Summaries for LAMA1 Gene

Entrez Gene Summary for LAMA1 Gene

  • This gene encodes one of the alpha 1 subunits of laminin. The laminins are a family of extracellular matrix glycoproteins that have a heterotrimeric structure consisting of an alpha, beta and gamma chain. These proteins make up a major component of the basement membrane and have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Mutations in this gene may be associated with Poretti-Boltshauser syndrome. [provided by RefSeq, Sep 2014]

GeneCards Summary for LAMA1 Gene

LAMA1 (Laminin Subunit Alpha 1) is a Protein Coding gene. Diseases associated with LAMA1 include Poretti-Boltshauser Syndrome and Degenerative Myopia. Among its related pathways are Phospholipase-C Pathway and Syndecan-4-mediated signaling events. GO annotations related to this gene include receptor binding and glycosphingolipid binding. An important paralog of this gene is LAMA2.

UniProtKB/Swiss-Prot for LAMA1 Gene

  • 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.

    • Laminin is a complex glycoprotein, consisting of three different polypeptide chains (alpha, beta, gamma), which are bound to each other by disulfide bonds into a cross-shaped molecule comprising one long and three short arms with globules at each end. Alpha-1 is a subunit of laminin-1 (laminin-111 or EHS laminin) and laminin-3 (laminin-121 or S-laminin).
