Membrane-membrane and membrane-ligand interactions in Chlamydomonas mating
Society of General Physiologists Series
|January 1, 1980
Summary
Chlamydomonas mating involves flagellar tip adherence and signal transduction, leading to cell fusion. This rapid cellular response provides a model for studying membrane interactions.
Area of Science:
- Cell Biology
- Microbiology
- Biochemistry
Background:
- The mating reaction in Chlamydomonas is a complex cellular process.
- Cell-cell recognition and fusion are fundamental biological events.
Purpose of the Study:
- To investigate the intricate molecular events during Chlamydomonas mating.
- To understand the rapid cellular responses and signaling pathways involved in cell fusion.
Main Methods:
- Observation of mating events in Chlamydomonas.
- Utilizing the gam-1 mutation to study tipping inhibition.
- Investigating the effects of proteases and temperature on signal transduction.
Main Results:
- Mating involves flagellar tip adherence, reminiscent of lymphocyte capping.
- The gam-1 mutation and tubulin-interacting agents inhibit flagellar tipping.
- Signal transduction triggers cell wall shedding, mating structure activation, and cell fusion.
- Tip unlocking and activation reversal occur rapidly after zygote formation.
Conclusions:
- Chlamydomonas mating is a rapid, paradigm-setting process for studying membrane-membrane interactions.
- The study reveals key molecular players and sequential events in cellular conjugation.
- Further research is needed to elucidate the molecular mechanisms of tipping inhibition.

01:28Yeast Signaling
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
01:23Membrane Fluidity
Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.Fatty acids tails of phospholipids can be either saturated or...
01:43SNAREs and Membrane Fusion
Once a transport vesicle has recognized its target organelle, the vesicular membrane needs to fuse with the target membrane to unload the cargo. Transmembrane proteins called SNAREs present on organelle membranes and their vesicles, mediate vesicle fusion.
SNAREs exist in pairs that symmetrically interact and catalyze the fusion of the lipid bilayers in vesicle and target organelle. v-SNARE in the vesicle membrane are single polypeptide chains that bind to a complementary t-SNARE, composed of 2...

00:59Mechanisms of Membrane Domain Formation
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with cytoskeletal...

01:28Types of Membrane Protrusions
The protrusion of the cell surface is an initial step for several cellular processes, including cell migration, phagocytosis, and neurite outgrowth. These membrane protrusions are a result of cytoskeletal rearrangement. The most widely observed cell protrusions include lamellipodia, pseudopodia, filopodia, microvilli, invadopodia, and podosomes. These protrusions can be of two types — static or dynamic.
The microvilli, an example of stable protrusions, are finger-like projections with a...

01:14Cell Adhesion in Plants
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose, and...
