Structural and functional characterization of D109H and R69C mutant versions of human αB-crystallin: The biochemical pathomechanism underlying cataract and myopathy development.

Abstract excerpt

In human αB-crystallin (αB-Cry), the highly conserved residues arginine 69 (R69) and aspartate 109 (D109) are located within a critical motif of α-crystallin domain (ACD), contributing to the subunit interactions and oligomeric assembly. Recently, two missense mutations (R69C and D109H) in human αB-Cry have been reported to cause congenital cataract and myopathy disorders. We used various spectroscopic...
