Neutrophil cytosolic factor 1

Neutrophil cytosolic factor 1 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 Neutrophil cytosolic factor 1 rather than just read about it. In short: Neutrophil cytosol factor 1, also known as p47phox, is a protein that in humans is encoded by the NCF1 gene. Function The protein encoded by this gene is a 47 kDa cytosolic subunit of neutrophil NADPH oxidase.

Key takeaways

Neutrophil cytosolic factor 1 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Neutrophil cytosolic factor 1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Neutrophil cytosolic factor 1 from memory before moving on to harder problems.

Reference excerpt

Neutrophil cytosol factor 1, also known as p47phox, is a protein that in humans is encoded by the NCF1 gene.

Function The protein encoded by this gene is a 47 kDa cytosolic subunit of neutrophil NADPH oxidase. This oxidase is a multicomponent enzyme that is activated to produce superoxide anion. Mutations in this gene have been associated with chronic granulomatous disease. Genetic variability in the NCF1 gene has been found to be related to a higher chance of getting autoimmune diseases such as Sjögren's syndrome, rheumatoid arthritis and lupus erythematosus.

Interactions Neutrophil cytosolic factor 1 has been shown to interact with:

Moesin, Neutrophil cytosolic factor 4, and RELA.

Therapies A Phase 1/2 open-label clinical trial began in the U.S. in late 2024 to evaluate PM359, a gene therapy developed by Prime Medicine, in patients with chronic granulomatous disease caused by mutations in the NCF1 gene.

Worked examples

Example 1 — a first encounter with Neutrophil cytosolic factor 1

Start with the simplest possible case. Write down what Neutrophil cytosolic factor 1 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 Neutrophil cytosolic factor 1 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 Neutrophil cytosolic factor 1 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 Neutrophil cytosolic factor 1

In research: Neutrophil cytosolic factor 1 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 Neutrophil cytosolic factor 1 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: Neutrophil cytosolic factor 1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 7, Protein stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Neutrophil cytosolic factor 1 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.
