SEER Training: Cell Function

Cellular membranes are heterogeneous, and this has a great impact on cellular function. Despite the central role of membrane functions in multiple cellular processes in sperm, their molecular mechanisms are poorly understood. Membrane rafts are specific membrane domains enriched in cholesterol, ganglioside G M1 , and functional proteins, and they are involved in the regulation of a variety of cellular functions. Studies of the functional characterization of membrane rafts in mammalian sperm have demonstrated roles in sperm-egg binding and the acrosomal reaction. Recently, our biochemical and cell biological studies showed that membrane rafts are present and might play functional roles in chicken sperm. Biochemical comparison of the DRM between fresh and cryopreserved sperm demonstrated that cryopreservation induces cholesterol loss specifically from membrane rafts, indicating the functional connection with reduced post-thaw fertility in chicken sperm.

Structure and parts of a sperm cell

Researchers have found that a protein in the cell membranes of sperm plays a key role in how they find their way to eggs. The PMCA protein may also help explain how egg cells only interact with sperm from the same species. PMCA may even be a target of drug discovery. Sperm are excellent navigators. If they weren't we wouldn't even be here.

Ciliary and Flagellar Membranes pp Cite as. In this chapter the dynamics of molecular motions in the mammalian sperm plasma membrane will be discussed. Specifically, we will consider the nature of the known or potential forces which control these molecular motions. We will only discuss macromolecules that have been identified as having some physiological role and have been characterized on intact cells using biophysical techniques to gain insight into the organization of the sperm plasma membrane. Information on other cell-surface macromolecules, especially on cilia and flagella, is available in a number of articles e.
