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.

2 GO annotations of cellular component

Name Definition
nuclear origin of replication recognition complex A multisubunit complex that is located at the replication origins of a chromosome in the nucleus.
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.

5 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
ATP hydrolysis activity Catalysis of the reaction
chromatin binding Binding to chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
DNA binding Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
metal ion binding Binding to a metal ion.

3 GO annotations of biological process

Name Definition
DNA amplification The process in which the number of copies of a gene is increased in certain cells as extra copies of DNA are made in response to certain signals of cell development or of stress from the environment.
DNA replication initiation The process in which DNA-dependent DNA replication is started; it begins when specific sequences, known as origins of replication, are recognized and bound by the origin recognition complex, followed by DNA unwinding.
mitotic DNA replication checkpoint signaling A signal transduction process that contributes to a mitotic DNA replication checkpoint.
