Reference excerpt

Immunoglobulin lambda variable 6-57 is a protein which is encoded by the IGLV6-57 gene in humans. This gene is primarily expressed in the lymphatic system. IGLV6-57 is an extracellular protein that has been predicted to reside within the cytoplasm of cells. The function of IGLV6-57 is predicted to be involved in the immune response and enabling antigen binding activity. This prediction also matches with pathogen recognition from antibodies utilizing IGLV6-57 light chains.

Gene

Aliases Known aliases of IGLV6-57 include V1-22 or IGLV657.

Locus Human IGLV6-57 gene is found on the forward (+) strand at the locus NC_000022.11. The gene ranges from position 22026076 to position 22922913 on chromosome 22.

mRNA IGLV6-57's transcript is reported to be around 478 nucleotides long. It has two exons separated between one intron.

Expression pattern IGLV6-57 is moderately expressed in spleen, lymph node, and tonsil tissue.

Transcript IGLV6-57 gene contains no alternatively spliced forms because it is an immunoglobulin variable-region gene segment, not a complete antibody gene.

Protein

Protein characteristics The predicted molecular weight of IGLV6-57 is 12.566 kDa, and it has a predicted isoelectric point (pI) of pH 4.59. In terms of amino acid composition, IGLV6-57 has a relatively proportion of polar amino acids serine, glycine, and threonine. It also is relatively poor in histidine, methionine, and tryptophan.

Isoforms Immunoglobulin Lambda Variable 6-57 primarily expresses a single protein isoform.

Secondary structure The predicted secondary structure of IGLV6-57 is composed primarily of β strands.

Teritiary structure The predicted teritiary structure of IGLV6-57 consists of two antiparallel β sheets stabilized by conserved intradomain disulfide bond.

Post-translational modifications

Disulfide bond formation Conceptual translation of human IGLV6-57 mRNA revealed two conserved cysteine residues at position 20 and 89 and are predicted to form an intradomain disulfide bond.

Cellular localization Computational prediction have identifies the IGLV6-57 protein in the extracellular and cytoplasm location. IGLV6-57 is predicted to be a soluble protein.

Regulation and expression

Promoters No promoter was identified in the analyzed upstream sequence of IGLV6-57 using computational promoter prediction methods.

Transcription factors The following table summarizes transcription factors predicted to bind highly conserved regions of the IGLV6-57 sequence.

Expression

Tissue specificity According to RNA-seq data, IGLV6-57 is expressed most highly in lymph node, spleen, and appendix tissue.

Embryonic development IGLV6-57 expression is highest in the fetal adrenal gland during mid-gestation (16–18 weeks), with lower expression in several other fetal tissues. No specific role in embryonic development has been established.

Differential expression IGLV6-57 has been observed to be expressed at higher levels in beta-catenin-depleted cells than in untreated control cells. IGLV6-57 has been observed to be expressed at higher levels in tumor tissue than in adjacent normal tissue.

Interacting proteins The StringNetwork database indicates that the following proteins have been found to interact with the IGLV6-57 protein.

Homology and evolution

Orthologs IGLV6-57 has orthologs in Mammalia, Aves, Reptillia, and Amphibia. A table of selected orthologs is listed below.

Selected orthologs of the homo sapiens IGLV6-57 protein

Evolutionary history IGLV6-57 is not a highly conserved gene due to evolutionary divergence driven by the adaptive immune system. The most evolutionary distant ortholog of IGLV6-57 is in the Sardinian tree frog (Hyla sarda); and it is conserved from Amphibia to Mammalia, with no detectable orthologs in invertebrates.

Paralogs IGLV6-57 contains numerous paralogous genes located within the immunoglobulin lambda locus on chromosome 22.

Clinical significance IGLV6-57 has been a linked site for an amyloid-associated residue change associated with AL amyloidosis. Additionally, proteins from this specific lambda light chain class is likely to unfold, exposing the hydrophobic core of the protein. Due to structural instability, the IGLV6-57 gene segment frequently misfolds.

Worked examples

Example 1 — a first encounter with Iglv6-57

Start with the simplest possible case. Write down what Iglv6-57 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 Iglv6-57 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 Iglv6-57 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 Iglv6-57

In research: Iglv6-57 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 Iglv6-57 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: Iglv6-57 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Genes on human chromosome 22, Human genes, Human proteins, so understanding it makes those chapters shorter.
In everyday life: Look for Iglv6-57 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.
