Summaries for LAMA2 Gene

Entrez Gene Summary for LAMA2 Gene

  • Laminin, an extracellular protein, is a major component of the basement membrane. It is thought to mediate the attachment, migration, and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. It is composed of three subunits, alpha, beta, and gamma, which are bound to each other by disulfide bonds into a cross-shaped molecule. This gene encodes the alpha 2 chain, which constitutes one of the subunits of laminin 2 (merosin) and laminin 4 (s-merosin). Mutations in this gene have been identified as the cause of congenital merosin-deficient muscular dystrophy. Two transcript variants encoding different proteins have been found for this gene.

GeneCards Summary for LAMA2 Gene

LAMA2 (Laminin, Alpha 2) is a Protein Coding gene. Diseases associated with LAMA2 include muscular dystrophy, congenital merosin-deficient and lama2-related muscular dystrophy. Among its related pathways are PI3K-Akt signaling pathway and Pathways in cancer. GO annotations related to this gene include receptor binding and structural molecule activity. An important paralog of this gene is LAMC2.

Alpha-2 is a subunit of laminin-2 (laminin-211 or merosin), laminin-4 (laminin-221 or S-merosin) and laminin-12 (laminin-213). Interacts with FBLN1, FBLN2 and NID2
