Characterisation of the Start repressor Whi7

Our group has characterised a new important regulator of the Start transition: Whi7. Whi7 acts as a transcriptional repressor of the Start programme, collaborating with Whi5 in this function, so that, as occurs in mammals with the Rb family, the control of cell cycle initiation depends on the interplay between different repressors. The group's work aims to advance in the characterisation of the regulation and function of Whi7 and its comparison with Whi5 in different physiological conditions, which may help to understand how the action of different repressors is coordinated in the control of cell cycle initiation. In addition, the relationship between Whi7 and the protein kinase C pathway is being investigated. The fact that a member of the Rb family is mutated in almost all tumours further reinforces the importance of studying the role of these G1 repressors.

Metabolic adaptations associated to the adaptation of lichen microalgae to extreme environmental conditions

Lichen microalgae play a very active role in the ability of lichens to survive in extreme environmental conditions. The aim of this line of work is to determine the metabolites involved in the adaptation of lichen microalgae to extreme conditions such as desiccation or cold in order to develop possible biotechnological applications for crops tolerance.

New mechanisms of control of other cell cycle regulators

The group's work also focuses on the study of spatial regulatory mechanisms in cell cycle control, mechanisms that involve the control of the sub-cellular localisation of key proteins for progression in the cycle. In particular, the role of karyopherin Msn5 in the control of transcription factors (Swi6, Swi4, Mbp1, Swi1, Whi5) as well as Start cyclins (Cln1, Cln2) has been studied. Furthermore, determinants of cyclin functional specificity and the identification of new mechanisms controlling cyclin synthesis and degradation (Cln2, Clb2) are investigated.

Study of the control of translation by the evolutionarily conserved factor eIF5A and its role in pathologies

eIF5A is an elongation factor that binds to ribosomes when they get stuck during the synthesis of some proteins containing proline, glycine and charged amino acid motifs. Our group has determined that eIF5A is required for the synthesis of formins (yeast, fly and mouse), collagen (mouse and human) and human proteins that are prone to aggregation in aged cells. Our aim is to mechanistically determine the function of eIF5A, through the synthesis of its target proteins, in pathologies such as fibrosis, cancer or during ageing. Understanding these mechanisms will help in the development of specific therapies aimed at regulating eIF5A function.
