- Abstract
Abstract: ELL-associated protein 30 (EAP30) was initially characterized as a component of the Holo–ELL complex, which contains the elongation factor ELL. Both ELL and Holo–ELL stimulate RNA pol II elongation in vitro. However, ELL and not Holo–ELL inhibits RNA pol II initiation. It is not clear how these two discrete functions of ELL are regulated. Here we report that mini-chromosome maintenance 2 (MCM2) binds to EAP30 and show that MCM2 competes with ELL for binding to EAP30 thus potentially modulating the stability of Holo–ELL.
