Al as well because the exposure of nonpolar groups may have an effect on its association with other protein molecules and decrease its solubility. The mutation Y134A is situated inside the middle strand of your 4th motif, and though it does not disrupt the topology, it does expose asmany as 5 apolar and 13 polar side chains, which would lead to decreased solubility and possible aggregation. Inside the mutant R140X, we note that a substantial fraction in the area contributing to the C-terminal domain is lost upon truncation. The deleted region incorporates three b-strands which form an integral a part of the jellyroll fold in the C-terminal domain. Loss of three b-strands and five buried apolar residues in the deleted region is expected to lead to the close to total loss of structure of your C-terminal domain. Considerable loss of tertiary structure, higher exposure of nonpolar residues and of Cys 109 could be expected to lead to aggregation of your molecule. With all the other truncation mutant W157X too, the circumstance is fairly the exact same, as seen in Figure 5, and in Table 1. We think this would also be the case with all the other mutant, Y134X, reported to take place within a Danish infant with congenital cataract-microcornea syndrome; in comparison to R140X, this mutant has lost the hexapeptide sequence ELSNYR, comprising just about all surface-seeking residues. The situation with Y56X, which has lost even greater part of the chain, is expected to become far more serious (see Table S1 in File S1 for phenotypic particulars of these mutations). The frameshift mutation in G165fs final results in premature termination, resulting within the loss of a C-terminal b-strand. The exposure of Cys 109 and of many nonpolar residues together with the loss of tertiary contacts as a consequence of the missing b-strand would influence the stability from the molecule.Other Members on the c-crystallin FamilyWhile we’ve described our analysis of mutations in HGDC so far, we locate it interesting to note that the reported mutations in other human c-crystallins (cC, cS) and even b-crystallins display a similar phenotypic dichotomy.
