About This Section

Entrez Gene summary for LAMB3 Gene:

The product encoded by this gene is a laminin that belongs to a family of basement membrane proteins. This protein

is a beta subunit laminin, which together with an alpha and a gamma subunit, forms laminin-5. Mutations in this

gene cause epidermolysis bullosa junctional Herlitz type, and generalized atrophic benign epidermolysis bullosa,

diseases that are characterized by blistering of the skin. Multiple alternatively spliced transcript variants

that encode the same protein have been found for this gene. (provided by RefSeq, Jul 2008)

GeneCards Summary for LAMB3 Gene:

LAMB3 (laminin, beta 3) is a protein-coding gene. Diseases associated with LAMB3 include maternal uniparental disomy of chromosome 1, and lamb3-related junctional epidermolysis bullosa, and among its related super-pathways are Syndecan interactions and Focal Adhesion. GO annotations related to this gene include protein binding and structural molecule activity. An important paralog of this gene is LAMC1.

UniProtKB/Swiss-Prot: LAMB3_HUMAN, Q13751

Function: Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration

and organization of cells into tissues during embryonic development by interacting with other extracellular

matrix components

About This Section

UniProtKB/Swiss-Prot: LAMB3_HUMAN, Q13751 (See protein sequence)

Recommended Name: Laminin subunit beta-3 precursor

Size: 1172 amino acids; 129572 Da

Subunit: Laminin is a complex glycoprotein, consisting of three different polypeptide chains (alpha, beta, gamma),

which are bound to each other by disulfide bonds into a cross-shaped molecule comprising one long and three short

arms with globules at each end. Beta-3 is a subunit of laminin-5 (laminin-332 or epiligrin/kalinin/nicein).

Epidermolysis bullosa, junctional, Herlitz type (H-JEB) [MIM:226700]: An infantile and lethal form of

junctional epidermolysis bullosa, a group of blistering skin diseases characterized by tissue separation which

occurs within the dermo-epidermal basement In the Herlitz type, death occurs usually within the first six months

of life. Occasionally, children survive to teens. It is marked by bullous lesions at birth and extensive

denudation of skin and mucous membranes that may be hemorrhagic. Note=The disease is caused by mutations

affecting the gene represented in this entry

Generalized atrophic benign epidermolysis bullosa (GABEB) [MIM:226650]: A non-lethal, adult form of

junctional epidermolysis bullosa characterized by life-long blistering of the skin, associated with hair and

tooth abnormalities. Note=The disease is caused by mutations affecting the gene represented in this entry
