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.
This gene encodes a cartilage extracellular protein that is member of the small leucine-rich proteoglycan family. 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]

| 26446945 | To test the associations of ASPN variations with risk of subsequent oncologic outcomes. |
| 26016288 | this is the first case-control study in Mexican women that suggests that menopause and the D-repeat polymorphism in the ASPN gene are associated with knee OA |
| 25673058 | Collectively, our findings indicate that ASPN is upregulated and plays an oncogenic role in gastric cancer progression and metastasis by influencing the EGFR signaling pathway. |
| 25371314 | Osteomodulin, osteoglycin, and asporin appear to be distinctly regulated in osteoarthritis labrum compared to OA cartilage. |
| 25030405 | Our results showed that ASPN rs13301537 T to C change and variant C genotype may contribute to knee OA risk in a Chinese Han population. |
| 24453179 | D14-PLAP-1 suppressed BMP-2 signal transduction more efficiently than D13-PLAP-1; stronger affinity of D14-PLAP-1 protein to BMP-2 compared with D13-PLAP-1 protein. D repeat polymorphism of PLAP-1/asporin has influence on functions of PDL cells. |
| 24441039 | Asporin may represent a new therapeutic target molecule for the development of drugs aimed at manipulating the cancer microenvironment. |
| 24306268 | This meta-analysis shows that the ASPN D14, D13, and D15 alleles are not associated with the development of osteoarthritis in Europeans and Asians. [Meta-Analysis] |
| 24078942 | Our data suggest that the D15 asporin allele could be considered a knee osteoarthritis risk allele significant only for women in the Iranian population. |
| 24003854 | The asporin-encoding gene is a promising candidate as a susceptibility gene for osteoarthritis and degenerative disc disease. [Review] |
