Description
EC Number 2.7.11.1 Protein-serine/threonine kinases
Subcellular Localization
  • Nucleus
  • Chromosome
  • Chromosome, centromere
  • Chromosome, centromere, kinetochore
  • Cytoplasm, cytoskeleton, spindle
  • Midbody
  • Localizes on chromosome arms and inner centromeres from prophase through metaphase and then transferring to the spindle midzone and midbody from anaphase through cytokinesis
  • Colocalized with gamma tubulin in the midbody
  • Proper localization of the active, Thr-232-phosphorylated form during metaphase may be dependent upon interaction with SPDYC
  • Colocalized with SIRT2 during cytokinesis with the midbody
  • Localization (and probably targeting of the CPC) to the inner centromere occurs predominantly in regions with overlapping mitosis-specific histone phosphorylations H3pT3 and H2ApT12

8 GO annotations of cellular component

Name Definition
chromosome passenger complex A eukaryotically conserved protein complex that localizes to kinetochores in early mitosis, the spindle mid-zone in anaphase B and to the telophase midbody. It has been proposed that the passenger complex coordinates various events based on its location to different structures during the course of mitosis. Complex members include the BIR-domain-containing protein Survivin, Aurora kinase, INCENP and Borealin.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
kinetochore A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.
midbody A thin cytoplasmic bridge formed between daughter cells at the end of cytokinesis. The midbody forms where the contractile ring constricts, and may persist for some time before finally breaking to complete cytokinesis.
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 microtubule Any microtubule that is part of a mitotic or meiotic spindle; anchored at one spindle pole.
spindle midzone The area in the center of the spindle where the spindle microtubules from opposite poles overlap.
spindle pole centrosome A centrosome from which one pole of a mitotic or meiotic spindle is organized.

5 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
histone kinase activity (H3-S28 specific) Catalysis of the transfer of a phosphate group to the serine-28 residue of histone H3.
histone serine kinase activity Catalysis of the transfer of a phosphate group to a serine residue of a histone.
protein serine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate.
protein serine/threonine kinase activity Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.

16 GO annotations of biological process

Name Definition
abscission The controlled shedding of a body part.
cellular response to UV 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 an ultraviolet radiation (UV light) stimulus. Ultraviolet radiation is electromagnetic radiation with a wavelength in the range of 10 to 380 nanometers.
cleavage furrow formation Generation of the cleavage furrow, a shallow groove in the cell surface near the old metaphase plate that marks the site of cytokinesis. This process includes the recruitment and localized activation of signals such as RhoA at the site of the future furrow to ensure that furrowing initiates at the correct site in the cell.
mitotic cytokinesis checkpoint signaling A signaling process that contributes to a mitotic cell cycle checkpoint that detects a defect in cytokinesis and prevents further rounds of nuclear division until cytokinesis is completed.
mitotic spindle assembly checkpoint signaling A signal transduction process that contributes to a mitotic cell cycle spindle assembly checkpoint, that delays the metaphase/anaphase transition of a mitotic nuclear division until the spindle is correctly assembled and chromosomes are attached to the spindle.
mitotic spindle midzone assembly The cell cycle process in which the aggregation, arrangement and bonding together of a set of components forms the spindle midzone.
mitotic spindle organization A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle.
negative regulation of B cell apoptotic process Any process that stops, prevents, or reduces the frequency, rate, or extent of B cell apoptotic process.
negative regulation of cytokinesis Any process that stops, prevents, or reduces the frequency, rate or extent of the division of the cytoplasm of a cell, and its separation into two daughter cells.
negative regulation of transcription by RNA polymerase II Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II.
positive regulation of cytokinesis Any process that activates or increases the frequency, rate or extent of the division of the cytoplasm of a cell, and its separation into two daughter cells.
positive regulation of mitotic sister chromatid segregation Any process that starts or increases the frequency, rate or extent of sister chromatid segregation during mitosis.
post-translational protein modification The process of covalently altering one or more amino acids in a protein after the protein has been completely translated and released from the ribosome.
protein localization to kinetochore Any process in which a protein is transported to, or maintained at, the kinetochore.
protein phosphorylation The process of introducing a phosphate group on to a protein.
regulation of cytokinesis Any process that modulates the frequency, rate or extent of the division of the cytoplasm of a cell and its separation into two daughter cells.
