Summary: Predicted to enable integrin binding activity. Predicted to be a structural constituent of synapse-associated extracellular matrix. Predicted to be involved in several processes, including axon guidance; basement membrane assembly; and substrate adhesion-dependent cell spreading. Predicted to act upstream of or within several processes, including metanephric glomerulus development; neurogenesis; and visual perception. Predicted to be located in basement membrane and synapse. Predicted to be part of laminin-3 complex. Predicted to be active in neuromuscular junction and synaptic cleft. Used to study proteinuria. Human ortholog(s) of this gene implicated in Pierson syndrome; nephrotic syndrome type 5; and primary open angle glaucoma. Orthologous to human LAMB2 (laminin subunit beta 2).

Crystallographic analysis of the LAMB2 short arm reveals how the LF domain is inserted into a regular array of LE domains.
Title: Crystallographic analysis of the laminin β2 short arm reveals how the LF domain is inserted into a regular array of LE domains.
Together, these studies provide evidence for regulation of Lamb2 translation by IMP2, an RNA binding protein that targets Lamb2 mRNA to the actin cytoskeleton.
Title: RNA-binding protein IGF2BP2/IMP2 is required for laminin-β2 mRNA translation and is modulated by glucose concentration.
R246Q mutation causes nephrotic syndrome by impairing secretion of laminin-521 from podocytes into the glomerular basement membrane (GBM).
Title: A missense LAMB2 mutation causes congenital nephrotic syndrome by impairing laminin secretion.
Chronic exposure to high glucose leads to impaired mesangial cell migration in response to IGFBP-5 as a result of loss of laminin beta2 protein.
Title: Reductions in laminin beta2 mRNA translation are responsible for impaired IGFBP-5-mediated mesangial cell migration in the presence of high glucose.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
