LAMB3 encodes the beta 3 subunit of laminin. Laminin is composed of three subunits (alpha, beta, and gamma), and refers to a family of basement membrane proteins. For example, LAMB3 serves as the beta chain in laminin-5. Mutations in LAMB3 have been identified as the cause of various types of epidermolysis bullosa. Two alternatively spliced transcript variants encoding the same protein have been found for this gene.^[7]
