Transducer Mechanism: G Protein–Coupled Receptors

Transducer Mechanism: G Protein–Coupled Receptors

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical,...

Translation

Translation

Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
Translation Produces the Building Blocks of...

Transformers

Transformers

A device that transforms voltages from one value to another using induction is called a transformer. A transformer consists of two separate coils, or windings, wrapped around the same soft iron core. However, they are electrically insulated from each other.
The iron core has a substantial relative permeability. Therefore, the magnetic field lines generated due to the current in one winding are almost entirely confined within the core, such that the same magnetic flux permeates each turn of both...

In Vitro Fertilization

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Contact-dependent Signaling

Contact-dependent Signaling

Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
Gap Junctions
In animal cells, gap junctions are formed...

G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Background:

The Gesneriaceae family, particularly the Primulana genus, is known for its diverse species found in karst regions.
Accurate taxonomic descriptions and phylogenetic analyses are crucial for understanding plant diversity and conservation.

Purpose of the Study:

To describe and illustrate a new species of Primulana discovered in Guangdong, China.
To differentiate the new species from morphologically similar taxa using detailed morphological and phylogenetic analyses.
To assess the conservation status of the newly described species.

Main Methods:

Morphological comparisons with related species, including detailed examination of leaves, bracts, calyx lobes, stamens, and pistils.
Phylogenetic analyses using internal transcribed spacer (ITS) and trnL-F sequences.

Application of the IUCN Red List Criteria for conservation status assessment.

Main Results:

*Primulinananlingensis* sp. nov. is described, distinguished by larger crenate-margined leaves, fewer flowers per cyme, ovate-lanceolate bracts, specific calyx lobe dentation, and glandular stamens and pistil.
Phylogenetic analyses place *P. nanlingensis* as sister to *P. versicolor* and *P. pengii*, confirming its distinctness from morphological relatives.
The new species is assessed as Near Threatened (NT) based on IUCN Red List Criteria.

Conclusions:

*Primulinananlingensis* represents a new addition to the Gesneriaceae family, endemic to the Karst region of Guangdong, China.
Distinct morphological and phylogenetic characteristics support its status as a new species.
The Near Threatened status highlights the need for conservation efforts for this newly discovered plant.
