Melanin-concentrating hormone receptor 2

Melanin-concentrating hormone receptor 2 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 Melanin-concentrating hormone receptor 2 rather than just read about it. In short: Melanin-concentrating hormone receptor 2 (MCH2) also known as G-protein coupled receptor 145 (GPR145) is a protein that in humans is encoded by the MCHR2 gene. MCH2 is also found in dogs, ferrets, and some other primates and carnivores, but is not found in mice or rats.

Key takeaways

Melanin-concentrating hormone receptor 2 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Melanin-concentrating hormone receptor 2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Melanin-concentrating hormone receptor 2 from memory before moving on to harder problems.

Reference excerpt

Melanin-concentrating hormone receptor 2 (MCH2) also known as G-protein coupled receptor 145 (GPR145) is a protein that in humans is encoded by the MCHR2 gene. MCH2 is also found in dogs, ferrets, and some other primates and carnivores, but is not found in mice or rats. This has delayed research into the receptor as a therapeutic target, due to most early pharmaceutical research usually being conducted in small mammals such as mice, rats or rabbits which lack the MCH2 gene and its receptor product.

Clinical significance Treatment of human cells expressing MCHR2 with MCH resulted in upregulation of IDH3A, PCK1 and PFKFB4 and the downregulation of INSIG2 and ACOT8.

Worked examples

Example 1 — a first encounter with Melanin-concentrating hormone receptor 2

Start with the simplest possible case. Write down what Melanin-concentrating hormone receptor 2 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 Melanin-concentrating hormone receptor 2 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 Melanin-concentrating hormone receptor 2 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 Melanin-concentrating hormone receptor 2

In research: Melanin-concentrating hormone receptor 2 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 Melanin-concentrating hormone receptor 2 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: Melanin-concentrating hormone receptor 2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics G protein-coupled receptors, Genes on human chromosome 6, Human proteins, so understanding it makes those chapters shorter.
In everyday life: Look for Melanin-concentrating hormone receptor 2 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.
