background:
Aladin (Adracalin) belongs to a family of WD repeat-containing proteins. These proteins have a wide variety of functions, including signal transduction regulation, RNA processing and transcription. Aladin plays a role in peripheral and central nervous system development. It is widely expressed, with the highest expression seen in pituitary gland, corpus callosum, cerebellum, adrenal gland and gastrointestinal structures. Defects in Aladin cause the autosomal recessive disorder achalasia-addisonianism-alacrima (triple A) syndrome. Triple A syndrome is characterized by achalasia, alacrima and adrenocortico-tropin-resistant adrenal insufficiency. Robust expression in neural systems associated with cognitive, motor and sensory functions is consistent with the myriad of symptoms experienced by patients with triple A syndrome.
Function:
Adracalin (AAAS) is expressed in both neuroendocrine and cerebral structures and may function in the normal development of the peripheral and central nervous system. It localizes to nuclear pore complexes (NPCs), large multiprotein assemblies that are the sole sites of nucleocytoplasmic transport. Defects in AAAS are the cause of achalasia-addisonianism-alacrima syndrome (AAA syndrome); also known as triple-A syndrome or Allgrove syndrome.
Subcellular Location:
nuclear pore
Tissue Specificity:
Widely expressed. Particularly abundant expression is found in cerebellum, corpus callosum, adrenal gland, pituitary gland, gastrointestinal structures and fetal lung.
DISEASE:
Defects in AAAS are the cause of achalasia-addisonianism-alacrima syndrome (AAAS) [MIM:231550]; also known as triple-A syndrome or Allgrove syndrome. AAAS is an autosomal recessive disorder characterized by adreno-corticotropic hormone (ACTH)-resistant adrenal failure, achalasia of the esophageal cardia and alacrima. The syndrome is associated with variable and progressive neurological impairment involving the central, peripheral, and autonomic nervous system. Other features such as palmoplantar hyperkeratosis, short stature, facial dysmorphy and osteoporosis may also be present.
Similarity:
Contains 4 WD repeats.
