Homeotic gene Homeotic genes are genes which regulate the development of anatomical structures in various organisms such as insects, mammals, and plants.This regulation is done via the programming of various transcription factors by the homeotic genes, and these factors affect genes through regulatory genetic pathways.ne of the most commonly studied model organisms in regards to homeotic genes is Drosophila, specifically Drosophila melanogaster. The homeotic genes of this organism occur in either the Antennapedia complex (ANT-C) or the Bithorax complex (BX-C).

FOXP2 Forkhead box protein P2 (FOXP2) is a protein that, in humans, is encoded by the FOXP2 gene, also known as CAGH44, SPCH1 or TNRC10, and is required for proper development of speech and language. Initially identified as the genetic factor of speech disorder in KE family, its gene is the first gene discovered associated with speech and language.

SRY Gene  (Protein Coding) This intronless gene encodes a transcription factor that is a member of the high mobility group (HMG)-box family of DNA-binding proteins.This protein is the testis-determining factor (TDF), which initiates male sex determination.Mutations in this gene give rise to XY females with gonadal dysgenesis (Swyer syndrome); translocation of part of the Y chromosome containing this gene to the X chromosome causes XX male syndrome.his intronless gene encodes a transcription factor that is a member of the high mobility group (HMG)-box family of DNA-binding proteins.

MLH1 This gene was identified as a locus frequently mutated in hereditary nonpolyposis colon cancer (HNPCC). It is a human homolog of the E. coli DNA mismatch repair gene mutL, consistent with the characteristic alterations in microsatellite sequences (RER+phenotype) found in HNPCC.Alternative splicing results in multiple transcript variants encoding distinct isoforms.t often is associated with germ-line mutations in the mutS homolog 2, colon cancer, nonpolyposis type 1 (Escherichia coli) gene, MSH2, and the mutL homolog 1, colon cancer, nonpolyposis type 2 (E. coli) gene, MLH1 (similar to hereditary nonpolyposis colon cancer [HNPCC]).

Homeoboxes Homeobox genes are a large family of similar genes that direct the formation of many body structures during early embryonic development. In humans, the homeobox gene family contains an estimated 235 functional genes and 65 pseudogenes (structurally similar genes that do not provide instructions for making proteins).

The Nonsense of White Genes In human genetics, Haplogroup I-M170 is a Y-chromosome DNA haplogroup, a subgroup of haplogroup IJ, itself a derivative of Haplogroup IJK. Y-DNA Haplogroup I-M170 is predominantly a European haplogroup and it is considered as the only native European Haplogroup.-chromosome analysis had suggested Paleolithic ancestry among populations in the Iberian Peninsula and that Iberia may have played a role in the re-population of western Europe after the last glaciation.

DispatchHomeodomain Proteins: Homeotic genes seek partners Heterodimer formation by these two homeodomain proteins may enhance the DNA-binding specificity of mec-3 by allowing unc-86 to act as a coupling protein that recruits mec-3 to sites where unc-86 is already bound.he exd gene has recently been cloned by Rauskolb et al. [9] , and, intriguingly, turns out to encode a homeodomain protein with some indications of having a particular sequence relationship to the yeast a1 gene product.

- Parkinson disease gene: A gene involved in the causation of Parkinson disease. There are a number of different autosomal dominant and recessive forms of Parkinson disease.They are called PARK1, PARK2, and so on: PARK1 is an autosomal dominant trait and is due to mutation in the alpha-synuclein gene (SNCA) on chromosome 4q21; 2  PARK2 is an autosomal recessive trait and is due to mutation in the gene encoding parkin on chromosome 6q25.2-q27; 3  PARK3 is an autosomal dominant trait and is due to a gene on chromosome 2p13;

Homeoboxes Homeobox genes are a large family of similar genes that direct the formation of many body structures during early embryonic development. In humans, the homeobox gene family contains an estimated 235 functional genes and 65 pseudogenes (structurally similar genes that do not provide instructions for making proteins).ecause homeobox genes have so many important functions, mutations in these genes are responsible for a variety of developmental disorders. For example, mutations in the HOX group of homeobox genes typically cause limb malformations.

- The p53 gene like the Rb gene, is a tumor suppressor gene, i.e., its activity stops the formation of tumors.If a person inherits only one functional copy of the p53 gene from their parents, they are predisposed to cancer and usually develop several independent tumors in a variety of tissues in early adulthood.n the cell, p53 protein binds DNA, which in turn stimulates another gene to produce a protein called p21 that interacts with a cell division-stimulating protein (cdk2). When p21 is complexed with cdk2 the cell cannot pass through to the next stage of cell division.

What is ataxia telangiectasia? In the past, ATM mutation carriers were identified mainly because they were parents of a child with A-T. With the cloning of the ATM gene, however, physicians or cancer genetics professionals can now conduct genetic testing, analyzing patients' DNA to look for A-T–associated mutations in the ATM gene.

- Multiple hereditary exostosis (MHE) is an autosomal dominant disorder characterized by the development of multiple osteochondromas and a defect in the EXT-1, EXT-2, or EXT-3 genes. EXT-1 patients have higher rates of sarcomatous change when compared to those with a defect in EXT-2.

What is Domotics? People may refer to domotics as home automation or  smart home systems, depending on the region they live in and their approach to the field. Domotics can encompass both hardware and software, with customized systems built specifically for the purpose along with existing systems which are modified. Many architects are beginning to consider domotics in home design and construction. When the system is integrated into a house as it is built, it tends to be cheaper to install and maintain, especially if an architect thinks ahead and provides flexibility so that people can add options and modifications over time.
