Descriptions
Protein phosphatase 5 (PP5) is a serine/threonine protein phosphatase comprising a regulatory tetratricopeptide repeat (TPR) domain N-terminal to its phosphatase domain. PP5 functions in signaling pathways that control cellular responses to stress, glucocorticoids and DNA damage. Its phosphatase activity is suppressed by an autoinhibited conformation maintained by the TPR domain and a C-terminal region. The TPR domain engages with the catalytic channel of the phosphate domain, restricting access to the catalytic site. This autoinhibited conformation of PP5 is stabilized by the C-terminal αJ helix. In a study with rat PPP5C (P53042), the protein also contains a C-terminal regulatory region that may interact with the TPR domain.

11 GO annotations of cellular component
Name | Definition |
---|---|
cell periphery | The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures. |
chaperone complex | A protein complex required for the non-covalent folding or unfolding, maturation, stabilization or assembly or disassembly of macromolecular structures. Usually active during or immediately after completion of translation. Many chaperone complexes contain heat shock proteins. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
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. |
perikaryon | The portion of the cell soma (neuronal cell body) that excludes the nucleus. |
plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
protein-containing complex | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. |
proximal dendrite | The dendrite of the dendritic tree that is closest to the neuronal cell body (the soma). |
