    Summary
    A structural constituent of eye lens. Involved in intermediate filament organization. Acts upstream of or within cell maturation; intermediate filament cytoskeleton organization; and lens fiber cell development. Located in cytoplasm and intermediate filament. Is expressed in lens; olfactory epithelium; and vomeronasal organ. Human ortholog(s) of this gene implicated in cataract and cataract 12 multiple types. Orthologous to human BFSP2 (beaded filament structural protein 2). [provided by Alliance of Genome Resources, Apr 2022]

    2. CP49 and filensin have been considered robust markers for mouse lens fiber cell differentiation. The data reported here, however, document both proteins in the mouse lens epithelium, but only after 5 weeks of age, when lens epithelial growth and mitotic activity have slowed.

    4. disruption of the Hsf4 gene leads to cataracts via at least three pathways: down-regulation of gamma-crystallin, particularly gamma S-crystallin; decreased lens beaded filament expression; and loss of post-translational modification of alpha A-crystallin

    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.
