Family

DNA-directed RNA polymerase II subunit GRINL1 (IPR026213)

Short name: GRINL1

Family relationships

None.

Description

GRINL1 family consists of GRINL1A and GRINL1B. GRINL1 appears to be a stable component of the Pol II (G) complex form of RNA polymerase II (Pol II). Pol II synthesizes mRNA precursors and many functional non-coding RNAs and is the central component of the basal RNA polymerase II transcription machinery. GRINL1 may play a role in the Mediator complex-dependent regulation of transcription activation. It acts in vitro as a negative regulator of transcriptional activation; this repression is relieved by the Mediator complex, which restores Pol II(G) activator-dependent transcription to a level equivalent to that of Pol II [PMID: 16769904].
