MeSH

A sequence of responses that occur when an organism is exposed to excessive heat. In humans, an increase in skin temperature triggers muscle relaxation, sweating, and vasodilation.

Year introduced: 1996

A subfamily of small heat-shock proteins that function as molecular chaperones that aid in refolding of non-native proteins. They play a protective role that increases cellular survival during times of stress.

Year introduced: 2009(1989)

A group of eukaryotic high-molecular mass heat-shock proteins that represent a subfamily of HSP70 HEAT-SHOCK PROTEINS. Hsp110 proteins prevent protein aggregation and can maintain denatured proteins in folding-competent states.

Year introduced: 2006(1995)

A family of heat-shock proteins that contain a 70 amino-acid consensus sequence known as the J domain. The J domain of HSP40 heat shock proteins interacts with HSP70 HEAT-SHOCK PROTEINS. HSP40 heat-shock proteins play a role in regulating the ADENOSINE TRIPHOSPHATASES activity of HSP70 heat-shock proteins.

Year introduced: 2006(1986)

A family of low molecular weight heat-shock proteins that can serve as MOLECULAR CHAPERONES.

Year introduced: 2006

A subfamily of small heat-shock proteins that are closely related to ALPHA B-CRYSTALLIN. Hsp20 heat-shock proteins can undergo PHOSPHORYLATION by CYCLIC GMP-DEPENDENT PROTEIN KINASES.

Year introduced: 2006(1997)

Stress-inducible members of the heat-shock proteins 70 family. HSP72 heat shock proteins function with other MOLECULAR CHAPERONES to mediate PROTEIN FOLDING and to stabilize pre-existent proteins against aggregation.

Year introduced: 2006(1994)

A constitutively expressed subfamily of the HSP70 heat-shock proteins. They preferentially bind and release hydrophobic peptides by an ATP-dependent process and are involved in post-translational PROTEIN TRANSLOCATION.

Year introduced: 2006(2001)

A class of MOLECULAR CHAPERONES found in both prokaryotes and in several compartments of eukaryotic cells. These proteins can interact with polypeptides during a variety of assembly processes in such a way as to prevent the formation of nonfunctional structures.

Year introduced: 2006(1990)

Basic glycoprotein members of the SERPIN SUPERFAMILY that function as COLLAGEN-specific MOLECULAR CHAPERONES in the ENDOPLASMIC RETICULUM.

Year introduced: 2006(1993)

A subfamily of small heat-shock proteins found in a wide variety of organisms.

Year introduced: 2006(1993)

A class of MOLECULAR CHAPERONES whose members act in the mechanism of SIGNAL TRANSDUCTION by STEROID RECEPTORS.

Year introduced: 2006(1994)

Proteins which are synthesized in eukaryotic organisms and bacteria in response to hyperthermia and other environmental stresses. They increase thermal tolerance and perform functions essential to cell survival under these conditions.

Year introduced: 1984

Heat and cold stress-inducible, transcription factors that bind to inverted 5'-NGAAN-3' pentamer DNA sequences and are regulated by POLY-ADP-RIBOSYLATION. They play essential roles as transcriptional activators of the HEAT-SHOCK RESPONSE by inducing expression of large classes of MOLECULAR CHAPERONES and heat-shock proteins. They also function in DNA REPAIR; transcriptional reactivation of latent HIV-1; and pre-mRNA processing and nuclear export of HSP70 HEAT-SHOCK PROTEINS during heat stress.

Year introduced: 2018 (1992)

A group I chaperonin protein that forms a lid-like structure which encloses the non-polar cavity of the chaperonin complex. The protein was originally studied in BACTERIA where it is commonly referred to as GroES protein.

Year introduced: 1995(1989)

A group I chaperonin protein that forms the barrel-like structure of the chaperonin complex. It is an oligomeric protein with a distinctive structure of fourteen subunits, arranged in two rings of seven subunits each. The protein was originally studied in BACTERIA where it is commonly referred to as GroEL protein.

Year introduced: 1995(1989)

a 59 KD FK506 binding protein; associates with HSP90; has peptidyl-prolyl cis/trans isomerase activity

Date introduced: July 31, 2000

RefSeq NM_002154

Date introduced: November 3, 1999

a 23 kDa heat-shock protein; amino acid sequence in first source

Date introduced: June 9, 1997

shares sequence identity with members of the eukaryotic heat-shock proteins; functions as a molecular chaperone; from Leishmania tropica; hsp70.1 & hsp 70.3 encode identical proteins which protect cells & facilitate their recovery from stress-induced damage; amino acid sequence given in first source; RefSeq NM_010478.2 (mouse)
