Olfactomedin 1

Olfactomedin 1 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 Olfactomedin 1 rather than just read about it. In short: Olfactomedin 1, also known as noelin 1 or pancortin, is a protein that in humans is encoded by the OLFM1 gene. The name noelin stands for "neuronal olfactomedin-related endoplasmic reticulum-localized 1".

Key takeaways

Olfactomedin 1 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Olfactomedin 1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Olfactomedin 1 from memory before moving on to harder problems.

Reference excerpt

Olfactomedin 1, also known as noelin 1 or pancortin, is a protein that in humans is encoded by the OLFM1 gene. The name noelin stands for "neuronal olfactomedin-related endoplasmic reticulum-localized 1". This gene product shares extensive sequence similarity with the rat neuronal olfactomedin-related ER localized protein. While the exact function of the encoded protein is not known, its abundant expression in brain suggests that it may have an essential role in nerve tissue. Several alternatively spliced transcripts encoding different isoforms have been found for this gene.

Cancer OLFM1 gene has been detected progressively overexpressed in Human papillomavirus-positive neoplastic keratinocytes derived from uterine cervical preneoplastic lesions at different levels of malignancy. For this reason, this gene is likely to be associated with tumorigenesis and may be a potential prognostic marker for uterine cervical preneoplastic lesions progression.

Worked examples

Example 1 — a first encounter with Olfactomedin 1

Start with the simplest possible case. Write down what Olfactomedin 1 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 Olfactomedin 1 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 Olfactomedin 1 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 Olfactomedin 1

In research: Olfactomedin 1 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 Olfactomedin 1 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: Olfactomedin 1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 9, Human chromosome 9 gene stubs, Olfactomedins, so understanding it makes those chapters shorter.
In everyday life: Look for Olfactomedin 1 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.
