Title:

Structure of the human MLH1 N-terminus: implications for predisposition to Lynch syndrome.

Journal:

Acta Crystallogr F Struct Biol Commun. 2015 Aug;71(Pt 8):981-5. doi:, 10.1107/S2053230X15010183. Epub 2015 Jul 28.

Abstract:

Mismatch repair prevents the accumulation of erroneous insertions/deletions and non-Watson-Crick base pairs in the genome. Pathogenic mutations in the MLH1 gene are associated with a predisposition to Lynch and Turcot's syndromes. Although genetic testing for these mutations is available, robust classification of variants requires strong clinical and functional support. Here, the first structure of the N-terminus of human MLH1, determined by X-ray crystallography, is described. The structure shares a high degree of similarity with previously determined prokaryotic MLH1 homologs; however, this structure affords a more accurate platform for the classification of MLH1 variants.
