ID:GRL1A_HUMAN DESCRIPTION: RecName: Full=DNA-directed RNA polymerase II subunit GRINL1A; AltName: Full=DNA-directed RNA polymerase II subunit M; AltName: Full=Glutamate receptor-like protein 1A; FUNCTION: Isoform 1 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. Isoform 1 may play a role in the Mediator complex-dependent regulation of transcription activation. Isoform 1 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. SUBUNIT: Isoform 1 is a component of the Pol II(G) complex, which contains the RNA polymerase II (Pol II) core complex subunits and POLR2M isoform 1. Pol II(G) appears to be an abundant form of Pol II. SUBCELLULAR LOCATION: Isoform 1: Nucleus (Probable). TISSUE SPECIFICITY: Detected in adult an fetal brain. Detected in heart, kidney, skeletal muscle, small intestine, lung, prostate and testis. MISCELLANEOUS: The adjacent MYZAP and POLR2M genes are part of a complex transcription unit. The respective transcripts derive from different promoters and are alternatively spliced. In human, some transcripts of the upstream promoter of MYZAP use exons of the downstream POLR2M gene. SIMILARITY: Belongs to the GRINL1 family.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
