Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.6K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Vesicular Tubular Clusters01:45

Vesicular Tubular Clusters

2.6K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
With the help of motor proteins such...

Protein Translocation Machinery on the ER Membrane01:28

Protein Translocation Machinery on the ER Membrane

4.8K
The translocon complex situated on the ER membrane is the main gateway for the protein secretory pathway. It facilitates the transport of nascent peptides into the ER lumen and their insertion into the ER membrane.
Sec61 protein conducting channel
In eukaryotes, the translocon complex comprises a core heterotrimeric translocator channel called the Sec61 complex. This channel includes three transmembrane proteins, Sec61α, Sec61β, and Sec61γ, and is the largest subunit of the...

Protein Complex Assembly02:41

Protein Complex Assembly

10.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

5.8K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Cotranslational Protein Translocation01:20

Cotranslational Protein Translocation

7.5K
Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.
Sec61 channel partners for cotranslational translocation
During cotranslational translocation, the Sec61 channel partners with the signal recognition particle (SRP), the signal recognition particle receptor (SR), and the ribosomes to transport the nascent polypeptide chain...

Area of Science:

  • Ion channel biophysics
  • Cellular biology
  • Molecular medicine

Background:

  • Polycystin subunits form hetero- and homotetrameric ion channels in various cellular compartments.
  • Homotetrameric channels are voltage- and calcium-modulated; heterotetrameric channels are proposed to be ligand- or autoproteolytically regulated.
  • Polycystin variants are linked to autosomal dominant polycystic kidney disease and play vital roles in fertilization and embryonic development.

Purpose of the Study:

  • To review recent structural and functional characterization of polycystin channels.
  • To provide a molecular blueprint for investigating channel gating mechanisms.
  • To discuss the diverse sensory functions and tissue-specific physiological impacts of polycystin channels.

Main Methods:

  • Review of recent structural and functional studies.
  • Analysis of polycystin channel assembly and subcellular distribution.
  • Individual consideration of polycystin channel types.

Main Results:

  • Structural and functional characterization provides a molecular blueprint for polycystin channels.
  • Diversity in assembly and distribution enables a multitude of sensory functions.
  • Polycystin channels contribute to sensory cell biology and tissue physiology.

Conclusions:

  • Understanding polycystin channel structure and function is key to investigating their roles in health and disease.
  • The diverse nature of polycystin channels underlies their broad physiological importance.
  • Further research into conformational changes will illuminate stimulus-response mechanisms.
