LRRC8E

LRRC8E 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 LRRC8E rather than just read about it. In short: Leucine-rich repeat-containing protein 8E is a protein that in humans is encoded by the LRRC8E gene. Researchers have found out that this protein, along with the other LRRC8 proteins LRRC8A, LRRC8B, LRRC8C, and LRRC8D, is sometimes a subunit of the heteromer protein volume-regulated anion channel.

Key takeaways

  • LRRC8E belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect LRRC8E to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of LRRC8E from memory before moving on to harder problems.

Reference excerpt

Leucine-rich repeat-containing protein 8E is a protein that in humans is encoded by the LRRC8E gene. Researchers have found out that this protein, along with the other LRRC8 proteins LRRC8A, LRRC8B, LRRC8C, and LRRC8D, is sometimes a subunit of the heteromer protein volume-regulated anion channel. Volume-Regulated Anion Channels (VRACs) are crucial to the regulation of cell size by transporting chloride ions and various organic osmolytes, such as taurine or glutamate, across the plasma membrane, and that is not the only function these channels have been linked to. While LRRC8E is one of many proteins that can be part of VRAC, research has found that it is not as crucial to the activity of the channel in comparison to LRRC8A and LRRC8D. However, while we know that LRRC8A and LRRC8D are necessary for VRAC function, other studies have found that they are not sufficient for the full range of usual VRAC activity. This is where the other LRRC8 proteins come in, such as LRRC8E, as the different composition of these subunits affects the range of specificity for VRACs. In addition to its role in VRACs, the LRRC8 protein family is also associated with agammaglobulinemia-5. Specifically for LRRC8E, there has been a recent study that found that this gene was nominally associated with panic disorder.

Worked examples

Example 1 — a first encounter with LRRC8E

Start with the simplest possible case. Write down what LRRC8E 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 LRRC8E 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 LRRC8E 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 LRRC8E

In research
LRRC8E 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 LRRC8E 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
LRRC8E is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 19, Human chromosome 19 gene stubs, LRR proteins, so understanding it makes those chapters shorter.
In everyday life
Look for LRRC8E 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 LRRC8E in simple terms?

Leucine-rich repeat-containing protein 8E is a protein that in humans is encoded by the LRRC8E gene. Researchers have found out that this protein, along with the other LRRC8 proteins LRRC8A, LRRC8B, LRRC8C, and LRRC8D, is sometimes a subunit of the heteromer protein volume-regulated anion channel.

Why does LRRC8E 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 LRRC8E?

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.
