General annotation (Comments)

Function	Cochaperone that stimulates HSP90 ATPase activity By similarity. May affect a step in the endoplasmic reticulum to Golgi trafficking.
Subunit structure	Interacts with HSPCA/HSP90 and with the cytoplasmic tail of the vesicular stomatitis virus glycoprotein (VSV G). Interacts with GCH1. Interacts with SRPK1. Ref.8 Ref.9 Ref.10 Ref.11 Ref.12
Subcellular location	Cytoplasm › cytosol. Endoplasmic reticulum. Note: May transiently interact with the endoplasmic reticulum. Ref.8
Tissue specificity	Expressed in numerous tissues, including brain, heart, skeletal muscle and kidney and, at lower levels, liver and placenta. Ref.8
Induction	By heat shock and treatment with the HSP90 inhibitor 17-demethoxygeldanamycin (17AAG). Ref.9
Sequence similarities	Belongs to the AHA1 family.
