Summary: Predicted to enable enzyme binding activity; glycosphingolipid binding activity; and integrin binding activity. Predicted to be a structural constituent of synapse-associated extracellular matrix. Predicted to be an extracellular matrix structural constituent. Predicted to be involved in several processes, including basement membrane assembly; neurogenesis; and substrate adhesion-dependent cell spreading. Predicted to act upstream of or within embryo implantation and neuron projection development. Located in collagen-containing extracellular matrix.

What's a GeneRIF?

Knockdown of endogenous laminin-B1 expression using RNA interference (LB1 siRNA) enhanced water maze performance.
Title: Laminin-β1 impairs spatial learning through inhibition of ERK/MAPK and SGK1 signaling.
Binding sites for alpha3beta1 and alpha6beta4 are closely spaced in the Ln-332 LG domains where they regulate alternative cell functions, namely adhesion/migration or hemidesmosome anchoring.
Title: Epitope mapping of function-blocking monoclonal antibody CM6 suggests a "weak" integrin binding site on the laminin-332 LG2 domain.
Manifestation of laminin immunoreactivity indicates gliovascular decoupling afgter traumatic brain injury.
Title: Post traumatic lesion absence of beta-dystroglycan-immunopositivity in brain vessels coincides with the glial reaction and the immunoreactivity of vascular laminin.

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.
