Linkage of human keratin genes
Cytogenetics and Cell Genetics
|January 1, 1986
Summary
Researchers investigated human keratin gene organization. They discovered linkage between type I and type II keratin genes, suggesting all keratin genes may reside in a single genomic region.
Area of Science:
- Molecular Biology
- Genomics
- Cell Biology
Background:
- Keratins are intermediate filament proteins essential for epithelial cell structure.
- Two major families, type I and type II keratins, exist, with at least 20 human genes.
- Keratins are coordinately expressed in epithelial intermediate filaments.
Purpose of the Study:
- To investigate the genomic organization and linkage of human keratin genes.
- To determine if homologous and heterologous keratin genes are physically linked on the human genome.
Main Methods:
- Screening of a human genomic DNA library.
- Analysis of gene linkage patterns for keratin gene families.
Main Results:
- Identified linkage between homologous type I and type II keratin genes.
- Discovered linkage among genes within the type I keratin family.
- Found linkage among genes within the type II keratin family.
- Observed linkage between glycine-rich and non-glycine-rich keratin genes.
Conclusions:
- Keratin genes exhibit significant linkage in the human genome.
- Evidence suggests that all human keratin genes may be clustered in a single genomic region.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
03:17Inheritance of Chromatin Structures
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying DNA...
02:08Gene Conversion
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...
01:09Cytoskeletal Linker Proteins - Plakins
Plakins are large proteins with binding domains for microtubules, microfilaments, intermediate filaments, and membrane-associated protein complexes at cell junctions. Plakin functions are evolutionarily conserved and are primarily involved in organizing the different components of the cytoskeleton by crosslinking them to each other and connecting them to the cell-matrix and cell adhesion complexes. They are also known to interact with signal transducers, serve as scaffolds for signaling...
02:31Synteny and Evolution
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral chromosome underwent...

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
