Protein RCC2 also known as telophase disk protein of 60 kDa (TD-60) or RCC1-like protein TD-60 is a protein that in humans is encoded by the RCC2gene.[1][2][3]
Function
RCC2 has structural similarity to RCC1, and has been shown to have weak guanine nucleotide exchange factor (GEF) activity on the small GTPase Rac.[2] TD-60 has also been shown to interact with the Chromosomal Passenger Complex (CPC), and to activate the catalytic component of the CPC, Aurora B, in the presence of microtubules.[4][5]
