Supplementary information

Laminin subunit alpha-3 also known by the gene name LAMA3 is a critical component of the extracellular matrix. The protein has a molecular weight of approximately 400 kDa. LAMA3 is primarily expressed in epithelial tissues contributing significantly to the structural integrity of basement membranes. The protein often partners with other laminin subunits to form different laminin isoforms which are essential for cellular adhesion and signaling.
Biological function summary

LAMA3 plays an important role in the formation of stable basement membranes and interacts with other proteins to maintain tissue architecture. As part of the laminin-332 complex alongside beta and gamma laminin chains LAMA3 ensures cell adhesion migration and differentiation processes. Its expression in tissues like skin and mucosal surfaces highlights its function in providing structural support and cellular microenvironment regulation.

Pathways

Laminin subunit alpha-3 is essential in pathways related to cell adhesion and migration such as integrin signaling and epithelial-mesenchymal transition. These pathways are pivotal during wound healing and tissue regeneration. LAMA3 associates with integrins particularly beta-1 and beta-4 integrins facilitating communication between cells and their extracellular environment. The interaction with integrins enables cells to respond to structural changes and external stimuli.

Mutations or alterations in LAMA3 can lead to conditions such as Epidermolysis Bullosa and Junctional Epidermolysis Bullosa where the integrity of the skin and epithelial tissues is compromised. Laminin subunit gamma-2 often interacts with LAMA3 and anomalies in this partnership contribute to these severe blistering disorders. Understanding the link between LAMA3 and these diseases helps inform the development of targeted therapies aimed at restoring normal cell-matrix interactions.

Target data

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.. Laminin-5 is thought to be involved in (1) cell adhesion via integrin alpha-3/beta-1 in focal adhesion and integrin alpha-6/beta-4 in hemidesmosomes, (2) signal transduction via tyrosine phosphorylation of pp125-FAK and p80, (3) differentiation of keratinocytes.
