Lipid Rafts : Keys to Sperm Maturation, Fertilization, and Early Embryogenesis

Abstract EN

Cell membranes are composed of many different lipids and protein receptors, which are important for regulating intracellular functions and cell signaling.

To orchestrate these activities, the cell membrane is compartmentalized into microdomains that are stably or transiently formed.

These compartments are called “lipid rafts”.

In gamete cells that lack gene transcription, distribution of lipids and proteins on these lipid rafts is focused during changes in their structure and functions such as starting flagella movement and membrane fusion.

In this paper, we describe the role of lipid rafts in gamete maturation, fertilization, and early embryogenesis.
