Descriptions

Rho kinases (ROCKs) are serine/threonine kinases that are involved in many aspects of cell motility, from smooth-muscle contraction to cell migration and neurite outgrowth. ROCK2 contains an N-terminal kinase domain, Rho-binding domain (RBD), and PH domain. RBD and PH domains interact with the catalytic kinase domain for autoinhibition. Rho binding to RBD relieves the autoinhibition.

9 GO annotations of cellular component

Name Definition
centrosome A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
cytoplasmic ribonucleoprotein granule A ribonucleoprotein granule located in the cytoplasm.
cytoskeleton A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles.
glutamatergic synapse A synapse that uses glutamate as a neurotransmitter.
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.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
Schaffer collateral - CA1 synapse A synapse between the Schaffer collateral axon of a CA3 pyramidal cell and a CA1 pyramidal cell.
spindle pole centrosome A centrosome from which one pole of a mitotic or meiotic spindle is organized.

dendrite morphogenesis The process in which the anatomical structures of a dendrite are generated and organized.
embryonic morphogenesis The process in which anatomical structures are generated and organized during the embryonic phase. The embryonic phase begins with zygote formation. The end of the embryonic phase is organism-specific. For example, it would be at birth for mammals, larval hatching for insects and seed dormancy in plants.
epithelial to mesenchymal transition A transition where an epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell.
extrinsic apoptotic signaling pathway via death domain receptors The series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with a ligand binding to a death domain receptor on the cell surface, and ends when the execution phase of apoptosis is triggered.
I-kappaB kinase/NF-kappaB signaling The process in which a signal is passed on to downstream components within the cell through the I-kappaB-kinase (IKK)-dependent activation of NF-kappaB. The cascade begins with activation of a trimeric IKK complex (consisting of catalytic kinase subunits IKKalpha and/or IKKbeta, and the regulatory scaffold protein NEMO) and ends with the regulation of transcription of target genes by NF-kappaB. In a resting state, NF-kappaB dimers are bound to I-kappaB proteins, sequestering NF-kappaB in the cytoplasm. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing the NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription.
