SLC22A12

SLC22A12 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 SLC22A12 rather than just read about it. In short: Solute carrier family 22 (organic anion/cation transporter), member 12, also known as SLC22A12 and URAT1, is a protein which in humans is encoded by the SLC22A12 gene. Function The protein encoded by this gene is a urate transporter and urate-anion exchanger which regulates the level of urate in the blood.

Key takeaways

SLC22A12 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SLC22A12 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SLC22A12 from memory before moving on to harder problems.

Reference excerpt

Solute carrier family 22 (organic anion/cation transporter), member 12, also known as SLC22A12 and URAT1, is a protein which in humans is encoded by the SLC22A12 gene.

Function The protein encoded by this gene is a urate transporter and urate-anion exchanger which regulates the level of urate in the blood. This protein is an integral membrane protein primarily found in kidney. Two transcript variants encoding different isoforms have been found for this gene.

Clinical significance Numerous single nucleotide polymorphisms of this gene are significantly associated with altered (increased or decreased) reabsorption of uric acid by the kidneys. Respectively, these altered rates of reabsorption contribute to hyperuricemia and hypouricemia.

Interactions SLC22A12 has been shown to have a protein-protein interaction with PDZK1.

Inhibition Lesinurad, ruzinurad, darbinurad, verinurad, epaminurad, lingdolinurad, xininurad, puliginurad and dotinurad are urate transporter inhibitors that have been approved to treat gout. Lesinurad enhances urate excretion by inhibition the tubular re-absorption. Probenecid also facilitates uric acid secretion.

Worked examples

Example 1 — a first encounter with SLC22A12

Start with the simplest possible case. Write down what SLC22A12 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 SLC22A12 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 SLC22A12 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 SLC22A12

In research: SLC22A12 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 SLC22A12 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: SLC22A12 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 11, Membrane protein stubs, Solute carrier family, so understanding it makes those chapters shorter.
In everyday life: Look for SLC22A12 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.

Why does SLC22A12 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 SLC22A12?

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.
