Fibulin 2 localized to the RPE, choroid, and Bruch's membrane. Knockout mice had a significantly reduced scotopic A response by 1 month of age, when compared to their wild-type counterparts, which remained throughout life and only declined as a result of normal aging. The functional decline was associated with reduced number of photoreceptor cells.

Our study indicates that Ang II cannot induce TGF-beta activation without fibulin-2 and that fibulin-2 has an essential role in Ang II-induced TGF-beta signaling and subsequent myocardial fibrosis. Fibulin-2 can be considered as a critical regulator of TGF-beta that induces myocardial fibrosis.

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.
