Transcription factor SOX-13 is a protein that in humans is encoded by the SOX13 gene. [5] [6]
Transcription factor SOX-13 is a protein that in humans is encoded by the SOX13 gene. [5] [6]
This 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 cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins. It has also been determined to be a type-1 diabetes autoantigen, also known as islet cell antibody 12. [6]
In melanocytic cells SOX13 gene expression may be regulated by MITF. [7]
Antinuclear antibodies are autoantibodies that bind to contents of the cell nucleus. In normal individuals, the immune system produces antibodies to foreign proteins (antigens) but not to human proteins (autoantigens). In some cases, antibodies to human antigens are produced.
Slowly evolving immune-mediated diabetes, or latent autoimmune diabetes in adults (LADA), is a form of diabetes that exhibits clinical features similar to both type 1 diabetes (T1D) and type 2 diabetes (T2D). It is an autoimmune form of diabetes, similar to T1D, but patients with LADA often show insulin resistance, similar to T2D, and share some risk factors for the disease with T2D. Studies have shown that LADA patients have certain types of antibodies against the insulin-producing cells, and that these cells stop producing insulin more slowly than in T1D patients.
Immunodysregulation polyendocrinopathy enteropathy X-linked (or IPEX) syndrome is a rare disease linked to the dysfunction of the gene encoding transcription factor forkhead box P3 (FOXP3), widely considered to be the master regulator of the regulatory T cell lineage. It leads to the dysfunction of CD4+ regulatory T-cells and the subsequent autoimmunity. The disorder is one of the autoimmune polyendocrine syndromes and manifests with autoimmune enteropathy, psoriasiform or eczematous dermatitis, nail dystrophy, autoimmune endocrinopathies, and autoimmune skin conditions such as alopecia universalis and bullous pemphigoid. Management for IPEX has seen limited success in treating the syndrome by bone marrow transplantation.
Dihydrolipoyl transacetylase is an enzyme component of the multienzyme pyruvate dehydrogenase complex. The pyruvate dehydrogenase complex is responsible for the pyruvate decarboxylation step that links glycolysis to the citric acid cycle. This involves the transformation of pyruvate from glycolysis into acetyl-CoA which is then used in the citric acid cycle to carry out cellular respiration.
Chromogranin A or parathyroid secretory protein 1 is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas. In humans, chromogranin A protein is encoded by the CHGA gene.
Centromere protein B also known as major centromere autoantigen B is an autoantigen protein of the cell nucleus. In humans, centromere protein B is encoded by the CENPB gene.
Anti-transglutaminase antibodies (ATA) are autoantibodies against the transglutaminase protein. Antibodies serve an important role in the immune system by detecting cells and substances that the rest of the immune system then eliminates. These cells and substances can be foreign and also can be produced by the body. Antibodies against the body's own products are called autoantibodies. Autoantibodies can sometimes errantly be directed against healthy portions of the organism, causing autoimmune diseases.
Anti-topoisomerase antibodies (ATA) are autoantibodies directed against topoisomerase and found in several diseases, most importantly scleroderma. Diseases with ATA are autoimmune disease because they react with self-proteins. They are also referred to as anti-DNA topoisomerase I antibody.
Protein C-ETS2 is a protein that in humans is encoded by the ETS2 gene. The protein encoded by this gene belongs to the ETS family of transcription factors.
Interferon alpha-1 is a protein that in humans is encoded by the IFNA1 gene.
The human DEKgene encodes the DEK protein.
Tripartite motif-containing protein 21, also known as E3 ubiquitin-protein ligase TRIM21, is a protein that in humans is encoded by the TRIM21 gene. Alternatively spliced transcript variants for this gene have been described but the full-length nature of only one has been determined. It is expressed in most human tissues.
Islet cell autoantigen 1 is a protein that in humans is encoded by the ICA1 gene.
Receptor-type tyrosine-protein phosphatase-like N, also called "IA-2", is an enzyme that in humans is encoded by the PTPRN gene.
Small ubiquitin-related modifier 4 is a protein that in humans is encoded by the SUMO4 gene.
Kruppel-like factor 13, also known as KLF13, is a protein that in humans is encoded by the KLF13 gene.
Receptor-type tyrosine-protein phosphatase N2 (R-PTP-N2) also known as islet cell autoantigen-related protein (ICAAR) and phogrin is an enzyme that in humans is encoded by the PTPRN2 gene. PTPRN and PTPRN2 are both found to be major autoantigens associated with insulin-dependent diabetes mellitus.
Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA. Blood tests such as enzyme-linked immunosorbent assay (ELISA) and immunofluorescence are routinely performed to detect anti-dsDNA antibodies in diagnostic laboratories. They are highly diagnostic of systemic lupus erythematosus (SLE) and are implicated in the pathogenesis of lupus nephritis.
The Cdx protein family is a group of the transcription factor proteins which bind to DNA to regulate the expression of genes. In particular this family of proteins can regulate the Hox genes. They are regulators of embryonic development and hematopoiesis in vertebrates, and are also involved in the development of some types of gastrointestinal cancers and leukemias.
