GPR25

GPR25 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 GPR25 rather than just read about it. In short: Probable G-protein coupled receptor 25 is a protein that in humans is encoded by the GPR25 gene. Structure It is a member of the G protein-coupled receptor (GPCR) family and is well conserved in vertebrate evolution containing a canonical DRYLAVV motif in the third transmembrane sequence.

Key takeaways

GPR25 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GPR25 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GPR25 from memory before moving on to harder problems.

Reference excerpt

Probable G-protein coupled receptor 25 is a protein that in humans is encoded by the GPR25 gene.

Structure It is a member of the G protein-coupled receptor (GPCR) family and is well conserved in vertebrate evolution containing a canonical DRYLAVV motif in the third transmembrane sequence. It has a conserved negatively charged N-terminal extracellular peptide comprising a DY candidate sulfation site that is characteristic of many leukocyte chemoattractant receptors for positively charged polypeptides of the chemokine family.

Tissue distribution GPR25 expression is largely restricted to lymphocytes and natural killer (NK) cells.

Function

It has been identified as the receptor for the chemokine-like protein CXCL17.

Worked examples

Example 1 — a first encounter with GPR25

Start with the simplest possible case. Write down what GPR25 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 GPR25 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 GPR25 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 GPR25

In research: GPR25 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 GPR25 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: GPR25 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chemokine receptors, G protein-coupled receptors, Genes on human chromosome 1, so understanding it makes those chapters shorter.
In everyday life: Look for GPR25 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 GPR25 in simple terms?

Probable G-protein coupled receptor 25 is a protein that in humans is encoded by the GPR25 gene. Structure It is a member of the G protein-coupled receptor (GPCR) family and is well conserved in vertebrate evolution containing a canonical DRYLAVV motif in the third transmembrane sequence.

Why does GPR25 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 GPR25?

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.
