TACC3/ERIC1 [C2]

TACC3 (Transforming acidic coiled-coil-containing protein 3), also known as ERIC1, belongs to the TACC family. TACC family members TACC1, TACC2, and TACC3 map very closely to the corresponding FGFR1, FGFR2, FGFR3 genes on chromosomes 8, 10, and 4. Subsequently, since they are phylogenetically related, it is proposed that TACC and FGFR have similar roles in cell growth and differentiation. TACC3 plays a critical role in microtubule nucleation at the centrosome. It is involved in the regulation of microtubule nucleation at the centrosome and functions in the stabilization of the γ-tubulin ring complex assembly. It plays an essential role in spindle assembly and centrosome integrity during mitosis, as well as for cellular survival. It may act as a potential therapeutic target in cancer cells. TACC3 is aberrantly expressed in a variety of human cancers. It acts as a driver of tumorigenesis as well as an inducer of oncogenic EMT.
