KMT2C

KMT2C 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 KMT2C rather than just read about it. In short: Lysine N-methyltransferase 2C (KMT2C) also known as myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3) is an enzyme that in humans is encoded by the KMT2C gene. Function This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT-hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a…

Key takeaways

KMT2C belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect KMT2C to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of KMT2C from memory before moving on to harder problems.

Reference excerpt

Lysine N-methyltransferase 2C (KMT2C) also known as myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3) is an enzyme that in humans is encoded by the KMT2C gene.

Function This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT-hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a RING-type zinc finger. This protein is a member of the ASC-2/NCOA6 complex (ASCOM), which possesses histone methylation activity and is involved in transcriptional coactivation. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

Interactions MLL3 has been shown to interact with NCOA6 and RBBP5.

Clinical significance Mutations of the KMT2C gene cause Kleefstra syndrome-2, a neurodevelopmental disorder first described in 2012.

Worked examples

Example 1 — a first encounter with KMT2C

Start with the simplest possible case. Write down what KMT2C 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 KMT2C 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 KMT2C 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 KMT2C

In research: KMT2C 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 KMT2C 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: KMT2C is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 7, Protein stubs, Transcription factors, so understanding it makes those chapters shorter.
In everyday life: Look for KMT2C 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 KMT2C in simple terms?

Lysine N-methyltransferase 2C (KMT2C) also known as myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3) is an enzyme that in humans is encoded by the KMT2C gene. Function This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with…

Why does KMT2C 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 KMT2C?

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.
