| Protein names | Recommended name: Collagen alpha-1(IX) chain | ||
| Gene names |
| ||
| Organism | Mus musculus (Mouse) [Reference proteome] | ||
| Taxonomic identifier | 10090 [NCBI] | ||
| Taxonomic lineage | Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Glires › Rodentia › Sciurognathi › Muroidea › Muridae › Murinae › Mus › Mus![]() |
Protein attributes
| Sequence length | 921 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Structural component of hyaline cartilage and vitreous of the eye. |
| Subunit structure | Heterotrimer of an alpha 1(IX), an alpha 2(IX) and an alpha 3(IX) chain. |
| Subcellular location | Secreted › extracellular space › extracellular matrix By similarity. |
| Domain | Each subunit is composed of three triple-helical domains interspersed with non-collagenous domains. The globular domain at the N-terminus of type IX collagen molecules represents the NC4 domain which may participate in electrostatic interactions with polyanionic glycosaminoglycans in cartilage. |
| Post-translational modification | Covalently linked to the telopeptides of type II collagen by lysine-derived cross-links. Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains. |
| Sequence similarities | Belongs to the fibril-associated collagens with interrupted helices (FACIT) family. Contains 9 collagen-like domains. Contains 1 laminin G-like domain. |
