    APOBEC (Apolipoprotein B mRNA Editing Catalytic Polypeptide)

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: APOBEC

    Why in the News?

    Since smallpox was eradicated in 1980, research on mpox has highlighted how the virus mutates, particularly through the APOBEC family of immune system proteins.

    About APOBEC

    • APOBEC (Apolipoprotein B mRNA Editing Enzyme, Catalytic Polypeptide-Like) is a family of proteins involved in regulating the genetic material of viruses and cells.
    • They are part of the human immune system and play a crucial role in protecting against viral infections by editing RNA and DNA.
    • APOBEC consists of several enzymes, with APOBEC1, APOBEC3 family members being the most well-known.
    • There are 11 identified members of the APOBEC family, primarily named APOBEC1, APOBEC2, and APOBEC3, with APOBEC3 being the most studied due to its antiviral properties.
    • It has a Zinc Finger Domain, which is essential for their enzymatic activity and ability to bind to DNA or RNA.
    • APOBEC proteins are found in various tissues and cells, but they are notably present in the immune cells such as T-cells, B-cells, and macrophages.
    • Role in Immune Defense:
      • APOBEC proteins contribute to the innate immune response by editing viral genomes, preventing the replication of viruses, and reducing the ability of viruses to establish infections.
      • They are known to be cytosine deaminases, which means they modify cytosine bases in nucleic acids to uracil, leading to mutations that can prevent successful viral replication.
      • APOBEC proteins target the genomes of several viruses, including retroviruses (like HIV), hepatitis B virus, and poxviruses (such as mpox and smallpox).

    Functions of APOBEC Proteins:

    • DNA Editing: APOBEC proteins can deaminate cytosine bases in single-stranded DNA, converting them into uracil, which can lead to mutations.
      • This introduces errors in the viral genome and inhibits replication.
    • RNA Editing: Some APOBEC proteins, like APOBEC1, are involved in editing mRNA. In the case of APOBEC1, it helps edit the mRNA of apolipoprotein B, which is crucial for lipid metabolism.
    • Antiviral Activity: APOBEC3 proteins, particularly APOBEC3G, inhibit the replication of HIV and other retroviruses by editing viral DNA during reverse transcription.
      • They also reduce the replication of poxviruses (such as mpox), making them crucial in controlling infections caused by these viruses.
    • Cytosine Deamination in Viral RNA: APOBEC proteins induce mutations in viral RNA, reducing the virus’s ability to efficiently replicate and spread. This helps prevent viral evolution and adaptation.
    • Inhibition of Viral Resistance: By causing mutations in viral genomes, APOBEC proteins prevent viruses from easily developing resistance to the immune system’s defenses.
    • Interaction with Other Immune Mechanisms: APOBEC proteins work in concert with other immune mechanisms, like interferons, to enhance antiviral responses and limit infections.

    PYQ:

    [2016]  In the context of the developments in Bioinformatics, the term ‘transcriptome’, sometimes seen in the news, refers to:

    (a) a range of enzymes used in genome editing

    (b) the full range of mRNA molecules expressed by an organism

    (c) the description of the mechanism of gene expression

    (d) a mechanism of genetic mutations taking place in cells

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Airships

    How climate change is bringing back the idea of Airships?

    Why in the News?

    Some companies have been working to solve the buoyancy challenge of Airships, a longstanding issue that has hindered their use for cargo transportation.

    What are Airships?

    • Airships are lighter-than-air aircraft capable of controlled powered flight.
    • They were the first aircraft to achieve this and were considered the future of travel in the early 20th century.
    • However, as aeroplane technology advanced, the popularity of airships declined due to their technological limitations.
    • Today, airships are used mainly for:
      • Advertising platforms
      • Aerial observation for research and military purposes
      • Tourism and scenic flights
    Note: Buoyancy is the force that makes things float. It acts in the opposite direction to gravity. When an object is placed in a fluid (like air or water), the fluid pushes up against the object, helping it to stay afloat.

    How do Airships work?

    • Airships achieve lift by using lighter-than-air gases within their structure, much like helium balloons.
    • Early airships used hydrogen due to its lightweight and low cost.
      • However, hydrogen is highly flammable, leading to tragic incidents such as the Hindenburg disaster of 1937, which damaged public trust in airships.
    • Most airships today use helium, a non-flammable gas that is safer than hydrogen.
    • However, helium is scarce and expensive, costing about $35 per cubic meter (enough to lift just 1 kg).
    • Challenge with varying Buoyancy:
      • Airships require the ability to vary their buoyancy to adjust for weight changes when picking up or dropping off loads.
      • Solutions such as releasing and refilling helium are impractical due to helium’s high cost and scarcity.

    How Airships are a Promising Solution?

    Airships hold potential as low-emission cargo vehicles due to their unique design:

    • Airships have a high lift-to-drag ratio, meaning they consume far less fuel than aeroplanes for moving the same load.
    • Companies are exploring the use of ballast to regulate airship buoyancy, a method common in hot air balloons and submarines.
    • A French company has created a 200-meter “flying crane” airship called LCA60T, which can pick up water as ballast mid-flight, avoiding the need for specialized ground infrastructure.
    • With concerns about climate change and the aviation industry’s carbon footprint, airships offer a less polluting alternative. They do not burn fossil fuels to lift, making them an eco-friendly choice.
