Tubulin Folding Cofactor B (TBCB) is a protein that plays a crucial role in the proper folding and assembly of tubulin, which is a key component of the microtubule cytoskeleton. Microtubules are essential for various cellular processes, including cell division, intracellular transport, and maintenance of cell shape.
The TBCB gene, also known as CKAP1 (Cytoskeleton-Associated Protein 1), encodes the TBCB protein. This gene is located on chromosome 19 in humans . The TBCB protein is involved in the folding of alpha-tubulin intermediates after their interaction with cytosolic chaperonin, leading to the formation of properly folded tubulin heterodimers .
TBCB binds to alpha-tubulin folding intermediates and is involved in the regulation of tubulin heterodimer dissociation . It may also function as a negative regulator of axonal growth . The protein is part of a group of cofactors (TBCA-TBCE) that play a role in microtubule biosynthesis . Specifically, TBCB enhances the folding of alpha-tubulin and contributes to the polymerization of microtubules .
The mouse anti-human TBCB antibody is commonly used in research to study the expression and function of TBCB in various biological contexts. This antibody is suitable for applications such as Western Blot (WB), Immunoprecipitation (IP), Immunohistochemistry (IHC), and Immunocytochemistry (ICC) . It reacts with both mouse and human samples, making it a versatile tool for studying TBCB in different model systems .
