Laminin, beta 3

Laminin subunit beta-3 is a is_associated_with::protein that in humans is encoded by the LAMB3 is_associated_with::gene.

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