Summary: A structural constituent of eye lens. Involved in intermediate filament organization. Acts upstream of or within cell maturation and lens fiber cell development. Located in cytoplasm; intermediate filament; and plasma membrane. Is expressed in several structures, including eye and male reproductive gland or organ.

CP49 and filensin intermediate filaments are essential for formation of cold cataract.
Title: CP49 and filensin intermediate filaments are essential for formation of cold cataract.
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.

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.
