General Information
Term microtubule nucleation ID (Ontology) GO:0007020 (Gene Ontology)
Definition The process in which tubulin alpha-beta heterodimers begin aggregation to form an oligomeric tubulin structure (a microtubule seed). Microtubule nucleation is the initiating step in the formation of a microtubule in the absence of any existing microtubules ('de novo' microtubule formation).[ ISBN:0815316194 PubMed:12517712 ]
