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. |

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.

Description |
Laminin, gamma 1 (formerly LAMB2) (HGNC Symbol) |
Entrez gene summary |
Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins, composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively), have a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. Several isoforms of each chain have been described. Different alpha, beta and gamma chain isomers combine to give rise to different heterotrimeric laminin isoforms which are designated by Arabic numerals in the order of their discovery, i.e. alpha1beta1gamma1 heterotrimer is laminin 1. The biological functions of the different chains and trimer molecules are largely unknown, but some of the chains have been shown to differ with respect to their tissue distribution, presumably reflecting diverse functions in vivo. This gene encodes the gamma chain isoform laminin, gamma 1. The gamma 1 chain, formerly thought to be a beta chain, contains structural domains similar to beta chains, however, lacks the short alpha region separating domains I and II. The structural organization of this gene also suggested that it had diverged considerably from the beta chain genes. Embryos of transgenic mice in which both alleles of the gamma 1 chain gene were inactivated by homologous recombination, lacked basement membranes, indicating that laminin, gamma 1 chain is necessary for laminin heterotrimer assembly. It has been inferred by analogy with the strikingly similar 3' UTR sequence in mouse laminin gamma 1 cDNA, that multiple polyadenylation sites are utilized in human to generate the 2 different sized mRNAs (5.5 and 7.5 kb) seen on Northern analysis.

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.
