Centrin-2 is a protein that in humans is encoded by the CETN2 gene.^[5]^[6]^[7] It belongs to the centrin family of proteins.

Centrin-2 belongs to a family of calcium-binding proteins and is a structural component of the centrosome. The high level of conservation from algae to humans and its association with the centrosome suggested that centrin-2 plays a fundamental role in the structure and function of the microtubule-organizing center, possibly required for the proper duplication and segregation of the centrosome.^[7]

Interactions edit

CETN2 has been shown to interact with XPC^[8] and SFI1.^[9]
