Job description

Offer DescriptionPrimary ciliary dyskinesia (PCD), with main symptoms of recurrent respiratory infections, male infertility and body symmetry disorders, belongs to a class of inherited diseases known as ciliopathies. In the case of PCD, the disease is related to the disruption of the function of motile cilia – projections extending from the surface of respiratory epithelium cells, as well as sperm and the embryonal node. PCD is a highly heterogeneous disease (over 50 genes published so far). It is caused by recessive mutations in genes encoding proteins that either form structural/functional elements of motile cilia or are necessary during their biogenesis. PCD is most often caused by defects in the outer dynein arms (ODA), elements of the motile structure of the cilium responsible for generating their movement. To become functional components of the cilium, numerous ODA proteins are preassembled in the cytoplasm with the help of other proteins. Most pathogenic mutations in PCD patients result in the absence of full-length ciliary proteins. Missense mutations, resulting in amino acid (aa) substitutions, are less common. The mechanisms by which such mutations disrupt ODA assembly, structure, and function in ciliated epithelial cells are poorly understood. DNAI1, a dynein intermediate chain protein, is part of ODA and one of two proteins that initiate the process of ODA initial assembly in the cytoplasm. DNAI1 is one of the eight PCD genes in which mutations are most frequently detected in Polish PCD patients. Among pathogenic DNAI1 variants, aa substitutions are more common than in most other PCD genes. Most of the pathogenic aa substitutions in DNAI1 resulting in lack of ODA occur in exons that encode the important WDR40 domain, known for its function in protein binding. In the project, we will investigate how aa substitutions in the DNAI1 protein impair its structure, stability and/or protein-protein interactions important for proper initial assembly and functioning of ODA, ultimately leading to changes in structure and defects in ciliary motility. Project stages: 1. In silico prediction of the impact of aa DNAI1 substitutions detected in PCD patients on the structure and stability of the WDR domain. 2. Biophysical analyzes of isolated DNAI1 protein variants to verify in silico models. 3. Effect of aa substitution in DNAI1 on its binding with the known interactor, DNAI2. 4. Effect of amino acid substitution in DNAI1 on the functioning of respiratory epithelial cells. 5. The effect of DNAI1 amino acid substitution on its interactions with other proteins in epithelial cells. The PhD student will be involved in stages 3,4,5.Keywords:motile cilia, amino acid variants, WDR domains, protein interactions, respiratory epithelium cell culturesPredicted tasks in the project:

• active participation in the implementation of the experimental tasks of the grant and the analysis of results using modern techniques (CRISPR, protein expression in mammalian cells, biophysical analyzes of the structure of molecular proteins)• presenting at seminars and conferences, and participation in writing scientific publications• supervision of students
