Comments and Description Text from UniProtKB


	ID: IFN21_HUMAN DESCRIPTION: RecName: Full=Interferon alpha-21; Short=IFN-alpha-21; AltName: Full=Interferon alpha-F; Short=LeIF F; Flags: Precursor; FUNCTION: Produced by macrophages, IFN-alpha have antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. SUBCELLULAR LOCATION: Secreted. SIMILARITY: Belongs to the alpha/beta interferon family. SEQUENCE CAUTION: Sequence=AAA36041.1; Type=Erroneous initiation;

Primer design for this transcript

Primer3Plus can design qPCR Primers that straddle exon-exon-junctions, which amplify only cDNA, not genomic DNA.
Click here to load the transcript sequence and exon structure into Primer3Plus

Exonprimer can design one pair of Sanger sequencing primers around every exon, located in non-genic sequence.

mRNA Secondary Structure of 3' and 5' UTRs

Region	Fold Energy	Bases	Energy/Base	Display As
5' UTR	-7.40	48	-0.154	Picture	PostScript	Text
3' UTR	-74.20	406	-0.183	Picture	PostScript	Text

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.

ModBase Predicted Comparative 3D Structure on P01568


Front	Top	Side

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.
