Mitochondrial folate transporter

Mitochondrial folate transporter 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 Mitochondrial folate transporter rather than just read about it. In short: The mitochondrial folate transporter (MTF) is a transport protein that facilitates the transfer of tetrahydrofolate across the inner mitochondrial membrane. It is encoded by the SLC25A32 gene and belongs to the mitochondrial carrier superfamily.

Key takeaways

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

Reference excerpt

The mitochondrial folate transporter (MTF) is a transport protein that facilitates the transfer of tetrahydrofolate across the inner mitochondrial membrane. It is encoded by the SLC25A32 gene and belongs to the mitochondrial carrier superfamily.

History The mitochondrial folate transporter was first described in 2000.

Role in pathology Mutations of the SLC25A32 gene cause the condition putatively called "riboflavin-responsive exercise intolerance" (RREI), also known as SLC25A32 deficiency. The first case report linking this condition to SLC25A32 was published in 2016. Several additional cases of SLC25A32 deficiency have been described since. The phenotype of the patients is reminiscent of multiple acyl-CoA dehydrogenase deficiency (MADD). According to a review published in 2020, mutations of the SLC25A32 gene have been shown to cause neural tube defects in mice, and they have been associated with several human cases, based on a re-sequencing of DNA of patients with neural tube defects.

Worked examples

Example 1 — a first encounter with Mitochondrial folate transporter

Start with the simplest possible case. Write down what Mitochondrial folate transporter 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 Mitochondrial folate transporter 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 Mitochondrial folate transporter 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 Mitochondrial folate transporter

In research: Mitochondrial folate transporter 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 Mitochondrial folate transporter 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: Mitochondrial folate transporter is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 8, Human genes, Mitochondrial proteins, so understanding it makes those chapters shorter.
In everyday life: Look for Mitochondrial folate transporter 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.
