DNA-directed RNA polymerase II subunit GRINL1A is a protein that in humans is encoded by the POLR2Mgene (previously GRINL1A).[5] This protein is a component of Pol II(G), a variant form of the RNA polymerase II complex.[5]
This gene (GRINL1A) is part of a complex transcript unit that includes the gene for GRINL1A combined protein (Gcom1). Transcription of this gene occurs at a downstream promoter, with at least three different alternatively spliced variants, grouped together as Gdown for GRINL1A downstream transcripts. The Gcom1 gene uses an upstream promoter for transcription and also has multiple alternatively spliced variants.[5]
