Zinc finger FYVE domain-containing protein 9

Zinc finger FYVE domain-containing protein 9 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 Zinc finger FYVE domain-containing protein 9 rather than just read about it. In short: Zinc finger FYVE domain-containing protein 9 or SARA (SMAD anchor for receptor activation) is a protein that in humans is encoded by the ZFYVE9 gene. SARA contains a double zinc finger (FYVE domain).

Key takeaways

Zinc finger FYVE domain-containing protein 9 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Zinc finger FYVE domain-containing protein 9 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Zinc finger FYVE domain-containing protein 9 from memory before moving on to harder problems.

Reference excerpt

Zinc finger FYVE domain-containing protein 9 or SARA (SMAD anchor for receptor activation) is a protein that in humans is encoded by the ZFYVE9 gene. SARA contains a double zinc finger (FYVE domain). SARA is an anchoring protein involved in TGF beta signaling. It binds to the MH2 domain of the R-SMADs SMAD2 and SMAD3 as well as the type I TGF beta receptors. It facilitates the phosphorylation of the R-SMAD, which subsequently dissociates from SARA and the receptor and binds a coSMAD where they enter the nucleus as transcription factors.

Worked examples

Example 1 — a first encounter with Zinc finger FYVE domain-containing protein 9

Start with the simplest possible case. Write down what Zinc finger FYVE domain-containing protein 9 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 Zinc finger FYVE domain-containing protein 9 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 Zinc finger FYVE domain-containing protein 9 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 Zinc finger FYVE domain-containing protein 9

In research: Zinc finger FYVE domain-containing protein 9 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 Zinc finger FYVE domain-containing protein 9 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: Zinc finger FYVE domain-containing protein 9 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Developmental genes and proteins, FYVE domain, Genes on human chromosome 1, so understanding it makes those chapters shorter.
In everyday life: Look for Zinc finger FYVE domain-containing protein 9 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.
