Anti-CCT3 antibodies are used in the immunodetection of the protein chaperonin containing TCP1 subunit 3. In humans, the canonical protein has a reported length of 545 amino acid residues and a mass of 60.5 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of a the TCP-1 chaperonin protein family, CCT3 is a known component of the chaperonin-containing T-complex (TRiC), a molecular chaperone complex that assists the folding of proteins upon ATP hydrolysis. Synonyms for this target antigen include CCTG, PIG48, TCP-1-gamma, TRIC5, T-complex protein 1 subunit gamma, and CCT-gamma.
