Summary: Predicted to enable metal ion binding activity. Involved in eye development. Acts upstream of or within several processes, including embryonic digit morphogenesis; heart development; and inner ear development. Located in basement membrane. Is expressed in several structures, including alimentary system; central nervous system; integumental system; intraembryonic coelom; and sensory organ. Used to study Fraser syndrome and isolated cryptophthalmia. Human ortholog(s) of this gene implicated in Fraser syndrome 2 and isolated cryptophthalmia. Orthologous to human FREM2 (FRAS1 related extracellular matrix 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Report Fras1 up-regulation/Frem down-regulation in nephrons from mice with polycystic kidney disease and Frem2 mutations.
Title: Expression of Fraser syndrome genes in normal and polycystic murine kidneys.
The QBRICK, together with Frem2, defines the ability of BMs to bind integrin 81 through modulating the BM assembly of nephronectin, thereby regulating the integrin 81-mediated signals transmitted from the ureteric buds to the metanephric mesenchyme.
Title: Basement membrane assembly of the integrin α8β1 ligand nephronectin requires Fraser syndrome-associated proteins.
The localization pattern of Fras1 and Frem2 was indistinguishable, while both proteins along with Frem3 could be detected even in the absence of Frem1.
Title: Differential localization profile of Fras1/Frem proteins in epithelial basement membranes of newborn and adult mice.
Fras1 is not only essential as a component of a macromolecular complex for the extracellular stabilization of Frem2 but it is also required for its proper intracellular trafficking and export from embryonic epithelial cells.
Title: Basement membrane localization of Frem3 is independent of the Fras1/Frem1/Frem2 protein complex within the sublamina densa.
expression of Frem2 may dynamically alter the extracellular matrix to provide a substrate for cell migration and rearrangements during embryogenesis
Title: Tissue morphogenesis and vascular stability require the Frem2 protein, product of the mouse myelencephalic blebs gene.
Study reports a comparative analysis of the spatiotemporal localization of Fras1, Frem1, Frem2 and Frem3 proteins during mouse embryonic development.
Title: Spatiotemporal distribution of Fras1/Frem proteins during mouse embryonic development.
QBRICK/Frem1, Fras1, and Frem2 interactions at the basement membrane have roles in preventing Fraser syndrome-like defects
Title: Breakdown of the reciprocal stabilization of QBRICK/Frem1, Fras1, and Frem2 at the basement membrane provokes Fraser syndrome-like defects.

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.
