Interleukin 20 receptor, beta subunit

Interleukin 20 receptor, beta subunit 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 Interleukin 20 receptor, beta subunit rather than just read about it. In short: Interleukin 20 receptor, beta subunit (IL20R2 or IL20RB) is a subunit of the interleukin-20 receptor and interleukin-22 receptor. It is believed to be involved in both pro-inflammatory and anti-inflammatory responses.

Key takeaways

Interleukin 20 receptor, beta subunit belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Interleukin 20 receptor, beta subunit to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Interleukin 20 receptor, beta subunit (IL20R2 or IL20RB) is a subunit of the interleukin-20 receptor and interleukin-22 receptor. It is believed to be involved in both pro-inflammatory and anti-inflammatory responses. IL20RB is found in many organ resident effector cells such as keratinocytes at the skin epidermis, osteoclasts, found in bones, and epithelial cells of the intestine and trachea. IL20RB is also found in some immune cells. The subunit has been linked with multiple diseases, including gastrointestinal diseases and glaucoma.

Structure and function IL20RB is a β-chain with a short intracellular domain. IL20RB, along with the IL-20 receptor, alpha subunit, form the heterodimeric type I interleukin-20 receptor, which binds the cytokines IL-19, IL-20 and IL-24. IL20RB also associates with IL-22 receptor, to form the heterodimeric type II interleukin-20 receptor, which also binds IL-20 and IL-24.

Signaling After a cytokine binds both the IL20RB and the alpha subunit of the IL20 receptor, a signal is sent through the JAK-STAT signaling pathway. This signaling pathway leads STAT to act as a transcription factor, which can gene expression.

Link to Immune System and Disease IL20RB mRNA is present in some immune cells, including monocytes, natural killer cells, B-cells, T-cells, and some hematopoietic stem cells. It is known what role IL20RB plays in these cells. IL20RB is linked with atherosclerosis and gastrointestinal diseases, although its specific roles are unknown.

Glaucoma IL20RB mRNA is expressed in retinal ganglion cells and optic nerves in rats. Mutations in the IL20RB gene are associated with glaucoma. The specific links between IL20RB and glaucoma are unknown, but IL20RB does not have a causative effect on the disease, instead contributing to an increased risk of the disease along with other factors, such as intraocular pressure.

Worked examples

Example 1 — a first encounter with Interleukin 20 receptor, beta subunit

Start with the simplest possible case. Write down what Interleukin 20 receptor, beta 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 20 receptor, beta 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 20 receptor, beta 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 20 receptor, beta subunit

In research: Interleukin 20 receptor, beta 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 20 receptor, beta 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 20 receptor, beta subunit is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 3, Human chromosome 3 gene stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Interleukin 20 receptor, beta 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.
