GPRC5A

GPRC5A 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 GPRC5A rather than just read about it. In short: Retinoic acid-induced protein 3 is a protein that in humans is encoded by the GPRC5A gene. This gene and its encoded mRNA was first identified as a phorbol ester-induced gene, and named Phorbol Ester Induced Gen 1 (PEIG-1); two years later it was rediscovered as a retinoic acid-inducible gene, and named Retinoic Acid-Inducible Gene 1 (RAIG1).

Key takeaways

GPRC5A belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GPRC5A to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GPRC5A from memory before moving on to harder problems.

Reference excerpt

Retinoic acid-induced protein 3 is a protein that in humans is encoded by the GPRC5A gene. This gene and its encoded mRNA was first identified as a phorbol ester-induced gene, and named Phorbol Ester Induced Gen 1 (PEIG-1); two years later it was rediscovered as a retinoic acid-inducible gene, and named Retinoic Acid-Inducible Gene 1 (RAIG1). Its encoded protein was later named Retinoic acid-induced protein 3.

Function This gene encodes a member of the type 3 G protein-coupled receptor family, characterized by the signature 7-transmembrane domain motif. The encoded protein may be involved in interaction between retinoic acid and G protein signalling pathways. Retinoic acid plays an important role in development, cellular growth, and differentiation. This gene may play a role in embryonic development and epithelial cell differentiation. Tryptamine and other indole related chemicals produced by gut microflora bind and activate the receptor.

Post transcriptional regulation GPRC5A is one of only a handful of genes known in the literature that are post-transcriptionally controlled by miRNAs through their 5'UTR.

Clinical significance GPRC5A is dysregulated in many human cancers and in other diseases.

Worked examples

Example 1 — a first encounter with GPRC5A

Start with the simplest possible case. Write down what GPRC5A 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 GPRC5A 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 GPRC5A 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 GPRC5A

In research: GPRC5A 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 GPRC5A 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: GPRC5A is common in secondary-school and first-year university syllabi. It links to neighbouring topics G protein-coupled receptors, Genes on human chromosome 12, Transmembrane receptor stubs, so understanding it makes those chapters shorter.
In everyday life: Look for GPRC5A 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 GPRC5A in simple terms?

Why does GPRC5A 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 GPRC5A?

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.
