Descriptions

RSK1 plays an important role in many cellular processes. RSK1 is expressed ubiquitously in almost all human tissues, predominantly in kidney, lung and pancreas.The crystal structure of human RSK1 C-terminal kinase domain (CTKD) has been reported. The structure indicates that the autoinhibition of the CTKD is caused by an α-helix occupying the substrate-binding groove.The structure shows autoinhibition of RSK1 CTKD by its αL helix, suggesting that ERK1/2 may activate RSK1 by phosphorylating RSK1 followed by the displacement of αL from its inhibitory position. A similar regulatory mechanism has been observed previously in MAPKAP kinase 2 and murine RSK2 CTKD. The atomic structure of human RSK1 CTKD is of great interest in order to understand the mechanism of RSK activation and for structure-based anticancer-drug development.

5 GO annotations of cellular component

Name Definition
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
meiotic spindle A spindle that forms as part of meiosis. Several proteins, such as budding yeast Spo21p, fission yeast Spo2 and Spo13, and C. elegans mei-1, localize specifically to the meiotic spindle and are absent from the mitotic spindle.
nucleoplasm That part of the nuclear content other than the chromosomes or the nucleolus.
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
spindle The array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during mitosis or meiosis and serves to move the duplicated chromosomes apart.

7 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
magnesium ion binding Binding to a magnesium (Mg) ion.
protein kinase activity Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction
protein serine kinase activity Catalysis of the reactions
protein serine/threonine kinase activity Catalysis of the reactions
protein serine/threonine/tyrosine kinase activity Catalysis of the reactions

14 GO annotations of biological process

Name Definition
brain renin-angiotensin system The process in which an angiotensin-mediated signaling system present in the brain regulates the force with which blood passes through the circulatory system.
cardiac muscle cell apoptotic process A form of programmed cell death induced by external or internal signals that trigger the activity of proteolytic caspases, whose actions dismantle a cardiac muscle cell and result in its death. Cardiac muscle cells are striated muscle cells that are responsible for heart contraction.
cellular response to carbohydrate stimulus Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a carbohydrate stimulus.
heart contraction The multicellular organismal process in which the heart decreases in volume in a characteristic way to propel blood through the body.
heart development The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
intracellular signal transduction The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.
negative regulation of cell cycle Any process that stops, prevents or reduces the rate or extent of progression through the cell cycle.
negative regulation of cell population proliferation Any process that stops, prevents or reduces the rate or extent of cell proliferation.
negative regulation of meiotic nuclear division Any process that stops, prevents, or reduces the frequency, rate or extent of meiosis.
oocyte maturation A developmental process, independent of morphogenetic (shape) change, that is required for an oocyte to attain its fully functional state. Oocyte maturation commences after reinitiation of meiosis commonly starting with germinal vesicle breakdown, and continues up to the second meiotic arrest prior to fertilization.
phosphorylation The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
positive regulation of apoptotic process Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.
positive regulation of gene expression Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
regulation of protein processing Any process that modulates the frequency, rate or extent of protein processing, a protein maturation process achieved by the cleavage of a peptide bond or bonds within a protein.
