TFAP2A
Transcription factor AP-2 alpha (Activating enhancer binding Protein 2 alpha), also known as TFAP2A, is a protein that in humans is encoded by the ''TFAP2A'' gene. Function Transcription factor AP-2 alpha is a 52-kD sequence-specific DNA-binding protein that enhances transcription of specific genes by binding to a GC-rich DNA sequence first identified in the cis-regulatory region of SV40 virus DNA and in cis-regulatory regions of a variety of cellular genes. The TFAP2-alpha gene was isolated and found to be retinoic acid-inducible in NT2 teratocarcinoma cells suggesting a potential role for AP-2 alpha in cellular differentiation. During embryonic development, AP-2 alpha is expressed in neural crest cells migrating from the cranial neural folds during neural tube closure, and is also expressed in ectoderm, parts of the central nervous system, limb buds, and mesonephric system suggesting that AP-2 alpha plays an important role in the determination and development of these tis ...

Branchio-oculo-facial Syndrome
Branchio-oculo-facial syndrome (BOFS) is a disease that arises from a mutation in the TFAP2A gene. It is a rare autosomal dominant disorder that starts to affect a child's development before birth. Symptoms of this condition include skin abnormalities on the neck, deformities of the ears and eyes, and other distinctive facial features such a cleft lip along with slow growth, mental retardation and premature graying of hair. Signs and symptoms "Branchio" refers to the branchial arches, also known as the pharyngeal arches, of the affected individual. The branchial arches are structures in the developing embryo that give rise to certain tissues in the neck and facial area. In individuals affected by this condition, the branchial arches fail to develop properly. This leads to some of the physical conditions of this syndrome, which include abnormal patches of skin on the neck and face region and can be abnormally hairy, thin or red and with a high number of blood vessels.

EP300
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 (where E1A = adenovirus early region 1A) also known as EP300 or p300 is an enzyme that, in humans, is encoded by the ''EP300'' gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions (differentiate), and preventing the growth of cancerous tumors. The p300 protein appears to be critical for normal development before and after birth. The EP300 gene is located on the long (q) arm of the human chromosome 22 at position 13.2. This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. EP300 is closely related to another gene, CREB binding protein, which is found on human chromosome 16. Function p300 HAT functions ...

DEK (gene)
The human ''DEK'' gene encodes the DEK protein. Function This gene encodes a protein with one SAP domain. The protein binds to cruciform and superhelical DNA and induces positive supercoils into closed circular DNA. It is also involved in splice site selection during mRNA processing. Chromosomal aberrations involving this region increased expression of this gene and the presence of antibodies against this protein are all associated with various diseases. Interactions ''DEK'' interacts with TFAP2A Transcription factor AP-2 alpha (Activating enhancer binding Protein 2 alpha), also known as TFAP2A, is a protein that in humans is encoded by the ''TFAP2A'' gene.

APC (gene)
Adenomatous polyposis coli (APC) also known as deleted in polyposis 2.5 (DP2.5) is a protein that in humans is encoded by the ''APC'' gene. The APC protein is a negative regulator that controls beta-catenin concentrations and interacts with E-cadherin, which are involved in cell adhesion. Mutations in the ''APC'' gene may result in colorectal cancer. ''APC'' is classified as a tumor suppressor gene. Tumor suppressor genes prevent the uncontrolled growth of cells that may result in cancerous tumors. The protein made by the ''APC'' gene plays a critical role in several cellular processes that determine whether a cell may develop into a tumor. The APC protein helps control how often a cell divides, how it attaches to other cells within a tissue, how the cell polarizes and the morphogenesis of the 3D structures, or whether a cell moves within or away from tissue. This protein also helps ensure that the chromosome number in cells produced through cell division is correct. The APC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cleft Palate
A cleft lip contains an opening in the upper lip that may extend into the nose. The opening may be on one side, both sides, or in the middle. A cleft palate occurs when the palate (the roof of the mouth) contains an opening into the nose. The term orofacial cleft refers to either condition or to both occurring together. These disorders can result in feeding problems, speech problems, hearing problems, and frequent ear infections. Less than half the time the condition is associated with other disorders. Cleft lip and palate are the result of tissues of the face not joining properly during development. As such, they are a type of birth defect. The cause is unknown in most cases. Risk factors include smoking during pregnancy, diabetes, obesity, an older mother, and certain medications (such as some used to treat seizures). Cleft lip and cleft palate can often be diagnosed during pregnancy with an ultrasound exam. A cleft lip or palate can be successfully treated with surge ...

Microphthalmia-associated Transcription Factor
Microphthalmia-associated transcription factor also known as class E basic helix-loop-helix protein 32 or bHLHe32 is a protein that in humans is encoded by the ''MITF'' gene. MITF is a basic helix-loop-helix leucine zipper transcription factor involved in lineage-specific pathway regulation of many types of cells including melanocytes, osteoclasts, and mast cells. The term "lineage-specific", since it relates to MITF, means genes or traits that are only found in a certain cell type. Therefore, MITF may be involved in the rewiring of signaling cascades that are specifically required for the survival and physiological function of their normal cell precursors. MITF, together with transcription factor EB ( TFEB), TFE3 and TFEC, belong to a subfamily of related bHLHZip proteins, termed the MiT-TFE family of transcription factors. The factors are able to form stable DNA-binding homo- and heterodimers. The gene that encodes for MITF resides at the ''mi'' locus in mice, and its prot ...

Van Der Woude Syndrome
Van der Woude syndrome (VDWS) is a genetic disorder characterized by the combination of lower lip pits, cleft lip with or without cleft palate (CL/P), and cleft palate only (CPO). The frequency of orofacial clefts ranges from 1:1000 to 1:500 births worldwide, and there are more than 400 syndromes that involve CL/P. VWS is distinct from other clefting syndromes due to the combination of cleft lip and palate (CLP) and CPO within the same family. Other features frequently associated with VWS include hypodontia in 10-81% of cases, narrow arched palate, congenital heart disease, heart murmur and cerebral abnormalities, syndactyly of the hands, polythelia, ankyloglossia, and adhesions between the upper and lower gum pads. The association between lower lip pits and cleft lip and/or palate was first described by Anne Van der Woude in 1954. The worldwide disease incidence ranges from 1:100,000 to 1:40,000. Genetics Van der Woude syndrome is inherited as an autosomal dominant disease cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IRF6
Interferon regulatory factor 6 also known as IRF6 is a protein that in humans is encoded by the ''IRF6'' gene. Function This gene encodes a member of the interferon regulatory transcription factor (IRF) family. Family members share a highly conserved N-terminal helix-turn-helix DNA-binding domain and a less conserved C-terminal protein-binding domain. The function of IRF6 is related to the formation of connective tissue, for example that of the palate. This gene encodes a member of the interferon regulatory transcription factor (IRF) family. In addition, it has been observed that IRF6 gene is under epigenetic regulation by promoter methylation. Pathology A mutation of the IRF6 gene can lead to the autosomal dominant van der Woude syndrome (VWS) or the related popliteal pterygium syndrome (PPS). Van der Woude syndrome can include cleft lip and palate features along with dental anomalies and lip fistulas. In addition, common alleles in IRF6 have also been associated with ...
