| GO:0005575 | cellular_component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
| GO:0110165 | cellular anatomical structure | A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
| GO:0043226 | organelle | Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. |
| GO:0120025 | plasma membrane bounded cell projection | A prolongation or process extending from a cell and that is bounded by plasma membrane, e.g. a cilium, lamellipodium, or axon. |
| GO:0042995 | cell projection | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| GO:0043005 | neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| GO:0032421 | stereocilium bundle | A bundle of cross-linked stereocilia, arranged around a kinocilium on the apical surface of a sensory hair cell (e.g. a neuromast, auditory or vestibular hair cell). Stereocilium bundles act as mechanosensory organelles by responding to fluid motion or fluid pressure changes. |
| GO:0098862 | cluster of actin-based cell projections | A cell part consisting of multiple, closely packed actin-based cell projections. |
| GO:0098858 | actin-based cell projection | A cell projection supported by an assembly of actin filaments, and which lacks microtubules. |
| GO:0032420 | stereocilium | An actin-based protrusion from the apical surface of auditory and vestibular hair cells and of neuromast cells. These protrusions are supported by a bundle of cross-linked actin filaments (an actin cable), oriented such that the plus (barbed) ends are at the tip of the protrusion, capped by a tip complex which bridges to the plasma. Bundles of stereocilia act as mechanosensory organelles. |
| GO:0032426 | stereocilium tip | A distinct compartment at the tip of a stereocilium, distal to the site of attachment to the apical cell surface. It consists of a dense matrix bridging the barbed ends of the stereocilium actin filaments with the overlying plasma membrane, is dynamic compared to the shaft, and is required for stereocilium elongation. |
