KIF2A

KIF2A 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 KIF2A rather than just read about it. In short: Kinesin-like protein KIF2A is a protein that in humans is encoded by the KIF2A gene. In mice, KIF2A is essential for proper neurogenesis and deficiency of KIF2A in mature neurons results in the loss of those neurons.

Key takeaways

  • KIF2A belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect KIF2A to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of KIF2A from memory before moving on to harder problems.

Reference excerpt

Kinesin-like protein KIF2A is a protein that in humans is encoded by the KIF2A gene. In mice, KIF2A is essential for proper neurogenesis and deficiency of KIF2A in mature neurons results in the loss of those neurons. Kinesins, such as KIF2, are microtubule-associated motor proteins. For background information on kinesins, see MIM 148760.[supplied by OMIM]

Worked examples

Example 1 — a first encounter with KIF2A

Start with the simplest possible case. Write down what KIF2A 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 KIF2A 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 KIF2A 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 KIF2A

In research
KIF2A 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 KIF2A 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
KIF2A is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 5, Human chromosome 5 gene stubs, Human proteins, so understanding it makes those chapters shorter.
In everyday life
Look for KIF2A 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.

How to study KIF2A in 20 minutes

  1. Read the reference excerpt below once, without taking notes.
  2. Close the page and write down what KIF2A means in your own words.
  3. Compare your version with the excerpt and mark what you missed.
  4. Work through the three examples above with pen and paper.
  5. Explain KIF2A out loud to somebody else — or to Teacher Smith in the lgStudy chat.

Frequently asked questions

What is KIF2A in simple terms?

Kinesin-like protein KIF2A is a protein that in humans is encoded by the KIF2A gene. In mice, KIF2A is essential for proper neurogenesis and deficiency of KIF2A in mature neurons results in the loss of those neurons.

Why does KIF2A 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 KIF2A?

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 KIF2A.
