Reference excerpt

Interleukin 8 receptor, beta is a chemokine receptor. IL8RB is also known as CXCR2, and CXCR2 is now the IUPHAR Committee on Receptor Nomenclature and Drug classification-recommended name.

Function The protein encoded by this gene is a member of the G-protein-coupled receptor family. This protein is a receptor for interleukin 8 (IL8). It binds to IL8 with high affinity, and transduces the signal through a G-protein-activated second messenger system (Gi/o-coupled). This receptor also binds to chemokine (C-X-C motif) ligand 1 (CXCL1/MGSA), a protein with melanoma growth stimulating activity, and has been shown to be a major component required for serum-dependent melanoma cell growth. In addition, it binds ligands CXCL2, CXCL3, and CXCL5. The angiogenic effects of IL8 in intestinal microvascular endothelial cells are found to be mediated by this receptor. Knockout studies in mice suggested that this receptor controls the positioning of oligodendrocyte precursors in developing spinal cord by arresting their migration. IL8RB, IL8RA, which encodes another high affinity IL8 receptor, and IL8RBP, a pseudogene of IL8RB, form a gene cluster in a region mapped to chromosome 2q33-q36. Mutations in CXCR2 cause hematological traits.

Senescence Knock-down studies involving the chemokine receptor CXCR2 alleviates both replicative and oncogene-induced senescence (OIS) and diminishes the DNA-damage response. Also, ectopic expression of CXCR2 results in premature senescence via a p53-dependent mechanism.

Worked examples

Example 1 — a first encounter with Interleukin 8 receptor, beta

Start with the simplest possible case. Write down what Interleukin 8 receptor, beta 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 8 receptor, beta 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 8 receptor, beta 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 8 receptor, beta

In research: Interleukin 8 receptor, beta 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 8 receptor, beta 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 8 receptor, beta is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chemokine receptors, Clusters of differentiation, Genes on human chromosome 2, so understanding it makes those chapters shorter.
In everyday life: Look for Interleukin 8 receptor, beta 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.
