Disease relevance of Hspd1

 

High impact information on Hspd1

  • The chaperonin GroEL is able to mediate protein folding in its central cavity [6].
  • Folding of the major cytoskeletal components in the cytosol of mammalian cells is mediated by interactions with t-complex polypeptide-1 (TCP1) molecular chaperones, a situation analogous to the chaperonin 60-aided folding of polypeptides in bacteria, chloroplasts and mitochondria [7].
  • Here we report for the first time that a protein, identified by a monoclonal antibody to be the Mt heat shock protein (Baird, P.N., L.M. Hall, and A.R.M. Coates. 1989. J. Gen. Microbiol. 135:931-939) chaperonin (cpn) 10, is responsible for the osteolytic activity of this bacterium [1].
  • Here we find that upon ATP binding, mimicked by the non-hydrolysable analog AMP-PNP (5'-adenylyl-imido-diphosphate), to both CCT-alpha-actin and CCT- beta-tubulin complexes, the chaperonin component undergoes concerted movements of the apical domains, resulting in the cavity being closed off by the helical protrusions of the eight apical domains [8].
  • Structure of a trimeric domain of the MHC class II-associated chaperonin and targeting protein Ii [9].

Associations of Hspd1 with chemical compounds

 

Physical interactions of Hspd1

  • Analysis of the nascent translation products for folding intermediates has identified a major intermediate that contains all three myosin subunits in a complex with the eukaryotic cytosolic chaperonin [23].
  • The receptor-associated protein, RAP, is a chaperonin-like molecule that binds to two members of the low density lipoprotein receptor (LDLR) superfamily-megalin (gp330) and the LDL receptor-related protein (LRP) [24].
 

Other interactions of Hspd1

 

Analytical, diagnostic and therapeutic context of Hspd1

  • Sequence analysis of four candidate genes in this interval revealed a 1349G>A mutation in the chaperonin (delta) subunit 4 (Cct4) gene associated with the mf mutant [27].
  • In analogy to GroEL, changes in shape of the cytosolic chaperonin have been detected in the presence of MgATP using electron microscopy but, in contrast to the nucleotide-induced conformational changes in GroEL, no details are available about the specific nature of these changes [28].
  • The three-dimensional reconstruction of apo-CCT-alpha-actin by cryoelectron microscopy shows that actin binds either the CCTbeta-CCTdelta or the CCTepsilon-CCTdelta subunit pairs of the chaperonin in an open and apparently quasi-native conformation [29].
  • Investigations with the latter confirmed that chaperonin 10 is the moiety in pregnancy serum which initiates response in the EPF bioassay [30].
  • Molecular cloning and characterization of a group II chaperonin delta-subunit from soybean [31].
