Integrin alpha 11

Integrin alpha 11 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 Integrin alpha 11 rather than just read about it. In short: Integrin alpha-11 is a protein that, in humans, is encoded by the ITGA11 gene. This gene encodes an alpha integrin.

Key takeaways

Integrin alpha 11 belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Integrin alpha 11 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Integrin alpha 11 from memory before moving on to harder problems.

Reference excerpt

Integrin alpha-11 is a protein that, in humans, is encoded by the ITGA11 gene. This gene encodes an alpha integrin. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This protein contains an I domain, is expressed in muscle tissue, dimerizes with beta 1 integrin in vitro, and appears to bind collagen in this form. Therefore, the protein may be involved in attaching muscle tissue to the extracellular matrix. Alternative transcriptional splice variants have been found for this gene, but their biological validity is not determined. According to one study, ITGA11 expression is increased in the anterior stroma of corneal buttons excised from the eyes affected by keratoconus. Another study showed that ITGA11 is overexpressed in myofibroblasts in different human fibrotic diseases, including liver cirrhosis, renal fibrosis, and lung fibrosis tissues. ITGA11 has also been found to be upregulated in the tumor stroma of pancreatic ductal adenocarcinoma. Knocking down of ITGA11 in human pancreatic stellate cells led to the inhibition of their differentiation into myofibroblasts and paracrine effect on tumor cells.

Worked examples

Example 1 — a first encounter with Integrin alpha 11

Start with the simplest possible case. Write down what Integrin alpha 11 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 Integrin alpha 11 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 Integrin alpha 11 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 Integrin alpha 11

In research: Integrin alpha 11 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 Integrin alpha 11 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: Integrin alpha 11 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 15, Human chromosome 15 gene stubs, Integrins, so understanding it makes those chapters shorter.
In everyday life: Look for Integrin alpha 11 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.
