Identification of mutation-prone points in bile salt export pump

(pro)renin receptor: A stable molecule

Background:

Basically, (pro)renin acts via a specific receptor, (pro)renin receptor (PRR) binding between renin and prorenin, its inactive proenzyme form. The study on the molecular level of PRR can give useful knowledge to help understand many renal disorders.

Method:

Here, the author focuses on the stability of the PRR molecule. The mutation prone positions within the PRR molecule was assessed using standard reference technique.

Result:

The study showed there is no identified mutation prone position within the PRR molecule.

Conclusion:

This imply the high stability of PRR. This means that PRR rarely undergoes mutation. The reported mutation in PRR should be a very rare episode and the study on the specific cause is warranted.

Mutation-prone positions within the estrogen receptor

OBJECTIVE

Estrogen is an important female hormone. The estrogen receptor (ER) plays a critical role in the development of breast cancer. Mutations within the ER can have clinically significant consequences.

MATERIALS AND METHODS

Identification of sites vulnerable to mutation is a new trend aimed at extending our knowledge of diseases at the genomic and proteomic levels. In this study, bioinformatics analysis was performed to determine the positions corresponding to specific peptide motifs in the amino acid sequence of the ER. A new computational tool called GlobPlot was used to identify the weak linkage positions within the ER.

RESULTS

The results allowed the identification of mutation-resistant positions.

CONCLUSION

This study showed that the weak linkages within the ER could be identified, and these could provide the basis for further studies aimed at predicting possible new ER mutations.
