SH2D3A

SH2D3A 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 SH2D3A rather than just read about it. In short: SH2 domain-containing protein 3A is a protein that in humans is encoded by the SH2D3A gene. The protein may be useful in Western Blots and ELISAs.

Key takeaways

  • SH2D3A belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect SH2D3A to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of SH2D3A from memory before moving on to harder problems.

Reference excerpt

SH2 domain-containing protein 3A is a protein that in humans is encoded by the SH2D3A gene. The protein may be useful in Western Blots and ELISAs.

Interactions SH2D3A has been shown to interact with the epidermal growth factor receptor. The gene may play a role in JNK activation.

Worked examples

Example 1 — a first encounter with SH2D3A

Start with the simplest possible case. Write down what SH2D3A 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 SH2D3A 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 SH2D3A 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 SH2D3A

In research
SH2D3A 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 SH2D3A 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
SH2D3A is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 19, Human chromosome 19 gene stubs, so understanding it makes those chapters shorter.
In everyday life
Look for SH2D3A 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.

Frequently asked questions

What is SH2D3A in simple terms?

SH2 domain-containing protein 3A is a protein that in humans is encoded by the SH2D3A gene. The protein may be useful in Western Blots and ELISAs.

Why does SH2D3A matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SH2D3A?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on SH2D3A.
