Brain tissue expression of GNRH1 - Summary

GENERAL INFORMATIONⁱ General description of the gene and the encoded protein(s) using information from HGNC and Ensembl, as well as predictions made by the Human Protein Atlas project.
Human gene nameⁱ Official gene symbol, which is typically a short form of the gene name, according to HGNC.	GNRH1
Mouse gene name	Gnrh1
Human gene descriptionⁱ Full gene name according to HGNC.	Gonadotropin releasing hormone 1
Predicted locationⁱ All transcripts of all genes have been analyzed regarding the location(s) of corresponding protein based on prediction methods for signal peptides and transmembrane regions. Genes with at least one transcript predicted to encode a secreted protein, according to prediction methods or to UniProt location data, have been further annotated and classified with the aim to determine if the corresponding protein(s) are secreted or actually retained in intracellular locations or membrane-attached. Remaining genes, with no transcript predicted to encode a secreted protein, will be assigned the prediction-based location(s). The annotated location overrules the predicted location, so that a gene encoding a predicted secreted protein that has been annotated as intracellular will have intracellular as the final location.

HUMAN PROTEIN ATLAS INFORMATION
Tissue specificityⁱ The RNA specificity category is based on mRNA expression levels in the analyzed samples based on a combination of data from HPA, GTEX and FANTOM5. The categories include: tissue enriched, group enriched, tissue enhanced, low tissue specificity and not detected. The Tissue classification is based on 37 human tissue types, where brain is represented by the highest expression value among the human brain regions (including spinal cord and corpus callosum that is excluded from the regional classification based on 10 main brain regions). The combination of tissue and regional classification can be found here Read more	Tissue enhanced (brain)
	Human brain	Pig brain	Mouse brain
Regional specificityⁱ The regional specificity category is based on mRNA expression levels in the analyzed brain samples, grouped into 10 main brain regions and calculated for the three different species. The human brain expression profile is based on a combination of data from GTEX and FANTOM5. The specificity categories include: regionally enriched, group enriched, regionally enhanced, low regional specificity and not detected. The classification rules are the same used for the tissue specificity category. Read more	Group enriched (basal ganglia, cerebellum)	Group enriched (basal ganglia, hypothalamus)	Group enriched (basal ganglia, hypothalamus, olfactory region)
Regional distributionⁱ The regional distribution category is based on mRNA expression detected above cut off or not in the analyzed brain samples, grouped into 10 main brain regions and calculated for the three different species. The human brain expression is based on a combination of data from GTEX and FANTOM5. The distribution categories include: detected in all, detected in many, detected in some, detected in single and not detected. The classification rules are the same used for the tissue distribution category. Read more	Detected in all	Detected in some	Detected in many
Protein profileⁱ A summary of the overall protein localization across the analyzed brain tissue. The summary is based on manual annotation. Mouse brain profiles includes a more extensive summary of the protein location while summaries with only human protein profile are more limited and are based on imported data/images from the Tissue Atlas stainings that has undergone an additional brain-centric curation step. Read more	Protein detected in a subset of neurons in several brain regions, distinct in hypothalamus. Projection positivity observed in most brain regions.
