KLF14

KLF14 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 KLF14 rather than just read about it. In short: Krüppel-like factor 14, also known as basic transcription element-binding protein 5 (BTEB5) is a protein that in humans is encoded by the KLF14 gene. The corresponding Klf14 mouse gene is known as Sp6.

Key takeaways

  • KLF14 belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect KLF14 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of KLF14 from memory before moving on to harder problems.

Reference excerpt

Krüppel-like factor 14, also known as basic transcription element-binding protein 5 (BTEB5) is a protein that in humans is encoded by the KLF14 gene. The corresponding Klf14 mouse gene is known as Sp6.

Function KLF14 is a member of the Krüppel-like factor family of transcription factors. It regulates the transcription of various genes, including TGFβRII (the type II receptor for TGFβ). KLF14 is expressed in many tissues, lacks introns, and is subject to parent-specific expression. KLF14 appears to be a master regulator of gene expression in adipose tissue.

Protein structure Like the other members of the KLF family, KLF14 has three zinc-finger domains near the C-terminus, all three of which are of the classical C2H2 type. In the human, they are at amino acids 195–219, 225–249, and 255–277. Human KLF14 is 323 amino acids in length, with a molecular weight of 33,124; in the mouse its length is 325.

Clinical significance There appears to be a connection between KLF14 and coronary artery disease, hypercholesterolemia and type 2 diabetes.

Worked examples

Example 1 — a first encounter with KLF14

Start with the simplest possible case. Write down what KLF14 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 KLF14 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 KLF14 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 KLF14

In research
KLF14 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 KLF14 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
KLF14 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 7, Human chromosome 7 gene stubs, Transcription factors, so understanding it makes those chapters shorter.
In everyday life
Look for KLF14 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 KLF14 in simple terms?

Krüppel-like factor 14, also known as basic transcription element-binding protein 5 (BTEB5) is a protein that in humans is encoded by the KLF14 gene. The corresponding Klf14 mouse gene is known as Sp6.

Why does KLF14 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 KLF14?

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 KLF14.
