molecular function |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0030674 | | protein binding, bridging | | The binding activity of a molecule that brings together two or more protein molecules, or a protein and another macromolecule or complex, through a selective, non-covalent, often stoichiometric interaction, permitting those molecules to function in a coordinated way. |
| GO:0005198 | | structural molecule activity | | The action of a molecule that contributes to the structural integrity of a complex or its assembly within or outside a cell. |
biological process |
| GO:0018153 | | isopeptide cross-linking via N6-(L-isoglutamyl)-L-lysine | | The formation of an isopeptide cross-link between peptidyl-lysine and peptidyl-glutamine to produce N6-(L-isoglutamyl)-L-lysine. |
| GO:0031424 | | keratinization | | The process in which the cytoplasm of the outermost cells of the vertebrate epidermis is replaced by keratin. Keratinization occurs in the stratum corneum, feathers, hair, claws, nails, hooves, and horns. |
| GO:0030216 | | keratinocyte differentiation | | The process in which a relatively unspecialized cell acquires specialized features of a keratinocyte. |
| GO:0018149 | | peptide cross-linking | | The formation of a covalent cross-link between or within protein chains. |
| GO:0010224 | | response to UV-B | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a UV-B radiation stimulus. UV-B radiation (UV-B light) spans the wavelengths 280 to 315 nm. |
cellular component |
| GO:0001533 | | cornified envelope | | A type of plasma membrane that has been modified through addition of distinct intracellular and extracellular components, including ceramide, found in cornifying epithelial cells (corneocytes). |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |
