Glucagon-like peptide-2 receptor

Glucagon-like peptide-2 receptor 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 Glucagon-like peptide-2 receptor rather than just read about it. In short: Glucagon-like peptide-2 receptor (GLP-2R) is a protein that in human is encoded by the GLP2R gene located on chromosome 17. Function The GLP2 receptor (GLP2R) is a G protein-coupled receptor superfamily member closely related to the glucagon receptor (GLP1 receptor).

Key takeaways

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

Reference excerpt

Glucagon-like peptide-2 receptor (GLP-2R) is a protein that in human is encoded by the GLP2R gene located on chromosome 17.

Function The GLP2 receptor (GLP2R) is a G protein-coupled receptor superfamily member closely related to the glucagon receptor (GLP1 receptor). Glucagon-like peptide-2 (GLP2) is a 33-amino acid proglucagon-derived peptide produced by intestinal enteroendocrine cells. Like glucagon-like peptide-1 (GLP1) and glucagon itself, it is derived from the proglucagon peptide encoded by the GCG gene. GLP2 stimulates intestinal growth and upregulates villus height in the small intestine, concomitant with increased crypt cell proliferation and decreased enterocyte apoptosis. Moreover, GLP2 prevents intestinal hypoplasia resulting from total parenteral nutrition. GLP2R, a G protein-coupled receptor superfamily member is expressed in the gut and closely related to the glucagon receptor (GCGR) and the receptor for GLP1 (GLP1R).

Worked examples

Example 1 — a first encounter with Glucagon-like peptide-2 receptor

Start with the simplest possible case. Write down what Glucagon-like peptide-2 receptor 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 Glucagon-like peptide-2 receptor 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 Glucagon-like peptide-2 receptor 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 Glucagon-like peptide-2 receptor

In research: Glucagon-like peptide-2 receptor 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 Glucagon-like peptide-2 receptor 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: Glucagon-like peptide-2 receptor is common in secondary-school and first-year university syllabi. It links to neighbouring topics G protein-coupled receptors, Genes on human chromosome 17, Transmembrane receptor stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Glucagon-like peptide-2 receptor 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.
