Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May play a positive role in AHR-mediated (aromatic hydrocarbon receptor) signaling, possibly by influencing its receptivity for ligand and/or its nuclear targeting. Cellular negative regulator of the hepatitis B virus (HBV) X protein.
Subcellular location	Cytoplasm.
Tissue specificity	Widely expressed. Higher levels seen in the heart, placenta and skeletal muscle. Not expressed in the liver.
Involvement in disease	Defects in AIP are a cause of pituitary adenoma predisposition (PAP) [MIM:102200]. Pituitary adenomas include somatotropinoma and prolactinoma. Ref.8 Defects in AIP are a cause of familial isolated pituitary adenoma (FIPA) [MIM:102200]. Ref.4 Defects in AIP are a cause of growth hormone-secreting pituitary adenoma [MIM:102200]; also known as familial isolated somatotropinomas (FIS) or isolated familial somatotropinoma (IFS) or familial somatotrophinoma or acromegaly due to pituitary adenoma. Defects in AIP are a cause of ACTH-secreting pituitary adenoma [MIM:219090]; also known as pituitary Cushing disease. Cushing disease is a condition associated with increased blood cortisol resulting from adrenocorticotropic hormone (ACTH)-producing pituitary tumors that are resistant to glucocorticoid negative feedback. Ref.11 Defects in AIP are a cause of prolactin-secreting pituitary adenoma [MIM:600634]; also known as prolactinoma. Prolactin-secreting pituitary adenoma is the most common type of hormonally active pituitary adenoma.
Sequence similarities	Contains 1 PPIase FKBP-type domain. Contains 2 TPR repeats.
