MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Cofactor D is one of four proteins (cofactors A, D, E, and C) involved in the pathway leading to correctly folded beta-tubulin from folding intermediates. Cofactors A and D are believed to play a role in capturing and stabilizing beta-tubulin intermediates in a quasi-native confirmation. Cofactor E binds to the cofactor D/beta-tubulin complex; interaction with cofactor C then causes the release of beta-tubulin polypeptides that are committed to the native state.

Protein Function and Prediction

Tbcd encodes tubulin folding cofactor D (TBCD), a member of the tubulin synthesis complex (1). TBCD modulates microtubule dynamics by sequestering β-tubulin from GTP-bound αβ-heterodimers (2). Fanarraga et al. determined that TBCD has a role in centriologenesis, spindle organization, and cell abcission (1). TBCD depletion results in mitotic aberrations and incomplete microtubule retraction at the midbody during cytokinesis (1). Human TBCD is proposed to recruite cytosolic centrosomal proteins (e.g., pericentrin or γ-tubulin) to the mitotic spindle (3). Mutations in TBCD have been linked to chromosome number aberrations, G1/S blockage, spindle pole body separation, and abnormal cytokinesis in yeast, Arabidopsis, and Caenorhabditis elegans (4-10). TBCD is ubiquitously expressed in human tissues tested (i.e., brain, spinal cord, liver, pancreas, kidney, spleen, heart, lung, skeletal muscle, testis, ovary, fetal brain, and fetal liver) by RT-PCR followed by ELISA (11). The TBCD protein is localized throughout the cell (2). Further studies determined that TBCD is concentrated at the centrosome and midbody (1). Furthermore, TBCD localization is cell-cycle-specific with localization on the daughter centriole at G1 and on procentrioles by S; TBCD disappears from older centrioles at telophase as the protein is recruited to the midbody (1). At the onset of the centrosome duplication cycle, TBCD is recruited to the centriole replication site (1). During cytokinesis TBCD is localized at Fleming bodies at the midbody (1).
