| 词条 | Actin nucleation core |
| 释义 |
An actin nucleation core is a protein trimer with three actin monomers. It is called a nucleation core because it leads to the energetically favorable elongation reaction once a tetramer is formed from a trimer. Actin protein dimers and trimers are energetically unfavorable.[1] References1. ^{{cite journal|doi=10.1074/jbc.M112.406744|pmid=23148219|pmc = 3537046|year=2013|last1=Liu|first1=S.
