GO Term
Description: The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
GO Term
Description: Combining with a chemokine, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity. Chemokines are a family of small chemotactic cytokines; their name is derived from their ability to induce directed chemotaxis in nearby responsive cells. All chemokines possess a number of conserved cysteine residues involved in intramolecular disulfide bond formation. Some chemokines are considered pro-inflammatory and can be induced during an immune response to recruit cells of the immune system to a site of infection, while others are considered homeostatic and are involved in controlling the migration of cells during normal processes of tissue maintenance or development. Chemokines are found in all vertebrates, some viruses and some bacteria.
UniProt Feature
Begin: 497
Description: In osz2; semi-dominant mutation with impaired proteolytic processing, and leading to an increased sensitivity to zinc Zn(2+) characterized by Zn-triggered reduced root elongation due to a defect in cell elongation, but an increase number of root hairs; this phenotype is suppressed by calcium Ca(2+) treatment. No obvious impact on pectin methylesterification.

GO Term
Description: Any process that activates or increases the frequency, rate or extent of directed movement of RNA from the nucleus into the cytoplasm.
GO Term
Description: A cellular structure that is the site of a developing centriole, which will become a microtubule organizing center. During the canonical pathway of centriole duplication that occurs during the cell division cycle, procentrioles grow at the proximal ends of both mother and daughter centrioles. In the newly divided cells, the original mother and daughter centrioles become mother centrioles while the procentrioles become the new daughter centrioles. Procentrioles can also arise from de novo pathways that occur in multiciliated cells. In ciliated epithelial cells, numerous procentrioles arise form electron dense material referred to as fibrous granules and deuterosomes. The pathway of procentriole formation in multiciliated protists appears to be similar to that in mammalian multiciliated epithelium. In sperm of primitive land plants, multiple procentrioles are formed from a blepharoplast giving rise to multicilated sperm cells.

Description: In BASL_123456D; phosphomimetic, increased interaction with YDA and promoted polarization; when associated with D-72, D-145, D-168, D-235 and D-246. In BASL_14D; reduced mobility leading to severely retarded recovery at the cell cortex and prolonged accumulation even in mature pavement cells, and impaired stomatal production due to suppressed SLGC division potential; when associated with D-72.

UniProt Feature
Begin: 31
Description: In crl-2; impeded plastid division leading to enlarged chloroplasts in mesophyll cells and abnormal plastid homeostasis, thus resulting in preconditioning plants by activating the expression of stress genes, enhancing pathogen resistance (e.g. Pseudomonas syringae DC3000) and attenuating the capacity to respond to plastid signals. Spontaneous light intensity-dependent cell death formation associated with O(2) production.

GO Term
Description: An immune response mediated by lymphocytes expressing specific receptors for antigen produced through a somatic diversification process that includes somatic recombination of germline gene segments encoding immunoglobulin superfamily domains. Recombined receptors for antigen encoded by immunoglobulin superfamily domains include T cell receptors and immunoglobulins (antibodies) produced by B cells. The first encounter with antigen elicits a primary immune response that is slow and not of great magnitude. T and B cells selected by antigen become activated and undergo clonal expansion. A fraction of antigen-reactive T and B cells become memory cells, whereas others differentiate into effector cells. The memory cells generated during the primary response enable a much faster and stronger secondary immune response upon subsequent exposures to the same antigen (immunological memory). An example of this is the adaptive immune response found in Mus musculus.
UniProt Feature
Begin: 111
Description: In spch-5; normal growth, but extremely low number of sometimes clustered stomata in leaves and stomata free hypocotyls due to decreased ability to initiate and amplify lineages, defects in asymmetric cell fate allocation, and misorientation of asymmetric division planes. These phenotypes are partly rescued by brassinosteroids (BRs) by rescuing the expression of a set of target genes.

GO Term
Description: A small amount of cytoplasm surrounded by a cell membrane that is generally retained in spermatozoa after spermiogenesis, when the majority of the cytoplasm is phagocytosed by Sertoli cells to produce what are called residual bodies. Initially, the droplet is located at the neck just behind the head of an elongated spermatid. During epididymal transit, the cytoplasmic droplet migrates caudally to the annulus at the end of the midpiece; the exact position and time varies by species. The cytoplasmic droplet consists of lipids, lipoproteins, RNAs, a variety of hydrolytic enzymes, receptors, ion channels, and Golgi-derived vesicles. The droplet may be involved in regulatory volume loss (RVD) at ejaculation, and in most species, though not in humans, the cytoplasmic droplet is lost at ejaculation. Note that the cytoplasmic droplet is distinct from 'excessive residual cytoplasm' that sometimes remains in epididymal spermatozoa, particularly when spermiogenesis has been disrupted.
