Descriptions
HSPA8 (or hsc70) is a heat shock cognate protein involved in many cellular processes. During recovery from stress, HSPA8, initially accumulating in the nucleoplasm for folding/refolding of proteins, transiently concentrates in nucleoli for nucleolar morphology and function restoration. The inhibitory region is positioned at one of the three domains of HSPA8 protein, which is the N-terminal ATPase domain, specifically in residues 263-287 of domain IIB. Under normal growth conditions, the constitutive nucleolar targeting function that is provided by residues 225-262 is diminished by the autoinhibitory element located in residues 263-287. When cells recover from stress, the autoinhibitory element is inactivated, and the constitutive nucleolar targeting function restores.

| Name | Definition |
|---|---|
| CatSper complex | A sperm-specific voltage-gated calcium channel that controls the intracellular calcium ion concentration and, thereby, the swimming behavior of sperm. Consists of a heteromeric tetramer surrounding a calcium ion- selective pore. May also contain additional auxiliary subunits. |
| cell surface | The external part of the cell wall and/or plasma membrane. |
| 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. |
| male germ cell nucleus | The nucleus of a male germ cell, a reproductive cell in males. |
| 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. |
| 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. |
| synaptonemal complex | A proteinaceous scaffold found between homologous chromosomes during meiosis. It consists of 2 lateral elements and a central element, all running parallel to each other. Transverse filaments connect the lateral elements to the central element. |
