PPP1R3C

PPP1R3C 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 PPP1R3C rather than just read about it. In short: Protein phosphatase 1 regulatory subunit 3C also known as PTG is an enzyme that in humans is encoded by the PPP1R3C gene. Function Protein phosphatase-1 (PP1) participates in the regulation of a wide variety of cellular functions by reversible protein phosphorylation.

Key takeaways

  • PPP1R3C belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect PPP1R3C to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of PPP1R3C from memory before moving on to harder problems.

Reference excerpt

Protein phosphatase 1 regulatory subunit 3C also known as PTG is an enzyme that in humans is encoded by the PPP1R3C gene.

Function Protein phosphatase-1 (PP1) participates in the regulation of a wide variety of cellular functions by reversible protein phosphorylation. The ability of PP1 to regulate diverse functions resides in its capacity to interact with a variety of regulatory subunits that may target PP1 to specific subcellular locations, modulate its substrate specificity, and allow its activity to be responsive to extracellular signals. Several targeting subunits of PP1 have been identified, including PPP1R5, the glycogen-binding subunits GM, GL, PTG and R6 and PPP1R4, and the nuclear inhibitor of PP1 (PPP1R8).

Worked examples

Example 1 — a first encounter with PPP1R3C

Start with the simplest possible case. Write down what PPP1R3C 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 PPP1R3C 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 PPP1R3C 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 PPP1R3C

In research
PPP1R3C 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 PPP1R3C 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
PPP1R3C is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 10, Human chromosome 10 gene stubs, Protein stubs, so understanding it makes those chapters shorter.
In everyday life
Look for PPP1R3C 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 PPP1R3C in simple terms?

Protein phosphatase 1 regulatory subunit 3C also known as PTG is an enzyme that in humans is encoded by the PPP1R3C gene. Function Protein phosphatase-1 (PP1) participates in the regulation of a wide variety of cellular functions by reversible protein phosphorylation.

Why does PPP1R3C 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 PPP1R3C?

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 PPP1R3C.
