Tachykinin receptor 2

Tachykinin 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 Tachykinin receptor 2 rather than just read about it. In short: Substance-K receptor is a protein that in humans is encoded by the TACR2 gene. Function This gene belongs to a family of genes that function as receptors for tachykinins.

Key takeaways

Tachykinin 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 Tachykinin receptor 2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Tachykinin receptor 2 from memory before moving on to harder problems.

Reference excerpt

Substance-K receptor is a protein that in humans is encoded by the TACR2 gene.

Function This gene belongs to a family of genes that function as receptors for tachykinins. Receptor affinities are specified by variations in the 5'-end of the sequence. The receptors belonging to this family are characterized by interactions with G proteins and 7 hydrophobic transmembrane regions. This gene encodes the receptor for the tachykinin neuropeptide substance K, also referred to as neurokinin A.

Selective Ligands Several selective ligands for NK2 are now available, and although most of the compounds developed so far are peptides, one small-molecule antagonist Saredutant is currently in clinical trials as an anxiolytic and antidepressant.

Agonists GR-64349 - potent and selective agonist, EC50 3.7nM, 7-amino acid polypeptide chain. CAS# 137593-52-3

Antagonists Ibodutant - failed its Phase 3 trial for IBS treatment in 2015, and abandoned by Menarini Saredutant - mixed but mostly negative Phase 3 trial results in 2009, and abandoned by Sanofi-Aventis GR-159897 Nepadutant MEN-10376 - potent and selective antagonist, 7-amino acid polypeptide chain. CAS# 135306-85-3

Worked examples

Example 1 — a first encounter with Tachykinin receptor 2

Start with the simplest possible case. Write down what Tachykinin 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 Tachykinin 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 Tachykinin 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 Tachykinin receptor 2

In research: Tachykinin 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 Tachykinin 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: Tachykinin 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 10, Transmembrane receptor stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Tachykinin 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.
