Mutation effects on FAS1 domain 4 based on structure and solubility.

Biochim Biophys Acta Proteins Proteom 2022 03 20;1870(3):140746. Epub 2021 Dec 20.

Department of Chemistry, The Research Institute of Natural Sciences, Sookmyung Women's University, Cheongpa-ro 47-gil 100, Yongsan-gu, Seoul 04310, Republic of Korea. Electronic address:

Mutations in the fasciclin 1 domain 4 (FAS1-4) of transforming growth factor β-induced protein (TGFBIp) are associated with insoluble extracellular deposits and corneal dystrophies (CDs). The decrease in solubility upon mutation has been implicated in CD; however, the exact molecular mechanisms are not well understood. Here, we performed molecular dynamics simulations followed by solvation thermodynamic analyses of the FAS1-4 domain and its three mutants-R555W, R555Q, and A546T-linked to granular corneal dystrophy type 1, Thiel-Behnke corneal dystrophy and lattice corneal dystrophy, respectively.

A novel hotspot of gelsolin instability triggers an alternative mechanism of amyloid aggregation.

Comput Struct Biotechnol J 2021 19;19:6355-6365. Epub 2021 Nov 19.

Istituto di Biofisica, Consiglio Nazionale delle Ricerche, Milano, Italy.

Gelsolin comprises six homologous domains, named G1 to G6. Single point substitutions in this protein are responsible for AGel amyloidosis, a hereditary disease causing progressive corneal lattice dystrophy, cutis laxa, and polyneuropathy. Although several different amyloidogenic variants of gelsolin have been identified, only the most common mutants present in the G2 domain have been thoroughly characterized, leading to clarification of the functional mechanism.

JNMA J Nepal Med Assoc 2021 Apr 30;59(236):406-408. Epub 2021 Apr 30.

Tilganga Institute of Ophthalmology, Gaushala, Nepal.

Granular - lattice (Avellino) corneal dystrophy is inherited in an autosomal dominant fashion which affects stroma of the cornea with recurrent erosions and decreased vision due to clouding of cornea in later stage. We reported a case of 53-year old woman presented with pain and blurring of vision of left eye for 10 days with history of right eye deep anterior lamellar dystrophy and Left eye penetrating keratoplasty 5years back for Avellino dystrophy. On examination right eye graft was clear and left eye showed circular edges of irregular epithelium with patchy stains and epithelial defect suggestive of recurrence of dystrophy. Read More

Ocular Involvement in Hereditary Amyloidosis.

Genes (Basel) 2021 06 22;12(7). Epub 2021 Jun 22.

Amyloidosis Research and Treatment Centre, IRCCS Fondazione Policlinico San Matteo, 27100 Pavia, Italy.

The term amyloidosis describes a group of rare diseases caused by protein conformation abnormalities resulting in extracellular deposition and accumulation of insoluble fibrillar aggregates. So far, 36 amyloid precursor proteins have been identified, and each one is responsible for a specific disease entity. Transthyretin amyloidosis (ATTRv) is one of the most common forms of systemic and ocular amyloidosis, due to the deposition of transthyretin (TTR), which is a transport protein mainly synthesized in the liver but also in the retinal pigment epithelial cells.

Mutation-induced dimerization of transforming growth factor-β-induced protein may drive protein aggregation in granular corneal dystrophy.

J Biol Chem 2021 07 4;297(1):100858. Epub 2021 Jun 4.

Department of Molecular Biology and Genetics, Science Park, Aarhus University, Aarhus, Denmark. Electronic address:

Protein aggregation in the outermost layers of the cornea, which can lead to cloudy vision and in severe cases blindness, is linked to mutations in the extracellular matrix protein transforming growth factor-β-induced protein (TGFBIp). Among the most frequent pathogenic mutations are R124H and R555W, both associated with granular corneal dystrophy (GCD) characterized by the early-onset formation of amorphous aggregates. The molecular mechanisms of protein aggregation in GCD are largely unknown. Read More

Rapid, redox-mediated mechanical susceptibility of the cortical microtubule lattice in skeletal muscle.

Redox Biol 2020 10 18;37:101730. Epub 2020 Sep 18.

Department of Biochemistry, Molecular Biology and Biophysics, University of Minnesota, Minneapolis, MN, USA. Electronic address:

The highly ordered cortical microtubule lattice of skeletal muscle is disorganized in dystrophin-deficient mdx mice. Implicated mechanisms include loss of dystrophin binding, altered α-tubulin posttranslational modification, expression of a β-tubulin involved in regeneration, and reactive oxygen species (ROS). Here we show that the transverse microtubules in mdx muscle expressing miniaturized dystrophins are rapidly lost after eccentric contraction. Read More

Pharmaceutical modulation of the proteolytic profile of Transforming Growth Factor Beta induced protein (TGFBIp) offers a new avenue for treatment of -corneal dystrophy.

J Adv Res 2020 Jul 22;24:529-543. Epub 2020 May 22.

Singapore National Eye Centre, 11 Third Hospital Avenue, Singapore 168751, Singapore.

Corneal dystrophies are a group of genetically inherited disorders with mutations in the gene affecting the Bowman's membrane and the corneal stroma. The mutant TGFBIp is highly aggregation-prone and is deposited in the cornea. Depending on the type of mutation the protein deposits may vary (amyloid, amorphous powdery aggregate or a mixed form of both), making the cornea opaque and thereby decreases visual acuity.
