Summary
Rab23 protein regulates cell transport and the Sonic hedgehog (Shh) pathway. Its dysfunction is linked to neural tube defects and various cancers, highlighting its disease relevance.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- Rab23 is implicated in membrane trafficking and protein transport in eukaryotic cells.
- It acts as an indirect negative regulator of the Sonic hedgehog (Shh) signaling pathway.
- Rab23 dysfunction is associated with neural tube defects in mice and aberrant expression in human diseases, including various tumors.
Purpose of the Study:
- To review the known functions of Rab23.
- To summarize Rab23's involvement in genetic research, membrane trafficking, and autophagy.
- To focus on Rab23's role in tumor promotion, disease pathogenesis, and underlying regulatory mechanisms.
Main Methods:
- Literature review of existing studies on Rab23.
- Analysis of genetic research data related to Rab23.
- Examination of Rab23's role in cellular processes like membrane trafficking and autophagy.
Main Results:
- Rab23 plays a critical role in membrane trafficking and protein transport.
- It negatively regulates the Shh signaling pathway.
- Aberrant Rab23 expression is linked to neural tube defects and diverse human diseases, particularly cancers.
- Rab23 may also be involved in anti-infective autophagy.
Conclusions:
- Rab23 is a key regulator with diverse cellular functions.
- Its dysregulation contributes to significant human diseases, especially cancer.
- Further research into Rab23 mechanisms is warranted for therapeutic development.

Rab Proteins
5.3K
Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

Incomplete Dominance
31.6K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

The Retinoblastoma Gene
4.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Rab Cascades
3.7K
Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.

Exon Recombination
4.2K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...

Translation
21.1K
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.
