Protein Complex Assembly

Protein Complex Assembly

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...

Protein Complexes with Interchangeable Parts

Protein Complexes with Interchangeable Parts

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...

Formation of Complex Ions

Formation of Complex Ions

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Complex Power

Complex Power

Power engineers have introduced the concept of complex power to determine the cumulative effect of parallel loads. This idea plays a crucial role in power analysis because it encompasses all the details related to the power consumed by a specific load.
Complex power is defined as the multiplication of the voltage and the complex conjugate of the current. The magnitude of this power, known as apparent power, is measured in volt-amperes (VA). Notably, the angle of the complex power equates to the...

Complexation Equilibria: Factors Influencing Stability of Complexes

Complexation Equilibria: Factors Influencing Stability of Complexes

In complexation reactions, metal cations are the electron pair acceptors, and the ligands are the electron pair donors. The stability of the metal complexes depends primarily on the complexing ability of the central metal ion and the nature of the ligands. Generally, the complexing ability of the metal ion depends on the size and charge of the ion. As the metal ion size increases, the stability of the metal complexes decreases, provided that the valency of the metal ion and the ligands remain...

Crystal Field Theory - Octahedral Complexes

Crystal Field Theory - Octahedral Complexes

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Summary

Tuberous sclerosis complex (TSC) is a genetic disorder causing tumors. Targeting the mTORC1 pathway, particularly through skin lesions, offers diagnostic and therapeutic strategies for TSC symptoms.

Area of Science:

Genetics
Dermatology
Oncology

Background:

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by systemic hamartomas.
It results from mutations in TSC1 or TSC2 genes, leading to constitutive activation of mTORC1.
Dysfunctional hamartin-tuberin complex dysregulates mTORC1, causing various TSC symptoms.

Purpose of the Study:

To focus on the features of skin lesions in TSC.
To explore the role of skin lesions in differential diagnosis and therapy.
To discuss the therapeutic use of mTORC1 inhibitors for TSC.

Main Methods:

Review of TSC pathogenesis focusing on the mTORC1 pathway.
Analysis of clinical features of TSC, with emphasis on skin manifestations.

Evaluation of therapeutic strategies targeting mTORC1.

Main Results:

Constitutive mTORC1 activation is central to TSC pathogenesis.
Skin lesions are early, specific indicators of TSC, aiding diagnosis.
mTORC1 inhibitors demonstrate efficacy in treating TSC symptoms, including skin lesions.

Conclusions:

Skin lesions are crucial for early TSC diagnosis and monitoring.
Targeting the mTORC1 pathway with inhibitors is a promising therapeutic approach for TSC.
Further research into mTORC1 inhibitors can improve TSC management.
