Reference excerpt

High mobility group protein HMG14 and HMG17 also known as nucleosomal binding domain is a family of evolutionarily related proteins. High mobility group (HMG) proteins constitute a family of relatively low molecular weight non-histone components in chromatin. HMG14 and HMG17 are highly-similar proteins of about 100 amino acid residues; the sequence of chicken HMG14 is almost as similar to chicken HMG17 as it is to mammalian HMG14 polypeptides. The proteins bind to the inner side of the nucleosomal DNA, altering the interaction between the DNA and the histone octamer. It is thought that they may be involved in the process that confers specific chromatin conformations to transcribable regions in the genome. The SMART signature describes a nucleosomal binding domain, which facilitates binding of proteins to nucleosomes in chromatin. The domain is most commonly found in the high mobility group (HMG) proteins, HMG14 and HMG17, however, it is also found in other proteins which bind to nucleosomes, e.g. NBP-45. NBP-45 is a nucleosomal binding protein, first identified in mice, which is related to HMG14 and HMG17. NBP-45 binds specifically to nucleosome core particles, and can function as a transcriptional activator. These findings led to the suggestion that this domain, common to NBP-45, HMG14 and HMG17 is responsible for binding of the proteins to nucleosomes in chromatin.

Examples Human proteins containing this domain include:

HMGN1; HMGN2; HMGN3; HMGN4; HMGN5;

Worked examples

Example 1 — a first encounter with High mobility group protein HMG14 and HMG17

Start with the simplest possible case. Write down what High mobility group protein HMG14 and HMG17 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 High mobility group protein HMG14 and HMG17 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 High mobility group protein HMG14 and HMG17 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 High mobility group protein HMG14 and HMG17

In research: High mobility group protein HMG14 and HMG17 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 High mobility group protein HMG14 and HMG17 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: High mobility group protein HMG14 and HMG17 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Protein domains, so understanding it makes those chapters shorter.
In everyday life: Look for High mobility group protein HMG14 and HMG17 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.
