Description

Due to the crowded envirnoment within the cell, many proteins must interact with molecular chaperones to attain their native conformation (reviewed in Young et al., 2004). Chaperones recognize and associate with proteins in their non-native state and facilitate their folding by stabilizing the conformation of productive folding intermediates. Chaperones that take part broadly in de novo protein folding, such as the Hsp70s and the chaperonins, facilitate the folding process through cycles of substrate binding and release regulated by their ATPase activity (see Young et al., 2004; Spiess et al., 2004; Bigotti and Clarke, 2008).

R-HSA-389954 (Reactome) Group II chaperonins enclose substrate proteins following substrate binding through the formation of a "built- in" lid over the central cavity. Upon ATP binding, lid formation is triggered by the transition state of ATP hydrolysis (Meyer, et al., 2003). In the case of CCT-mediated tubulin folding, one or more rounds of ATP hydrolysis are likely required before the association of non-exchangeable GTP with chaperonin-bound alpha tubulin.
R-HSA-389955 (Reactome) Factor A:beta tubulin complex act as a reservoir capable of accepting or delivering its target tubulin protein to cofactor D (Tian et al., 1997). In the reverse reaction, Cofactor A may displace cofactor D in a cofactor D:beta tubulin complex.
R-HSA-389956 (Reactome) Beta-tubulin folding intermediates generated via ATP-dependent interaction with TriC/CCT are captured by tubulin-specific chaperones A and D (TBCA and TBCD) (Tian et al. 1996, Tian et al. 1997) in a reversible reaction forming tubulin intermediate/cofactor complexes Factor A:beta tubulin or Factor D:beta tubulin. TBCD is involved in the tubulin-folding pathway, acting as a GTPase activating protein (GAP) for beta-tubulin. The ADP-ribosylation factor-like protein 2 (ARL2) is able to down-regulate TBCD specifically, thus preventing microtuble disruption (Bhamidipati et al. 2000, Tian et al. 2010).
R-HSA-389961 (Reactome) The interaction between CCT and unfolded target proteins is thought to occur when CCT is in its ADP-bound state. ADP is then exchanged for ATP in CCT.
R-HSA-389963 (Reactome) The factor B:alpha tubulin complex act as a reservoir capable of accepting or delivering alpha tubulin to cofactor E (Tian et al., 1997). In the reverse reaction, cofactor B may displace cofactor E in the cofactor E:alpha tubulin complex.
R-HSA-389964 (Reactome) Entry of cofactor C to the factor E:alpha tubulin: factor D:beta tubulin complex generates the active alpha:beta-supercomplex (Tian et al., 1997).
R-HSA-389969 (Reactome) Beta-tubulin folding intermediates generated via ATP-dependent interaction with TriC/CCT are captured by tubulin-specific chaperones A and D (TBCA and TBCD) (Tian et al. 1996, Tian et al. 1997) in a reversible reaction forming tubulin intermediate/cofactor complexes Factor A:beta tubulin or Factor D:beta tubulin. TBCD is involved in the tubulin-folding pathway, acting as a GTPase activating protein (GAP) for beta-tubulin. The ADP-ribosylation factor-like protein 2 (ARL2) is able to down-regulate TBCD specifically, thus preventing microtuble disruption (Bhamidipati et al. 2000, Tian et al. 2010).
R-HSA-389970 (Reactome) Unfolded actins and tubulins compete efficiently for binding to TriC/CCT and their chaperonin binding sites appear to be at least in part overlapping (Melki et al., 1993).
R-HSA-389972 (Reactome) Quasi-native alpha-tubulin folding intermediates generated via ATP-dependent interaction with CCT (Tian et al., 1995) are captured in a reversible reaction by cofactors B and/or E (Tian et al., 1997), forming the tubulin intermediate/cofactor complexes Factor B:alpha tubulin or Factor E:alpha tubulin.
R-HSA-389974 (Reactome) Beta tubulin within the active (Factor E:alpha tubulin: Factor D:beta tubulin:Factor C )-supercomplex hydrolyzes GTP. This results in the dissociation of the complex and the release of the native tubulin heterodimer (Tian et al., 1997).
R-HSA-389976 (Reactome) Factor E:alpha tubulin and Factor D:beta tubulin interact with each other in a reversible reaction to form the complex (Factor E alpha tubulin:Factor D:beta tubulin) (Tian et al., 1997).
R-HSA-389978 (Reactome) Quasi-native alpha-tubulin folding intermediates generated via ATP-dependent interaction with CCT (Tian et al., 1995) are captured in a reversible reaction by cofactors B and/or E (Tian et al., 1997), forming the tubulin intermediate/cofactor complexes Factor B:alpha tubulin or Factor E:alpha tubulin.
R-HSA-389980 (Reactome) During the synthesis of actin and tubulin, the nascent ribosome-associated chains bind to the heteromeric chaperone protein, prefoldin (PFD) (Hansen et al., 1999).
R-HSA-390453 (Reactome) TriC/CCT-mediated beta-actin folding involves rapid ATP-independent formation of a binary complex, followed by a slower ATP-dependent release of the native product (Gao et al., 1992). Group II chaperonins enclose substrate proteins following substrate binding through the formation of a "built- in" lid over the central cavity. Upon ATP binding, lid formation is triggered by the transition state of ATP hydrolysis (Meyer, et al., 2003).
R-HSA-390459 (Reactome) The interaction between CCT and unfolded target proteins is thought to occur when CCT is in its ADP-bound state. ADP is then exchanged for ATP in CCT.
R-HSA-390470 (Reactome) A combination of proteomic and bioinformatics analyses of TRiC substrates has revealed that they have complex topologies that are slow folding and aggregation prone (Yam et al., 2008). These substrates are also enriched in proteins that belong to oligomeric assemblies suggesting that TRiC plays a role in promoting complex assembly (Yam et al., 2008). Two possible mechanisms describing the role of TriC have been suggested (Yam et al., 2008). The processes of TRiC-mediated folding and assembly could be directly coupled, or TRiC could fold monomeric subunits and hold them in an assembly-competent state until they associate with the appropriate partner subunits. The complete list of TriC subsrates is not yet known. Many of its substrates that are targeted during biosynthesis are conserved between mammals and yeast (Yam et al. 2008).
