Summaries for TBCB Gene

GeneCards Summary for TBCB Gene

TBCB (Tubulin Folding Cofactor B) is a Protein Coding gene. Diseases associated with TBCB include Hypoparathyroidism-Retardation-Dysmorphism Syndrome. Among its related pathways are Chaperonin-mediated protein folding and Cooperation of Prefoldin and TriC/CCT in actin and tubulin folding. An important paralog of this gene is CLIP1.

UniProtKB/Swiss-Prot for TBCB Gene

  • Binds to alpha-tubulin folding intermediates after their interaction with cytosolic chaperonin in the pathway leading from newly synthesized tubulin to properly folded heterodimer (PubMed:9265649). Involved in regulation of tubulin heterodimer dissociation. May function as a negative regulator of axonal growth (By similarity).

    244 amino acids
    Molecular mass:
    27326 Da
    Quaternary structure:
    • Supercomplex made of cofactors A to E. Cofactors A and D function by capturing and stabilizing tubulin in a quasi-native conformation. Cofactor E binds to the cofactor D-tubulin complex; interaction with cofactor C then causes the release of tubulin polypeptides that are committed to the native state (PubMed:9265649). Cofactors B and E can form a heterodimer which binds to alpha-tubulin and enhances their ability to dissociate tubulin heterodimers (By similarity). Interacts with GAN (PubMed:16303566). Interacts with DCTN1 (PubMed:22777741).
