Granulocyte colony-stimulating factor receptor

Granulocyte colony-stimulating factor 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 Granulocyte colony-stimulating factor receptor rather than just read about it. In short: The granulocyte colony-stimulating factor receptor (G-CSF-R) also known as CD114 (Cluster of Differentiation 114) is a protein that in humans is encoded by the CSF3R gene. G-CSF-R is a cell-surface receptor for the granulocyte colony-stimulating factor (G-CSF).

Key takeaways

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

Reference excerpt

The granulocyte colony-stimulating factor receptor (G-CSF-R) also known as CD114 (Cluster of Differentiation 114) is a protein that in humans is encoded by the CSF3R gene. G-CSF-R is a cell-surface receptor for the granulocyte colony-stimulating factor (G-CSF). The G-CSF receptors belong to a family of cytokine receptors known as the hematopoietin receptor family. The granulocyte colony-stimulating factor receptor is present on precursor cells in the bone marrow, and, in response to stimulation by G-CSF, initiates cell proliferation and differentiation into mature neutrophilic granulocytes and macrophages. The G-CSF-R is a transmembrane receptor that consists of an extracellular ligand-binding portion, a transmembrane domain, and the cytoplasmic portion that is responsible for signal transduction. GCSF-R ligand-binding is associated with dimerization of the receptor and signal transduction through proteins including Jak, Lyn, STAT, and Erk1/2.

Isoforms The class IV isoform defective for both internalization and differentiation signaling, and colony-stimulating.

Clinical significance Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia. Mutations in the intracellular part of this receptor are also associated with certain types of leukemia. In clinical medicine, there is a suggestion that use of GCSF should be avoided, at least in children and adolescents and perhaps adults, when G-CSFR isoform IV is overexpressed.

Interactions Granulocyte colony-stimulating factor receptor has been shown to interact with Grb2, HCK and SHC1.

Worked examples

Example 1 — a first encounter with Granulocyte colony-stimulating factor receptor

Start with the simplest possible case. Write down what Granulocyte colony-stimulating factor 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 Granulocyte colony-stimulating factor 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 Granulocyte colony-stimulating factor 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 Granulocyte colony-stimulating factor receptor

In research: Granulocyte colony-stimulating factor 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 Granulocyte colony-stimulating factor 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: Granulocyte colony-stimulating factor receptor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clusters of differentiation, Genes on human chromosome 1, Type I cytokine receptors, so understanding it makes those chapters shorter.
In everyday life: Look for Granulocyte colony-stimulating factor 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.
