Summary: Enables glycosphingolipid binding activity. An extracellular matrix structural constituent. Involved in protein phosphorylation. Acts upstream of or within several processes, including morphogenesis of an epithelium; neuron projection development; and retinal blood vessel morphogenesis. Located in basement membrane and cell-cell junction. Part of laminin-1 complex. Is expressed in several structures, including alimentary system; early conceptus; eye; genitourinary system; and nervous system. Orthologous to human LAMA1 (laminin subunit alpha 1).

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.
