Description: Homo sapiens WD repeat domain 19 (WDR19), mRNA. RefSeq Summary (NM_025132): The protein encoded by this gene is a member of the WD (tryptophan-aspartic acid) repeat family, which is a large family of structurally-related proteins known to participate in a wide range of cellular processes. Each WD repeat typically contains about 40 amino acids that are usually bracketed by glycine-histidine and tryptophan-aspartic acid (WD) dipeptides. This protein contains six WD repeats, three transmembrane domains, and a clathrin heavy-chain repeat. Mutations in this gene have been described in individuals with a wide range of disorders affecting function of the cilium. These disorders are known as ciliopathies, and include Jeune syndrome, Sensenbrenner syndromes, Senior-Loken syndrome, combined or isolated nephronophthisis (NPHP), and retinitis pigmentosa (RP). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015].

ID:WDR19_HUMAN DESCRIPTION: RecName: Full=WD repeat-containing protein 19; FUNCTION: May be involved in cilia function and/or assembly. SUBCELLULAR LOCATION: Cell projection, cilium (By similarity). Cytoplasm, cytoskeleton, cilium basal body (By similarity). Note=Localizes to photoreceptor connecting cilia, to the base of motile cilia in brain ependymal cells and to the base of and along primary cilia in kidney cells (By similarity). TISSUE SPECIFICITY: Some isoforms are tissue-specific. Highly expressed in the prostate. Lower expression in the cerebellum, pituitary gland, fetal lung, and pancreas. In normal prostate, expressed in both basal and luminal epithelial cells. No expression detected in fibromuscular stromal cells, endothelial cells, or infiltrating lymphocytes. Uniformed expression in prostate adenocarcinoma cells. DEVELOPMENTAL STAGE: Expressed in fetal lung. INDUCTION: By androgenic hormones. Expression increased 3-fold in an androgen-stimulated androgen-sensitive prostate adenocarcinoma cell line compared with androgen-deprived cells. DISEASE: Defects in WDR19 are the cause of cranioectodermal dysplasia type 4 (CED4) [MIM:614378]. CED4 is a disorder primarily characterized by craniofacial, skeletal and ectodermal abnormalities. Clinical features include craniosynostosis, narrow rib cage, short limbs, brachydactyly, hypoplastic and widely spaced teeth, sparse hair, skin laxity and abnormal nails. Nephronophthisis leading to progressive renal failure, hepatic fibrosis, heart defects, and retinitis pigmentosa have also been described. DISEASE: Defects in WDR19 are the cause of asphyxiating thoracic dystrophy type 5 (ATD5) [MIM:614376]. ATD5 is an autosomal recessive chondrodysplasia characterized by a severely constricted thoracic cage, short-limbed short stature, and polydactyly. It often leads to death in infancy because of respiratory insufficiency. Retinal degeneration, cystic renal disease and hepatic disease can be present in affected individuals who survive early childhood. DISEASE: Defects in WDR19 are the cause of nephronophthisis type 13 (NPHP13) [MIM:614377]. NPHP13 is an autosomal recessive disorder resulting in end-stage renal disease. It is a progressive tubulo-interstitial kidney disorder histologically characterized by modifications of the tubules with thickening of the basement membrane, interstitial fibrosis and, in the advanced stages, medullary cysts. SIMILARITY: Contains 6 TPR repeats. SIMILARITY: Contains 6 WD repeats. SEQUENCE CAUTION: Sequence=AAH32578.1; Type=Frameshift; Positions=421;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
