Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER
Sammanfattning : Membrane proteins are found in all kingdoms of life and are essential for cellular interactions with the environment. Although a large research effort have been put into this group many membrane proteins remains uncharacterized, both in terms of function and evolutionary history. LÄS MER
3. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening
Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER
Sammanfattning : Alpha-helical transmembrane proteins are important components of many essential cell processes including signal transduction, transport of molecules across membranes, protein and membrane trafficking, and structural and adhesion activities, amongst others. Their involvement in critical networks makes them the focus of interest in investigating disease pathways, as candidate drug targets, and in evolutionary analyses to identify homologous protein families and possible functional activities.

Sammanfattning : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.
