Functioni

Mesodermal transcription factor that plays a key role in somitogenesis and is specifically required for sclerotome development. Required for maintenance of the sclerotome polarity and formation of the cranio-cervical joints (PubMed:19520072). Binds specifically to the promoter of target genes and regulates their expression. Activates expression of NKX3-2 in the sclerotome (PubMed:15024065). Activates expression of CDKN1A and CDKN2A in endothelial cells, acting as a regulator of vascular cell proliferation. While it activates CDKN1A in a DNA-dependent manner, it activates CDKN2A in a DNA-independent manner (PubMed:22206000). Required for hematopoietic stem cell (HSCs) induction via its role in somitogenesis: specification of HSCs occurs via the deployment of a specific endothelial precursor population, which arises within a sub-compartment of the somite named endotome (By similarity).By similarity7 Publications

Pathology & Biotechi

Disruption phenotypei

Mice display mild defects in sclerotome derived vertebral and rib bones (PubMed:12925591). Abnormalities are restricted to the sclerotome and its derivatives and are characterized by a remodeling of the cranio-cervical joints, leading to the assimilation of the atlas into the basioccipital bone so that the skull rests on the axis (PubMed:19520072). Mice lacking Meox1 and Meox2 show extremely disrupted somite morphogenesis, patterning and differentiation. They lack an axial skeleton and skeletal muscles are severely deficient (PubMed:12925591).2 Publications

Developmental stagei

After 7 dpc it is expressed in mesoderm lying posterior of the future primordial head and heart. Between 7.5 and 9.5 dpc it is expressed in presomitic mesoderm, epithelial and differentiating somites and in lateral plate mesoderm. In the body of mid-gestation embryos it is restricted to loose undifferentiated mesenchyme.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
