Transcription factor SOX-4 is a protein that in humans is encoded by the SOX4 gene. [5] [6] [7]
This intronless gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins, such as syndecan binding protein (syntenin). The protein may function in the apoptosis pathway leading to cell death as well as to tumorigenesis and may mediate downstream effects of parathyroid hormone (PTH) and PTH-related protein (PTHrP) in bone development. The solution structure has been resolved for the HMG-box of a similar mouse protein. [7]
Sox4 is expressed in lymphocytes (B and T) and is required for B lymphocyte development. [8]
A genomic region close to the SOX4 gene has been associated with endometrial cancer development. [9] [10]
Sex-determining region Y protein (SRY), or testis-determining factor (TDF), is a DNA-binding protein encoded by the SRY gene that is responsible for the initiation of male sex determination in therian mammals. SRY is an intronless sex-determining gene on the Y chromosome. Mutations in this gene lead to a range of disorders of sex development with varying effects on an individual's phenotype and genotype.
SOX genes encode a family of transcription factors that bind to the minor groove in DNA, and belong to a super-family of genes characterized by a homologous sequence called the HMG-box. This HMG box is a DNA binding domain that is highly conserved throughout eukaryotic species. Homologues have been identified in insects, nematodes, amphibians, reptiles, birds and a range of mammals. However, HMG boxes can be very diverse in nature, with only a few amino acids being conserved between species.
SRY -box 2, also known as SOX2, is a transcription factor that is essential for maintaining self-renewal, or pluripotency, of undifferentiated embryonic stem cells. Sox2 has a critical role in maintenance of embryonic and neural stem cells.
Transcription factor SOX-9 is a protein that in humans is encoded by the SOX9 gene.
Transcription factor SOX-10 is a protein that in humans is encoded by the SOX10 gene.
Transcription factor SOX-3 is a protein that in humans is encoded by the SOX3 gene. This gene encodes a member of the SOX family of transcription factors involved in the regulation of embryonic brain development and in determination of cell fate. The encoded protein acts as a transcriptional activator.
Transcription factor SOX-5 is a protein that in humans is encoded by the SOX5 gene.
Transcription factor SOX-13 is a protein that in humans is encoded by the SOX13 gene.
Transcription factor 7 is the gene that in humans encodes for the TCF1 protein.
Transcription factor SOX-18 is a protein that in humans is encoded by the SOX18 gene.
Transcription factor SOX-11 is a protein that in humans is encoded by the SOX11 gene.
Transcription factor SOX-8 is a protein that in humans is encoded by the SOX8 gene.
Protein SOX-15 is a protein that in humans is encoded by the SOX15 gene.
SOX12 is a protein that in humans is encoded by the SOX12 gene. Sox12 belongs to the SoxC group of Sox family of transcription factors, together with Sox4 and Sox11. Sox12-null knockout mice appear normal, unlike Sox4 or Sox11 knockout mice. This probably comes from functional redundancy with Sox4 and Sox11. Sox12 is a weaker activator than both Sox4 and Sox11 in mouse.
Transcription factor SOX-14 is a protein that in humans is encoded by the SOX14 gene.
Transcription factor SOX-21 is a protein that in humans is encoded by the SOX21 gene. It is a member of the Sox gene family of transcription factors.
SOX1 is a gene that encodes a transcription factor with a HMG-box DNA-binding domain and functions primarily in neurogenesis. SOX1, SOX2 and SOX3, members of the SOX gene family, contain transcription factors related to SRY, the testis-determining factor.
SoxC group is group C of Sry-related HMG box proteins transcription factors. SoxC genes play an important role in determining the cell fate of neuronal mesenchymal progenitor cells in many developmental processes.
SRY -box 30 is a protein that in humans is encoded by the SOX30 gene.
SRY-box 7 is a protein that in humans is encoded by the SOX7 gene.
