The encoded protein may regulate chondrogenesis by inhibiting transforming growth factor-beta 1-induced gene expression in cartilage. This protein also binds collagen and calcium and may induce collagen mineralization. Polymorphisms in the aspartic acid repeat region of this gene are associated with a susceptibility to osteoarthritis, and also with intervertebral disc disease. Alternative splicing of this gene results in multiple transcript variants.[provided by RefSeq, Jul 2014]. * **<color #00a2e8>UniProt Summary</color>**: Negatively regulates periodontal ligament (PDL) differentiation and mineralization to ensure that the PDL is not ossified and to maintain homeostasis of the tooth-supporting system. Inhibits BMP2-induced cytodifferentiation of PDL cells by preventing its binding to BMPR1B/BMP type-1B receptor, resulting in inhibition of BMP-dependent activation of SMAD proteins (By similarity). Critical regulator of TGF-beta in articular cartilage and plays an essential role in cartilage homeostasis and osteoarthritis (OA) pathogenesis. Negatively regulates chondrogenesis in the articular cartilage by blocking the TGF- beta/receptor interaction on the cell surface and inhibiting the canonical TGF-beta/Smad signal. Binds calcium and plays a role in osteoblast-driven collagen biomineralization activity. {ECO:0000250, ECO:0000269|PubMed:17827158, ECO:0000269|PubMed:19589127}. <button type='primary' size='sm' modal='Pfam_Domains'>Pfam Domains</button> <button type='primary' size='sm' modal='GO_terms'>GO Terms</button> <modal id='Pfam_Domains' size='lg' title='Pfam Domains'> |LRRNT| |LRR 4| </modal> <modal id='GO_terms' size='lg' title='GO Terms'> |negative regulation of tooth mineralization| |negative regulation of odontogenesis| |regulation of tooth mineralization| |extracellular matrix structural constituent conferring compression resistance| |regulation of odontogenesis| |negative regulation of biomineral tissue development| |negative regulation of biomineralization| |negative regulation of animal organ morphogenesis| |bone mineralization| |collagen binding| |negative regulation of transforming growth factor beta receptor signaling pathway| |negative regulation of cellular response to transforming growth factor beta stimulus| |biomineralization| |biomineral tissue development| |regulation of biomineralization| |regulation of biomineral tissue development| |regulation of transforming growth factor beta receptor signaling pathway| |negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway| |regulation of cellular response to transforming growth factor beta stimulus| |negative regulation of cellular response to growth factor stimulus| |extracellular matrix| |regulation of transmembrane receptor protein serine/threonine kinase signaling pathway| |regulation of animal organ morphogenesis| |ossification| |regulation of cellular response to growth factor stimulus| |collagen-containing extracellular matrix| |calcium ion binding| |negative regulation of developmental process| |regulation of anatomical structure morphogenesis| |negative regulation of multicellular organismal process| |negative regulation of signal transduction| |negative regulation of cell communication| |negative regulation of signaling| |negative regulation of response to stimulus| |tissue development| </modal> \\ === CRISPR Data === <button type='primary' size='small' modal='Compound_Hit'>Compound Hit</button> <button type='default' size='small' modal='Most_Correlated_Genes'>Most Correlated Genes in Chemogenomics</button> <button type='primary' size='small' modal='Essential_Avana'>Tissues where Essential in the Avana Dataset (DepMap 20Q1)</button> <modal id='Compound_Hit' size='lg' title='Compound Hit'> ^Screen^Score^ |[[:results:exp352|Dexamethasone 0.006 to 0.015μM on day4 R07 exp352]]|-1.99| |[[:results:exp249|Vinorelbine 0.001μM R05 exp249]]|1.74| |[[:results:exp108|Vinblastine 0.2μM R03 exp108]]|1.88| </modal> <modal id='Most_Correlated_Genes' size='lg' title='Most Correlated Genes in Chemogenomics'> No correlation found to any other genes in chemogenomics. </modal> <modal id='Essential_Avana' size='lg' title='Tissues where Essential in the Avana Dataset (DepMap 20Q1)'> Global Fraction of Cell Lines Where Essential: N/A ^Tissue^Fraction Of Cell Lines Where Essential^ </modal> == Essentiality in NALM6 == * **<color #00a2e8>Essentiality Rank</color>**: 18538 * **<color #00a2e8>Expression level (log2 read counts)</color>**: -0.46 <button type='primary' size='small' modal='Dist_expr'>Expression Distribution</button> <modal id='Dist_expr' size='lg' title='ASPN Expression in NALM6 Cells: -0.46'> {{:chemogenomics:nalm6 dist.png?nolink |}} </modal> Last modified: 2026/01/07 22:36by 127.0.0.1
