Summary: Enables hormone activity. Involved in several processes, including bone trabecula formation; positive regulation of osteoblast differentiation; and sequestering of TGFbeta in extracellular matrix. Acts upstream of or within embryonic limb morphogenesis. Located in extracellular region and microfibril. Is expressed in several structures, including eye; heart; mesonephros; respiratory system; and urinary system. Used to study distal arthrogryposis. Human ortholog(s) of this gene implicated in congenital contractural arachnodactyly and scoliosis. Orthologous to human FBN2 (fibrillin 2). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in limb E14.5 (RPKM 40.9), CNS E11.5 (RPKM 13.1) and 5 other tissues See more

Title: Fibrillin-2 is a key mediator of smooth muscle extracellular matrix homeostasis during mouse tracheal tubulogenesis.
Downstream target genes of Ucma were found in osteoblasts by microarray analysis. 45 genes including Fbn2 were dependent on Ucma overexpression or knockdown. Fbn2 expression was proportional to Ucma expression in osteoblasts.

The analysis of Adamts10-/- mice led to identification of Fbn2 as a novel ADAMTS10 substrate and defined a proteolytic mechanism for clearance of ocular Fbn2 at the end of the juvenile period.
Title: Adamts10 inactivation in mice leads to persistence of ocular microfibrils subsequent to reduced fibrillin-2 cleavage.
Studies provide evidence for the unique role of fibrillin-2 in regulating BMP-dependent limb patterning and its distinct impact from fbn1 proteins on the commitment and differentiation of marrow mesenchymal stem cells. [review]

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.
