Summary: Predicted to enable glycosphingolipid binding activity. Predicted to be an extracellular matrix structural constituent. Predicted to be involved in several processes, including axon guidance; blood vessel morphogenesis; and protein phosphorylation. Predicted to act upstream of or within several processes, including morphogenesis of an epithelium; neuron projection development; and retinal blood vessel morphogenesis. Predicted to be located in several cellular components, including cell-cell junction; extracellular matrix; and extracellular space. Predicted to be part of laminin-1 complex and laminin-3 complex. Predicted to be active in basement membrane. Orthologous to human LAMA1 (laminin subunit alpha 1). [provided by Alliance of Genome Resources, Nov 2024]

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.
