Reference excerpt

Interleukin 12 receptor, beta 2 subunit is a subunit of the interleukin 12 receptor. IL12RB2 is its human gene. IL12RB2 orthologs have been identified in all mammals for which complete genome data are available. The protein encoded by this gene is a type I transmembrane protein identified as a subunit of the interleukin 12 receptor complex. The co-expression of this and IL12Rβ1 proteins was shown to lead to the formation of high-affinity IL12 binding sites and reconstitution of IL12 dependent signaling. While the IL12Rβ1 subunit is constitutively expressed, the expression of the IL12RB2 gene is up-regulated by interferon gamma. In Th1 cells, IL-12 signaling through the IL12 receptor leads to the phosphorylation of STAT4 and continued Th1 differentiation. The IL12Rβ2 subunit plays an important role in Th1 cell differentiation, since its absence leads to an abortive Th1 differentiation that has dysfunctional production of Th1 effector molecules. The up-regulation of this gene is found to be associated with a number of infectious diseases, such as Crohn's disease and leprosy, which is thought to contribute to the inflammatory response and host defense.

Interactions Interleukin 12 receptor, beta 2 subunit has been shown to interact with Janus kinase 2.

Worked examples

Example 1 — a first encounter with Interleukin 12 receptor, beta 2 subunit

Start with the simplest possible case. Write down what Interleukin 12 receptor, beta 2 subunit 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 Interleukin 12 receptor, beta 2 subunit 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 Interleukin 12 receptor, beta 2 subunit 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 Interleukin 12 receptor, beta 2 subunit

In research: Interleukin 12 receptor, beta 2 subunit 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 Interleukin 12 receptor, beta 2 subunit 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: Interleukin 12 receptor, beta 2 subunit is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 1, Human chromosome 1 gene stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Interleukin 12 receptor, beta 2 subunit 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.
