PPP1R13B

PPP1R13B 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 PPP1R13B rather than just read about it. In short: Apoptosis-stimulating of p53 protein 1 is a protein that in humans is encoded by the PPP1R13B gene. This gene encodes a member of the ASPP (apoptosis-stimulating protein of p53) family of p53 interacting proteins.

Key takeaways

PPP1R13B belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PPP1R13B to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PPP1R13B from memory before moving on to harder problems.

Reference excerpt

Apoptosis-stimulating of p53 protein 1 is a protein that in humans is encoded by the PPP1R13B gene. This gene encodes a member of the ASPP (apoptosis-stimulating protein of p53) family of p53 interacting proteins. The protein contains four ankyrin repeats and an SH3 domain involved in protein-protein interactions. ASPP proteins are required for the induction of apoptosis by p53-family proteins. They promote DNA binding and transactivation of p53-family proteins on the promoters of proapoptotic genes. Expression of this gene is regulated by the E2F transcription factor.

Worked examples

Example 1 — a first encounter with PPP1R13B

Start with the simplest possible case. Write down what PPP1R13B 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 PPP1R13B 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 PPP1R13B 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 PPP1R13B

In research: PPP1R13B 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 PPP1R13B 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: PPP1R13B is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 14, Human chromosome 14 gene stubs, so understanding it makes those chapters shorter.
In everyday life: Look for PPP1R13B 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.
