RNA tissue category
The RNA tissue category is based on mRNA expression levels in 32 different tissues ( RNA assay description).
The categories include: tissue enriched, group enriched, tissue enhanced, expressed in all, not detected, and mixed.
RNA tissue category is calculated separately both for internally generated Human Protein Atlas (HPA) RNA-seq data, as
well as RNA-seq data from the Genotype-Tissue Expression ( GTEx) consortium.
Protein evidence
Protein evidence scores are generated from several independent sources
and are classified as evidence at i) protein level, ii) transcript level, iii) no evidence or iv) not available.
Protein localization
A summary of the overall protein expression pattern across the analyzed tissues. The summary is based on knowledge-based
annotation ( Annotation description). For genes pending
knowledge-based annotation, the protein localization refers to the antibody staining pattern.
"RNA-based expert annotation gave inconconclusive results" is shown for genes analyzed with a knowledge-based approach where
available RNA-seq and gene/protein characterization data has been evaluated as not sufficient in combination with
immunohistochemistry-data to yield a reliable estimation of the protein expression profile.

Data reliability description
Standardized explanatory sentences with additional information required for full understanding of the
knowledge-based expression profile. Currently, not all genes have been analyzed by knowledge-based
annotation, indicated by "Pending RNA-based expert annotation", when applicable.
Data reliability
Data reliability score ( score description), divided into supportive (premium)
or uncertain (not premium), is based on consistency between the staining pattern of one antibody or several
antibodies with RNA-seq data and available gene/protein characterization data.
|
Data reliability description |
Antibody staining mainly consistent with RNA expression data. Presumed off target binding observed and disregarded. |
Data reliability |
Supportive based on 1 antibody.

PROTEIN EXPRESSION OVERVIEW
? »
|
Protein expression data is shown for each of the 44 tissues. Color-coding is based on 13 tissue groups, each consisting
of tissues with common functional features. Mouse-over function shows protein score for analyzed cell types found in a
selected tissue. To access image data click on tissue name or bar. Annotation of protein expression is described in
detail in Assays & annotation.
For genes with available protein data for which a knowledge-based annotation could not be performed, no protein
expression data is displayed in the protein expression data overview, however, all immunohistochemical images are
still available and the annotation data can be found under Primary data.

Gene name |
B4GALT2 (HGNC Symbol) |
Synonyms |
beta4Gal-T2 |
Description |
UDP-Gal:betaGlcNAc beta 1,4- galactosyltransferase, polypeptide 2 (HGNC Symbol) |
Entrez gene summary |
This gene is one of seven beta-1,4-galactosyltransferase (beta4GalT) genes. They encode type II membrane-bound glycoproteins that appear to have exclusive specificity for the donor substrate UDP-galactose; all transfer galactose in a beta1,4 linkage to similar acceptor sugars: GlcNAc, Glc, and Xyl. Each beta4GalT has a distinct function in the biosynthesis of different glycoconjugates and saccharide structures. As type II membrane proteins, they have an N-terminal hydrophobic signal sequence that directs the protein to the Golgi apparatus and which then remains uncleaved to function as a transmembrane anchor. By sequence similarity, the beta4GalTs form four groups: beta4GalT1 and beta4GalT2, beta4GalT3 and beta4GalT4, beta4GalT5 and beta4GalT6, and beta4GalT7. The enzyme encoded by this gene synthesizes N-acetyllactosamine in glycolipids and glycoproteins. Its substrate specificity is affected by alpha-lactalbumin but it is not expressed in lactating mammary tissue. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2011] |

PROTEIN BROWSER
? »
|
The protein browser displays the antigen location on the target protein(s) and the features of the target protein. The
tabs at the top of the protein view section can be used to switch between the different splice variants to which
an antigen has been mapped.
At the top of the view, the position of the antigen (identified by the corresponding HPA identifier) is shown as a green
bar. A yellow triangle on the bar indicates a <100% sequence identity to the protein target.
Under the antigens, the maximum percent sequence identity of the protein to all other proteins from other human genes is
displayed, using a sliding window of 10 aa residues (HsID 10) or 50 aa residues
(HsID 50) ( read more).
If a signal peptide is predicted by a majority of the signal peptide predictors SPOCTOPUS,
SignalP 4.0, and
Phobius (turquoise)
and/or transmembrane regions (orange) are predicted by MDM, these are displayed.
Low complexity regions are shown in yellow
and InterPro regions in green. Common (purple) and
unique (grey) regions between different splice variants of the gene are also displayed
( read more), and at the
bottom of the protein view is the protein scale.

The protein information section displays alternative protein-coding transcripts (splice variants) encoded by this
gene according to the Ensembl database.
The ENSP identifier links to the Ensembl website protein summary, while the ENST identifier links to the Ensembl website transcript summary
for the selected splice variant. The data in the UniProt column can be expanded to show links to all matching
UniProt identifiers for this protein.
The protein classes assigned to this protein are shown if expanding the data in the
protein class column. Parent protein classes are in bold font and subclasses are listed under the parent class.
The Gene Ontology terms assigned to this protein are
listed if expanding the Gene ontology column.
The length of the protein (amino acid residues according to Ensembl), molecular mass (kDalton), predicted signal peptide (according to a
majority of the signal peptide predictors SPOCTOPUS,
SignalP 4.0 and
Phobius) and the number of predicted transmembrane region(s)
(according to MDM) are also reported.
