Members of this protein family, rich in coiled coil regions, are molecular chaperones in the class of the prefoldin (GimC) alpha subunit. Prefoldin is a hexamer of two alpha and four beta subunits. This protein appears universal in the archaea but is restricted to Aquifex aeolicus among bacteria so far. Eukaryotes have several related proteins; only prefoldin subunit 5, which appeared the most similar to archaeal prefoldin alpha, is included in this model. This model finds a set of small proteins from the Archaea and from Aquifex aeolicus that may represent two orthologous groups. The proteins are predicted to be mostly coiled coil [Protein fate, Protein folding and stabilization]. Length = 126

This family comprises of several prefoldin subunits. The biogenesis of the cytoskeletal proteins actin and tubulin involves interaction of nascent chains of each of the two proteins with the oligomeric protein prefoldin (PFD) and their subsequent transfer to the cytosolic chaperonin CCT (chaperonin containing TCP-1). Electron microscopy shows that eukaryotic PFD, which has a similar structure to its archaeal counterpart, interacts with unfolded actin along the tips of its projecting arms. In its PFD-bound state, actin seems to acquire a conformation similar to that adopted when it is bound to CCT. Length = 120

>PF02996 Prefoldin: Prefoldin subunit; InterPro: IPR004127 This entry comprises of several prefoldin subunits
Prefoldin (PFD) is a chaperone that interacts exclusively with type II chaperonins, hetero-oligomers lacking an obligate co-chaperonin that are found only in eukaryotes (chaperonin-containing T-complex polypeptide-1 (CCT)) and archaea. Eukaryotic PFD is a multi-subunit complex containing six polypeptides in the molecular mass range of 14-23 kDa. In archaea, on the other hand, PFD is composed of two types of subunits, two alpha and four beta. The six subunits associate to form two back-to-back up-and-down eight-stranded barrels, from which hang six coiled coils. Each subunit contributes one (beta subunits) or two (alpha subunits) beta hairpin turns to the barrels. The coiled coils are formed by the N and C termini of an individual subunit. Overall, this unique arrangement resembles a jellyfish. The eukaryotic PFD hexamer is composed of six different subunits; however, these can be grouped into two alpha-like (PFD3 and -5) and four beta-like (PFD1, -2, -4, and -6) subunits based on amino acid sequence similarity with their archaeal counterparts. Eukaryotic PFD has a six-legged structure similar to that seen in the archaeal homologue [, ]. This family contains the archaeal alpha subunit, eukaryotic prefoldin subunits 3 and 5 and the UXT (ubiquitously expressed transcript) family. Eukaryotic PFD has been shown to bind both actin and tubulin co-translationally. The chaperone then delivers the target protein to CCT, interacting with the chaperonin through the tips of the coiled coils. No authentic target proteins of any archaeal PFD have been identified, to date.; GO: 0051082 unfolded protein binding, 0006457 protein folding, 0016272 prefoldin complex; PDB: 1FXK_C 2ZDI_C.

