GABRE

GABRE is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GABRE rather than just read about it. In short: Gamma-aminobutyric acid receptor subunit epsilon is a protein that in humans is encoded by the GABRE gene. The product of this gene belongs to the ligand-gated ionic channel (TC 1.A.9) family.

Key takeaways

  • GABRE belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect GABRE to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of GABRE from memory before moving on to harder problems.

Reference excerpt

Gamma-aminobutyric acid receptor subunit epsilon is a protein that in humans is encoded by the GABRE gene. The product of this gene belongs to the ligand-gated ionic channel (TC 1.A.9) family. It encodes the gamma-aminobutyric acid (GABA) A receptor which is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. This gene encodes an epsilon subunit. It is mapped to chromosome Xq28 in a cluster of genes encoding alpha 3, beta 4 and theta subunits of the same receptor. Alternatively spliced transcript variants encoding different isoforms have been identified. Brainstem expression of ε subunit-containing GABAA receptors is upregulated during pregnancy, particularly in the ventral respiratory group.

Worked examples

Example 1 — a first encounter with GABRE

Start with the simplest possible case. Write down what GABRE claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GABRE before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GABRE ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GABRE

In research
GABRE appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses GABRE in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
GABRE is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome X, Ion channels, Membrane protein stubs, so understanding it makes those chapters shorter.
In everyday life
Look for GABRE outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GABRE in simple terms?

Gamma-aminobutyric acid receptor subunit epsilon is a protein that in humans is encoded by the GABRE gene. The product of this gene belongs to the ligand-gated ionic channel (TC 1.A.9) family.

Why does GABRE matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GABRE?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on GABRE.
