Laminin subunit alpha-1 (LAMA1)

Laminin subunit alpha-1 is a large extracellular matrix glycoprotein that, along with beta and gamma chains, forms heterotrimeric laminin molecules essential for the structure and function of basement membranes in nearly all animal tissues. The laminin alpha-1 chain is crucial for organizing cell layers, mediating cell adhesion, migration, tissue development, and maintenance of extracellular matrix architecture. Mutations in *LAMA1* are linked to Poretti–Boltshauser syndrome, a rare developmental disorder. Laminins interact with high-affinity cell-surface receptors mediating tissue-specific functions and cellular behaviors, but are not classical drug targets[1][2][3][4][5][6][7].
