Pericentrin (kendrin), also known as PCNT, is a protein which in humans is encoded by the PCNT gene.^[1][2][3]

Function

The protein encoded by this gene binds to calmodulin and is expressed in the centrosome. It is an integral component of the pericentriolar material (PCM). The protein contains a series of coiled coil domains and a highly conserved PCM targeting motif called the PACT domain near its C-terminus^[4]. The protein interacts with the microtubule nucleation component γ-tubulin and is likely important to normal functioning of the centrosomes, cytoskeleton, and cell cycle progression.^[1]

Interactions

PCNT has been shown to interact with PCM1.^[5]
