LAMB4 (Laminin Subunit Beta 4) is a Protein Coding gene. Diseases associated with LAMB4 include Diverticulitis. Among its related pathways are Focal Adhesion and Phospholipase-C Pathway. An important paralog of this gene is LAMB1. 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.
