The LAMC2 protein also known as laminin subunit gamma-2 is an essential component of the extracellular matrix. It is a subunit of the laminin-332 complex formerly referred to as laminin-5 and has an approximate mass of 160 kDa. LAMC2 is widely expressed in various tissues most prominently in epithelial tissues. It localizes at the basement membrane zone where epithelial and mesenchymal tissues meet.

Biological function summary

LAMC2 plays a critical role in cell adhesion migration and signal transduction. Laminin-332 which includes LAMC2 binds to integrin receptors on cell surfaces facilitating cell-matrix interactions and communication. This complex is important for basement membrane stability and tissue organization and it is actively involved in wound healing by promoting keratinocyte migration and melanin transport.

Pathways

LAMC2 integrates into several important extracellular matrix pathways including the integrin signaling pathway. These pathways involve interactions with proteins like integrin alpha-6/beta-4 which are linked to cellular adhesion and mobility. LAMC2 also contributes to epithelial cell functions and is involved in the PI3K/AKT signaling pathway highlighting its importance in cell proliferation and survival.

LAMC2 has significant associations with conditions like dystrophic epidermolysis bullosa and invasive carcinomas. In dystrophic epidermolysis bullosa mutations in LAMC2 disrupt the integrity of the basement membrane leading to fragile skin and blistering. In cancer abnormal expression or alteration of LAMC2 can promote tumor invasion and metastasis often in conjunction with overexpression of matrix metalloproteinases (MMPs) that degrade the extracellular matrix therefore facilitating cancer cell infiltration.
