dpc it is expressed in presomitic mesoderm, epithelial and
CC differentiating somites and in lateral plate mesoderm. In the body of
CC mid-gestation embryos it is restricted to loose undifferentiated
CC mesenchyme. {ECO:0000269|PubMed:1363541}.
CC -!- DISRUPTION PHENOTYPE: Mice display mild defects in sclerotome derived
CC vertebral and rib bones (PubMed:12925591). Abnormalities are restricted
CC to the sclerotome and its derivatives and are characterized by a
CC remodeling of the cranio-cervical joints, leading to the assimilation
CC of the atlas into the basioccipital bone so that the skull rests on the
CC axis (PubMed:19520072). Mice lacking Meox1 and Meox2 show extremely
CC disrupted somite morphogenesis, patterning and differentiation. They
CC lack an axial skeleton and skeletal muscles are severely deficient
CC (PubMed:12925591). {ECO:0000269|PubMed:12925591,
CC ECO:0000269|PubMed:19520072}.
