Nucleoporin 210kDa

Nucleoporin 210kDa 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 Nucleoporin 210kDa rather than just read about it. In short: Nuclear pore glycoprotein-210 (gp210) is an essential trafficking regulator in the eukaryotic nuclear pore complex. Gp-210 anchors the pore complex to the nuclear membrane. and protein tagging reveals its primarily located on the luminal side of double layer membrane at the pore.

Key takeaways

Nucleoporin 210kDa belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nucleoporin 210kDa to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nucleoporin 210kDa from memory before moving on to harder problems.

Reference excerpt

Nuclear pore glycoprotein-210 (gp210) is an essential trafficking regulator in the eukaryotic nuclear pore complex. Gp-210 anchors the pore complex to the nuclear membrane. and protein tagging reveals its primarily located on the luminal side of double layer membrane at the pore. A single polypeptide motif of gp210 is responsible for sorting to nuclear membrane, and indicate the carboxyl tail of the protein is oriented toward the cytoplasmic side of the membrane.

Disassembly and Assembly During eukaryotic mitosis the nuclear envelope disintegrates into vesicles dispersing nuclear lamina proteins and nuclear pore complexes. Nup210 is specifically phosphorylated on the C-terminal (cytoplasmic) domain in mitosis at Ser1880 and is dispersed throughout the endoplasmic reticulum during mitosis as homodimers. Nuclear lamins begin to reassemble around chromosomes at the end of mitosis. Nup210 lags the reassembly process relative to other Nups. and while much of the assembly process can occur without it, the final assembly and dilation of the complexes require Nup210. The replacement of serine at position 1880 with a phosphorylated 'looking' glutamate results in Nup210 complexes that fail to reassemble indicating that dephosphorylation of Nup210 within the final phases of proper assembly is required.

Pathology Recognized by anti-nuclear antibodies found in primary biliary cirrhosis (PBC) anti-Nup210 antibodies correlate with progression toward end stage liver disease. Nup210 is possibly a destructive autoimmune target of the disease. One idea for the loss of tolerance is the increased or abnormal expression of Nup210 in patients with PBC. Anti-mitochondrial, anti-centromere and anti-nup62 are also found in PBC.

Worked examples

Example 1 — a first encounter with Nucleoporin 210kDa

Start with the simplest possible case. Write down what Nucleoporin 210kDa 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 Nucleoporin 210kDa 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 Nucleoporin 210kDa 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 Nucleoporin 210kDa

In research: Nucleoporin 210kDa 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 Nucleoporin 210kDa 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: Nucleoporin 210kDa is common in secondary-school and first-year university syllabi. It links to neighbouring topics Autoantigens, Genes on human chromosome 3, Glycoproteins, so understanding it makes those chapters shorter.
In everyday life: Look for Nucleoporin 210kDa 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.
