IFs help integrate individual cells into their respective tissues. This Review focuses on the lens-specific IF proteins beaded filament structural proteins 1 and 2 ([[BFSP1]] and [[BFSP2]]) and their role in lens physiology and disease. Evidence generated in studies in both mice and humans suggests a critical role for these proteins and their filamentous polymers in establishing the optical properties of the eye lens and in maintaining its transparency. For instance, mutations in both [[BFSP1]] and [[BFSP2]] cause cataract in humans. We also explore the potential role of [[BFSP1]] and [[BFSP2]] in aging processes in the lens.<br /> |mesh-terms=* Aging<br /> * Animals<br /> * Cataract<br /> * Eye Proteins<br /> * Humans<br /> * Intermediate Filament Proteins<br /> * Intermediate Filaments<br /> * Lens, Crystalline<br /> * Mice<br /> * Mutation<br /> * Vimentin<br /> * alpha-Crystallin B Chain<br /> <br /> |full-text-url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2701874<br /> }}<br /> {{medline-entry<br /> |title=The E233del mutation in [[BFSP2]] causes a progressive autosomal dominant congenital cataract in a Chinese family.<br /> |pubmed-url=https://pubmed.ncbi.nlm.nih.gov/17982427<br /> |abstract=Congenital cataract is a fundamental cause of blindness throughout the world. A large multi-generational family in northern China was investigated to determine the genetic cause of a progressive autosomal dominant congenital cataract. Slit-lamp photography was conducted to provide definite data for cataract diagnosis. A genome wide scan, linkage analysis, and haplotype analysis were performed to shield the linkage region on the chromosome. [[BFSP2]] was investigated by direct sequencing and detection of fluorescent labeled polymerase chain reaction (PCR) products. Two-point linkage analysis mapped this autosomal dominant congenital cataract (ADCC) locus to D3S1292 in 3q22.1 with a LOD score Zmax=3.99 (theta=0.00). Haplotype analysis located the cosegregating region between marker D3S1551 and D3S3617. In this region, [[BFSP2]] is a powerful candidate gene. Direct sequencing identified the cosegregating E233del mutation in exon 3 of [[BFSP2]]. This mutation was not detected in 100 unrelated controls. The E233del mutation in [[BFSP2]] is the cause of the cataract phenotype in this pedigree. The progressive phenotype has provided more evidence for the heterogeneity of congenital cataract caused by [[BFSP2]] mutations and for the important role [[BFSP2]] plays in cataract formation.<br /> |mesh-terms=* Aged<br /> * Aging<br /> * Asian Continental Ancestry Group<br /> * Cataract<br /> * Child<br /> * Chromosome Mapping<br /> * Chromosome Segregation<br /> * Chromosomes, Human, Pair 3<br /> * Disease Progression<br /> * Exons<br /> * Eye Proteins<br /> * Female<br /> * Gene Deletion<br /> * Genes, Dominant<br /> * Haplotypes<br /> * Humans<br /> * Intermediate Filament Proteins<br /> * Lod Score<br /> * Male<br /> * Pedigree<br /> <br /> <br /> }}</div>
