Genes affected
CAMSAP1 (HGNC:19946): (calmodulin regulated spectrin associated protein 1) Enables microtubule minus-end binding activity and spectrin binding activity. Involved in several processes, including neuron projection development; regulation of cell morphogenesis; and regulation of microtubule polymerization. Located in microtubule. Colocalizes with microtubule minus-end. [provided by Alliance of Genome Resources, Apr 2022]
