CAMSAP1Calmodulin-regulated spectrin-associated protein 1 is a human protein encoded by the gene CAMSAP1. Like other CAMSAP-family proteins, it is a microtubule minus-end anchor, and binds microtubules through its CKK domain.Clinical significanceCAMSAP1 is vital for neuron polarisation, and so mice that lack CAMSAP1 die of epileptic seizures.
