Summary
Ferlin proteins regulate calcium-triggered membrane events and interact with calcium channels, distinguishing them from synaptotagmin proteins. These findings clarify ferlins
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- Ferlin family proteins are multi-C2 domain regulators involved in membrane fusion and fission.
- Ferlins share initial similarities with synaptotagmin calcium sensors.
- Recent studies reveal distinct functions of ferlins compared to synaptotagmin.
Purpose of the Study:
- To highlight recent findings on ferlin proteins.
- To elucidate the functional differences between ferlins and synaptotagmin proteins.
- To understand ferlins' roles in membrane trafficking and calcium channel interaction.
Main Methods:
- Review of recent scientific literature.
- Comparative analysis of ferlin and synaptotagmin protein functions.
- Focus on protein-protein interactions and cellular processes.
Main Results:
- Ferlins interact directly with non-neuronal voltage-gated calcium channels.
- Ferlins nucleate the assembly of membrane-trafficking protein complexes.
- These functions differentiate ferlins from synaptotagmin family members.
Conclusions:
- Ferlins possess unique functions beyond calcium sensing.
- Ferlins play a distinct role in regulating membrane dynamics and trafficking.
- Understanding ferlins' specific roles is crucial for cell biology research.

01:25Structure of Cadherins
5.0K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

6.8K
Myosins are a family of molecular motor proteins, first identified in the skeletal muscles, where they are responsible for muscle contraction. Along with their role in muscle contraction, these proteins also play a role in the intracellular transport of molecules and vesicles. There are twenty-four classes of myosins based on their domain sequence and organization. Of the twenty-four, six classes (Myosin I, Myosin II, Myosin V, Myosin VI, Myosin VII, and Myosin X) have been well...

01:43SNAREs and Membrane Fusion
13.0K
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...

6.7K
Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

4.3K
Bacterial cells were initially considered simple, randomly organized structures lacking a cytoskeleton. However, the discovery of cytoskeleton homologs in bacteria led to the change of this opinion. Bacterial cytoskeletal filaments regulate the cell shape, cell polarity, cell division, and partitioning of plasmids during cell division. It was later discovered that bacterial cytoskeletal proteins, mainly actin and tubulin homologs, are diverse compared to their eukaryotic counterparts. On the...

01:14Generation of Straight or Branched Actin Filaments
3.9K
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...
