Transcription factor that plays a key role in chondrocytes differentiation and skeletal development (PubMed:24038782).

Specifically binds the 5'-ACAAAG-3' DNA motif present in enhancers and super-enhancers and promotes expression of genes important for chondrogenesis, including cartilage matrix protein-coding genes COL2A1, COL4A2, COL9A1, COL11A2 and ACAN, SOX5 and SOX6 (PubMed:8640233).

Also binds to some promoter regions (By similarity).

Plays a central role in successive steps of chondrocyte differentiation (By similarity).

Absolutely required for precartilaginous condensation, the first step in chondrogenesis during which skeletal progenitors differentiate into prechondrocytes (By similarity).

Together with SOX5 and SOX6, required for overt chondrogenesis when condensed prechondrocytes differentiate into early stage chondrocytes, the second step in chondrogenesis (By similarity).

Later, required to direct hypertrophic maturation and block osteoblast differentiation of growth plate chondrocytes: maintains chondrocyte columnar proliferation, delays prehypertrophy and then prevents osteoblastic differentiation of chondrocytes by lowering beta-catenin (CTNNB1) signaling and RUNX2 expression (By similarity).

Also required for chondrocyte hypertrophy, both indirectly, by keeping the lineage fate of chondrocytes, and directly, by remaining present in upper hypertrophic cells and transactivating COL10A1 along with MEF2C (By similarity).

Low lipid levels are the main nutritional determinant for chondrogenic commitment of skeletal progenitor cells: when lipids levels are low, FOXO (FOXO1 and FOXO3) transcription factors promote expression of SOX9, which induces chondrogenic commitment and suppresses fatty acid oxidation (By similarity).

Mechanistically, helps, but is not required, to remove epigenetic signatures of transcriptional repression and deposit active promoter and enhancer marks at chondrocyte-specific genes (By similarity).

Acts in cooperation with the Hedgehog pathway-dependent GLI (GLI1 and GLI3) transcription factors (By similarity).

In addition to cartilage development, also acts as a regulator of proliferation and differentiation in epithelial stem/progenitor cells: involved in the lung epithelium during branching morphogenesis, by balancing proliferation and differentiation and regulating the extracellular matrix (By similarity).

Controls epithelial branching during kidney development (By similarity).

Campomelic dysplasia (CMD1)14 Publications
The disease is caused by variants affecting the gene represented in this entry.
Disease descriptionA rare, often lethal, osteochondrodysplasia characterized by congenital bowing and angulation of long bones. Other skeletal defects include unusually small scapula, deformed pelvis and spine, and a missing pair of ribs. Craniofacial and ear defects are common. Most patients die soon after birth due to respiratory distress which has been attributed to hypoplasia of the tracheobronchial cartilage and small thoracic cage. Up to two-thirds of affected XY individuals have genital defects or may develop as phenotypic females.

Acetylated; acetylation impairs nuclear localization and ability to transactivate expression of target genes. Deacetylated by SIRT1.By similarity
Phosphorylation at Ser-64 and Ser-211 by PKA increases transcriptional activity and may help delay chondrocyte maturation downstream of PTHLH/PTHrP signaling. Phosphorylation at either Ser-64 or Ser-211 is required for sumoylation, but phosphorylation is not dependent on sumoylation. Phosphorylated on tyrosine residues; tyrosine dephosphorylation by PTPN11/SHP2 blocks SOX9 phosphorylation by PKA and subsequent SUMOylation.By similarity

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i9289CFBB8D6631A2
