Gene Gene information from NCBI Gene database.
Entrez ID 3914
Gene name Laminin subunit beta 3
Gene symbol LAMB3
Synonyms (NCBI Gene)
AI1ABM600-125KDAJEB1AJEB1BLAM5LAMNB1
Chromosome 1
Chromosome location 1q32.2
Summary The product encoded by this gene is a laminin that belongs to a family of basement membrane proteins. This protein is a beta subunit laminin, which together with an alpha and a gamma subunit, forms laminin-5. Mutations in this gene cause epidermolysis bul

Protein name Laminin subunit beta-3 (Epiligrin subunit bata) (Kalinin B1 chain) (Kalinin subunit beta) (Laminin B1k chain) (Laminin-5 subunit beta) (Nicein subunit beta)
Protein function 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.
