Overview

The reduction in chromosome number during meiosis is essential for the production of haploid germ cells that produce healthy offspring upon fertilisation. This is achieved through an elaborate cellular process of chromosome ‘choreography’ during meiotic prophase, in which errors lead to infertility, miscarriage and genetic disorders such as Down’s syndrome. Rapid chromosomal movements enable the identification and synapsis of homologous chromosome pairs. Once achieved, homologues exchange genetic material through crossing over and are then moved into position at metaphase to enable their correct segregation into haploid cells. This intricate process depends upon chromosome telomeric ends being tethered to the nuclear envelope by the meiotic-telomere complex (MAJIN, TERB1, TERB2, TRF1) and connected to the cytoskeleton by the LINC complex (SUN1, KASH5). However, whilst essential for meiosis, we currently lack essential molecular understanding regarding their structure and function.

This PhD project aims to elucidate the molecular structure of the meiotic-telomere and LINC complexes, and their mechanisms of interaction with telomeres and the cytoskeleton. It will involve recombinant protein purification, biochemistry, biophysics (including SEC-MALS, SEC-SAXS, CD and EM) and X-ray crystallography. This project is part of an international collaboration with EM tomography, genetics and cellular biology groups, and will likely result in high impact research findings in the fields of cell division and chromosomal biology. The successful candidate will be a highly-motivated individual with interests in solving fundamental molecular questions of cellular function through structural biology.
