Summary: Enables integrin binding activity. Involved in several processes, including cell-cell adhesion mediated by integrin; pilomotor reflex; and positive regulation of ERK1 and ERK2 cascade. Acts upstream of or within several processes, including branching involved in ureteric bud morphogenesis; positive regulation of cell-substrate adhesion; and positive regulation of transforming growth factor beta receptor signaling pathway. Located in basement membrane; extracellular region; and smooth muscle contractile fiber. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Used to study bilateral renal aplasia. Orthologous to human NPNT (nephronectin). [provided by Alliance of Genome Resources, Dec 2024]

Nephronectin is produced by podocytes and deposited into the GBM. It colocalized with alpha8beta1 integrin to novel, specialized adhesion structures at sites of mesangial cell protrusion at the base of the capillary loops. Nephronectin loss disrupted these structures, mislocalizating alpha8beta1, and caused mesangial sclerosis.

Results show that Npnt is highly expressed in tooth germ, and localized in the basement membrane between dental epithelium and mesenchyme. The study indicates that Npnt plays a critical scaffold role in dental epithelial stem cell differentiation and proliferation, and regulates Sox2 expression during tooth development.

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.
