KRT83

KRT83 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 KRT83 rather than just read about it. In short: Keratin 83, also known as KRT83, is a protein which humans is encoded by the KRT83 gene. Function The protein encoded by this gene is a member of the keratin gene family.

Key takeaways

  • KRT83 belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect KRT83 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of KRT83 from memory before moving on to harder problems.

Reference excerpt

Keratin 83, also known as KRT83, is a protein which humans is encoded by the KRT83 gene.

Function The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails. The type II hair keratins are clustered in a region of chromosome 12q13 and are grouped into two distinct subfamilies based on structure similarity. One subfamily, consisting of KRTHB1 (KRT81), KRTHB3 (KRT83, this protein), and KRTHB6 (KRT86), is highly related. The other less-related subfamily includes KRTHB2 (KRT82), KRTHB4 (KRT84), and KRTHB5 (KRT85). All hair keratins are expressed in the hair follicle; this hair keratin, as well as KRTHB1 and KRTHB6, is found primarily in the hair cortex.

Clinical significance Mutations in the KRT83 gene have been associated with monilethrix.

Worked examples

Example 1 — a first encounter with KRT83

Start with the simplest possible case. Write down what KRT83 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 KRT83 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 KRT83 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 KRT83

In research
KRT83 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 KRT83 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
KRT83 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 12, Human chromosome 12 gene stubs, so understanding it makes those chapters shorter.
In everyday life
Look for KRT83 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 KRT83 in simple terms?

Keratin 83, also known as KRT83, is a protein which humans is encoded by the KRT83 gene. Function The protein encoded by this gene is a member of the keratin gene family.

Why does KRT83 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 KRT83?

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 KRT83.
