General Information

Term

positive regulation of microtubule nucleation

ID (Ontology)

GO:0090063 (Gene Ontology)

Definition

Any process that increases the rate, frequency or extent of microtubule nucleation. Microtubule nucleation is the 'de novo' formation of a microtubule, in which tubulin heterodimers form metastable oligomeric aggregates, some of which go on to support formation of a complete microtubule. Microtubule nucleation usually occurs from a specific site within a cell.
