POU4
BRN-3 is a group of related transcription factors in the POU family. They are also known as class 4 POU domain homeobox proteins. There are three BRN-3 proteins encoded by the following genes: * BRN3A (POU4F1, ) * BRN3B ( POU4F2, ) * BRN3C (POU4F3 POU domain, class 4, transcription factor 3 is a protein that in humans is encoded by the ''POU4F3'' gene. It's a member of BRN-3 group, also known as POU family class 4.

POU4F1
POU domain, class 4, transcription factor 1 (POU4F1) also known as brain-specific homeobox/POU domain protein 3A (BRN3A), homeobox/POU domain protein RDC-1 or Oct-T1 is a protein that in humans is encoded by the ''POU4F1'' gene. BRN3A (POU4F1) is a class IV POU domain-containing transcription factor highly expressed in the developing peripheral sensory nervous system (dorsal root ganglia, trigeminal ganglion, and hindbrain sensory ganglia), certain regions of the central nervous system, retinal neurons called ganglion cells, and in cells of the B- and T-lymphocytic lineages. Discovery Brn3a was initially discovered in mice based on homology to the prototypal POU transcription factors Pit1 ( Pituitary-specific positive transcription factor 1, Pou1f1), Oct1 (Pou2f1), and the Caenorhabditis elegans factor Unc86, and named Brn3. When multiple members of the Brn3 gene class were discovered, it was renamed Brn3.0 and Brn3a by different groups of researchers. Subsequently, the gene w ...

Nomenclature DFNA15 refers to a type of nonsyndromic deafness, with autosomal dominant In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and t ... inheritance.

POU4F2
POU domain, class 4, transcription factor 2 is a protein that in humans is encoded by the ''POU4F2'' gene. Function POU4F2 is a member of the POU-domain family of transcription factors. POU-domain proteins have been observed to play important roles in control of cell identity in several systems. A class IV POU-domain protein, POU4F2 is found in human retina exclusively within a subpopulation of ganglion cells where it may play a role in determining or maintaining the identities of a small subset of visual system neurons. upplied by OMIMref name="entrez" /> Interactions POU4F2 has been shown to interact with Estrogen receptor alpha.

Homeobox
A homeobox is a DNA sequence, around 180 base pairs long, that regulates large-scale anatomical features in the early stages of embryonic development. For instance, mutations in a homeobox may change large-scale anatomical features of the full-grown organism. Homeoboxes are found within genes that are involved in the regulation of patterns of anatomical development (morphogenesis) in animals, fungi, plants, and numerous single cell eukaryotes. Homeobox genes encode homeodomain protein products that are transcription factors sharing a characteristic protein fold structure that binds DNA to regulate expression of target genes. Homeodomain proteins regulate gene expression and cell differentiation during early embryonic development, thus mutations in homeobox genes can cause developmental disorders. Homeosis is a term coined by William Bateson to describe the outright replacement of a discrete body part with another body part, e.g. antennapedia—replacement of the antenna ...

Transcription Factor
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are expressed in the desired cells at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization ( body plan) during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. There are up to 1600 TFs in the human genome. Transcription factors are members of the proteome as well as regulome. TFs work alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment o ...
