Accumulation of beta ig-h3 gene product in corneas with granular dystrophy.

We isolated and identified the major protein present in corneas with granular dystrophy ( GCD). We compared Coomassie-blue-stained protein bands obtained on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) from the extracts of corneas with GCD, corneas with other disorders, and normal human corneal tissue. After SDS-PAGE and transfer to a polyvinylidene difluoride membrane, bands of interest were analyzed by amino acid sequencing and by Western blotting. Corneas with GCD were also examined immunohistochemically. On SDS-PAGE a 63-kd band just below albumin was present in extracts of all corneas. The albumin/63-kd ratio was normally approximately 3:1, suggesting that the protein is a dominant constituent of the cornea. This band was much more plentiful than normal in corneas with GCD. Amino-terminal sequence analysis of the protein revealed a Gly-Pro-Ala-Lys-Ser-Pro-Tyr-Gln-Leu-Val-Leu-Gln-His-Ser-Arg sequence indistinguishable from an amino-terminal protein sequence deduced from a cDNA clone designated beta ig-h3, and it as well as the abnormal accumulations in GCD cross-reacted with beta ig-h3 antiserum. The presence of excessive beta ig-h3 in human corneas with GCD together with reported mutations in the beta ig-h3 gene in GCD suggests that the mutated gene product is a fundamental constituent of the characteristic corneal accumulations in GCD.[1]