>COG1730 GIM5 Predicted prefoldin, molecular chaperone implicated in de novo protein folding [Posttranslational modification, protein turnover, chaperones]
This model finds a set of small proteins from the Archaea and from Aquifex aeolicus that may represent two orthologous groups. The proteins are predicted to be mostly coiled coil, and may hit large numbers of proteins that contain coiled coil regions.
Chaperonins are cytosolic, ATP-dependent molecular chaperones, with a conserved toroidal architecture, that assist in the folding of nascent and/or denatured polypeptide chains. The group I chaperonin system consists of GroEL and GroES, and is found (usually) in bacteria and organelles of bacterial origin. The group II chaperonin system, called the thermosome in Archaea and TRiC or CCT in the Eukaryota, is structurally similar but only distantly related. Prefoldin, also called GimC, is a complex in Archaea and Eukaryota, that works with group II chaperonins. Members of this protein family are the archaeal clade of the beta class of prefoldin subunit. Closely related, but outside the scope of this family are the eukaryotic beta-class prefoldin subunits, Gim-1,3,4 and 6. The alpha class prefoldin subunits are more distantly related.
>PF01920 Prefoldin_2: Prefoldin subunit; InterPro: IPR002777 Prefoldin (PFD) is a chaperone that interacts exclusively with type II chaperonins, hetero-oligomers lacking an obligate co-chaperonin that are found only in eukaryotes (chaperonin-containing T-complex polypeptide-1 (CCT)) and archaea
Eukaryotic PFD is a multi-subunit complex containing six polypeptides in the molecular mass range of 14-23 kDa. In archaea, on the other hand, PFD is composed of two types of subunits, two alpha and four beta. The six subunits associate to form two back-to-back up-and-down eight-stranded barrels, from which hang six coiled coils. Each subunit contributes one (beta subunits) or two (alpha subunits) beta hairpin turns to the barrels. The coiled coils are formed by the N and C termini of an individual subunit. Overall, this unique arrangement resembles a jellyfish. The eukaryotic PFD hexamer is composed of six different subunits; however, these can be grouped into two alpha-like (PFD3 and -5) and four beta-like (PFD1, -2, -4, and -6) subunits based on amino acid sequence similarity with their archaeal counterparts. Eukaryotic PFD has a six-legged structure similar to that seen in the archaeal homologue [, ]. This family contains the archaeal beta subunit, eukaryotic prefoldin subunits 1, 2, 4 and 6. Eukaryotic PFD has been shown to bind both actin and tubulin co-translationally. The chaperone then delivers the target protein to CCT, interacting with the chaperonin through the tips of the coiled coils. No authentic target proteins of any archaeal PFD have been identified, to date.; GO: 0051082 unfolded protein binding, 0006457 protein folding, 0016272 prefoldin complex; PDB: 2ZDI_B 3AEI_B 2ZQM_A 1FXK_A.
>cd00632 Prefoldin_beta Prefoldin beta; Prefoldin is a hexameric molecular chaperone complex, composed of two evolutionarily related subunits (alpha and beta), which are found in both eukaryotes and archaea
Prefoldin binds and stabilizes newly synthesized polypeptides allowing them to fold correctly. The hexameric structure consists of a double beta barrel assembly with six protruding coiled-coils. The alpha prefoldin subunits have two beta hairpin structures while the beta prefoldin subunits (this CD) have only one hairpin that is most similar to the second hairpin of the alpha subunit. The prefoldin hexamer consists of two alpha and four beta subunits and is assembled from the beta hairpins of all six subunits. The alpha subunits initially dimerize providing a structural nucleus for the assembly of the beta subunits. In archaea, there is usually only one gene for each subunit while in eukaryotes there two or more paralogous genes encoding each subunit adding heterogeneity to the st

>PF04568 IATP: Mitochondrial ATPase inhibitor, IATP; InterPro: IPR007648 ATP synthase inhibitor prevents the enzyme from switching to ATP hydrolysis during collapse of the electrochemical gradient, for example during oxygen deprivation [] ATP synthase inhibitor forms a one to one complex with the F1 ATPase, possibly by binding at the alpha-beta interface
It is thought to inhibit ATP synthesis by preventing the release of ATP []. The minimum inhibitory region for bovine inhibitor (P01096 from SWISSPROT) is from residues 39 to 72 []. The inhibitor has two oligomeric states, dimer (the active state) and tetramer. At low pH , the inhibitor forms a dimer via antiparallel coiled coil interactions between the C-terminal regions of two monomers. At high pH, the inhibitor forms tetramers and higher oligomers by coiled coil interactions involving the N terminus and inhibitory region, thus preventing the inhibitory activity []. ; GO: 0004857 enzyme inhibitor activity, 0045980 negative regulation of nucleotide metabolic process, 0005739 mitochondrion; PDB: 1GMJ_B 1OHH_H 1HF9_B 2V7Q_J.
