Specifically recognizes growing microtubule minus-ends and autonomously decorates and stabilizes microtubule lattice formed by microtubule minus-end polymerization (PubMed:24486153, PubMed:24706919). Acts on free microtubule minus-ends that are not capped by microtubule-nucleating proteins or other factors and protects microtubule minus-ends from depolymerization (PubMed:24486153, PubMed:24706919). In addition, it also reduces the velocity of microtubule polymerization (PubMed:24486153, PubMed:24706919). Through the microtubule cytoskeleton, also regulates the organization of cellular organelles including the Golgi and the early endosomes (PubMed:27666745). Essential for the tethering, but not for nucleation of non-centrosomal microtubules at the Golgi: together with Golgi-associated proteins AKAP9 and PDE4DIP, required to tether non-centrosomal minus-end microtubules to the Golgi, an important step for polarized cell movement (PubMed:27666745). Also acts as a regulator of neuronal polarity and development: localizes to non-centrosomal microtubule minus-ends in neurons and stabilizes non-centrosomal microtubules, which is required for neuronal polarity, axon specification and dendritic branch formation (PubMed:24908486). Through the microtubule cytoskeleton, regulates the autophagosome transport (PubMed:28726242). {ECO:0000269|PubMed:23169647, ECO:0000269|PubMed:24486153, ECO:0000269|PubMed:24706919, ECO:0000269|PubMed:24908486, ECO:0000269|PubMed:27666745, ECO:0000269|PubMed:28726242}. |CAMSAP CKK| |CAMSAP CH| |CH| |microtubule end| |microtubule minus-end| |microtubule minus-end binding| |regulation of Golgi organization| |negative regulation of microtubule depolymerization| |spectrin binding| |regulation of microtubule depolymerization| |negative regulation of microtubule polymerization or depolymerization| |regulation of microtubule polymerization| |cytoplasmic microtubule organization| |negative regulation of protein depolymerization| |negative regulation of protein complex disassembly| |regulation of microtubule polymerization or depolymerization| |regulation of protein depolymerization| |regulation of protein complex disassembly| |negative regulation of supramolecular fiber organization| |negative regulation of cytoskeleton organization| |regulation of dendrite development| |regulation of microtubule cytoskeleton organization| |calmodulin binding| |regulation of microtubule-based process| |regulation of protein polymerization| |regulation of supramolecular fiber organization| |negative regulation of organelle organization| |axon development| |regulation of protein complex assembly| |supramolecular fiber organization| |microtubule cytoskeleton organization| |centrosome| |regulation of neuron projection development| |regulation of cytoskeleton organization| |regulation of neuron differentiation| |neuron projection development| |microtubule-based process| |regulation of plasma membrane bounded cell projection organization| |negative regulation of cellular component organization| |regulation of cell projection organization| |neuron development| |regulation of neurogenesis| |regulation of nervous system development| |regulation of cell development| |regulation of cellular component biogenesis| |Golgi apparatus| |neuron differentiation| |cytoskeleton organization| |plasma membrane bounded cell projection organization| |cell projection organization| |regulation of organelle organization| |generation of neurons| |neurogenesis| |cell development| |regulation of cell differentiation| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp225|Celastrol 0.12μM R05 exp225]]|-1.93| |[[:results:exp81|Selumetinib 20μM R02 exp81]]|-1.7| |[[:results:exp477|DKK1 89ng/ml R08 exp477]]|1.76| No correlation found to any other genes in chemogenomics.
