Function

Downstream of MCC fate acquisition, Cdk2 is required to initiate and maintain the MCC gene expression program during ciliogenesis. Consistently, MCCs driven to differentiate in the absence of Cdk2 activity fail to undergo ciliogenesis (30152757). CDK2 localized to basal body (25613900).

Model organism evidence

Mus musculus (2 references)

Pyrogallol-Phloroglucinol-6, 6-Bieckol Restored Primary Cilia Length, Which Was Decreased by High-Fat Diet in Visceral Adipose Tissue, and Decreased Adipogenesis.

We use transgenic mice and primary airway epithelial cell culture to show that Cdk2, the kinase responsible for the G1 to S phase transition, is also required in MCCs to initiate motile ciliogenesis.
