What pLDDT means and how to read it

Function

Component of the chaperonin-containing T-complex (TRiC), a molecular chaperone complex that assists the folding of actin, tubulin and other proteins upon ATP hydrolysis (PubMed:25467444, PubMed:36493755, PubMed:35449234, PubMed:37193829). The TRiC complex mediates the folding of WRAP53/TCAB1, thereby regulating telomere maintenance (PubMed:25467444). As part of the TRiC complex may play a role in the assembly of BBSome, a complex involved in ciliogenesis regulating transports vesicles to the cilia (PubMed:20080638)

Subunit structure

Component of the chaperonin-containing T-complex (TRiC), a hexadecamer composed of two identical back-to-back stacked rings enclosing a protein folding chamber (PubMed:1630492, PubMed:20080638, PubMed:25467444, PubMed:36493755, PubMed:35449234, PubMed:37193829). Each ring is made up of eight different subunits: TCP1/CCT1, CCT2, CCT3, CCT4, CCT5, CCT6A/CCT6, CCT7, CCT8 (PubMed:36493755,…
