molecular function |
| GO:0005509 | | calcium ion binding | | Interacting selectively and non-covalently with calcium ions (Ca2+). |
| GO:0008047 | | enzyme activator activity | | Binds to and increases the activity of an enzyme. |
| GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0004222 | | metalloendopeptidase activity | | Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions. |
| GO:0008237 | | metallopeptidase activity | | Catalysis of the hydrolysis of peptide bonds by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions. |
| GO:0008233 | | peptidase activity | | Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid. |
| GO:0008270 | | zinc ion binding | | Interacting selectively and non-covalently with zinc (Zn) ions. |
biological process |
| GO:0060348 | | bone development | | The process whose specific outcome is the progression of bone over time, from its formation to the mature structure. Bone is the hard skeletal connective tissue consisting of both mineral and cellular components. |
| GO:0035988 | | chondrocyte proliferation | | The multiplication or reproduction of chondrocytes by cell division, resulting in the expansion of their population. A chondrocyte is a polymorphic cell that forms cartilage. |
| GO:0030574 | | collagen catabolic process | | The proteolytic chemical reactions and pathways resulting in the breakdown of collagen in the extracellular matrix, usually carried out by proteases secreted by nearby cells. |
| GO:0097094 | | craniofacial suture morphogenesis | | The process in which any suture between cranial and/or facial bones is generated and organized. |
| GO:0048701 | | embryonic cranial skeleton morphogenesis | | The process in which the anatomical structures of the cranial skeleton are generated and organized during the embryonic phase. |
| GO:0001958 | | endochondral ossification | | Replacement ossification wherein bone tissue replaces cartilage. |
| GO:0022617 | | extracellular matrix disassembly | | A process that results in the breakdown of the extracellular matrix. |
| GO:0001503 | | ossification | | The formation of bone or of a bony substance, or the conversion of fibrous tissue or of cartilage into bone or a bony substance. |
| GO:0043085 | | positive regulation of catalytic activity | | Any process that activates or increases the activity of an enzyme. |
| GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
cellular component |
| GO:0005796 | | Golgi lumen | | The volume enclosed by the membranes of any cisterna or subcompartment of the Golgi apparatus, including the cis- and trans-Golgi networks. |
| GO:0009986 | | cell surface | | The external part of the cell wall and/or plasma membrane. |
| GO:0031012 | | extracellular matrix | | A structure lying external to one or more cells, which provides structural support for cells or tissues. |
| GO:0005576 | | extracellular region | | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. |
| GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| GO:0005887 | | integral component of plasma membrane | | The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| GO:0005578 | | proteinaceous extracellular matrix | | A layer consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that forms a sheet underlying or overlying cells such as endothelial and epithelial cells. The proteins are secreted by cells in the vicinity. An example of this component is found in Mus musculus. |
