Subcellular - PLCB4 - The Human Protein Atlas

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.
Gene nameⁱ Official gene symbol, which is typically a short form of the gene name, according to HGNC.	PLCB4
Gene descriptionⁱ Full gene name according to HGNC.	Phospholipase C beta 4
Protein classⁱ Assigned HPA protein class(es) for the encoded protein(s). Read more	Disease related genes Enzymes Human disease related genes Metabolic proteins Potential drug targets
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.	Intracellular
Number of transcriptsⁱ Number of protein-coding transcripts from the gene as defined by Ensembl.	39

HUMAN PROTEIN ATLAS INFORMATIONⁱ Summary of RNA expression and protein localization based on data generated within the Human Protein Atlas project.
Main locationⁱ Main subcellular location(s) and reliability score(s) for the encoded protein(s) in human cells. The main location(s) may be characterized by presence in all tested cell lines and/or ihigher staining intensity compared to the potential additional location(s). If available, links to overrepresentation analyses in Reactome, a free, open-source, curated and peer reviewed biological pathway database, are provided. An analysis is done for the corresponding gene set of the proteome localizing to the main and additional locations of the protein on this page, respectively.	Localized to the Plasma membrane (supported), Microtubules (uncertain), Primary cilium (uncertain), Basal body (uncertain)
Additional locationⁱ Additonal subcellular location(s) for the encoded protein(s) in human cells. The additional location(s) may not be present i all cell lines and may have lower staining intensity compared to the main location(s). If available, links to overrepresentation analyses in Reactome, a free, open-source, curated and peer reviewed biological pathway database, are provided. An analysis is done for the corresponding gene set of the proteome localizing to the main and additional locations of the protein on this page, respectively.	In addition localized to the Nucleoplasm (uncertain), Actin filaments (uncertain), Cytokinetic bridge (uncertain), Centrosome (uncertain), Acrosome (approved), Equatorial segment (approved), Mid piece (approved), Principal piece (approved), End piece (approved)
Single-cell variationⁱ Single-cell variations in protein expression levels or distribution observed between cells within the same images of human cells stained by immunocytochemistry.	Single-cell variation in protein expression observed.
Reliability scoreⁱ Overall gene reliability score for the subcellular location(s) of the encoded protein(s). The score indicates the level of reliability of the annotated protein localization based on agreement with available experimental gene/protein characterization data in the UniProtKB/Swiss-Prot database and presence of antibody validation assays for immunocytochemistry.	Uncertain
