General annotation (Comments)

Function	Chaperone specifically assisting the folding of beta-propeller/EGF modules within the family of low-density lipoprotein receptors (LDLRs). Acts as a modulator of the Wnt pathway through chaperoning the coreceptors of the canonical Wnt pathway, LRP5 and LRP6, to the plasma membrane. Essential for specification of embryonic polarity and mesoderm induction. Ref.7 Ref.8
Subunit structure	Monomer By similarity. Interacts with LRP5; the interaction prevents LRP5 from forming aggregates and chaperones LRP6 to the plasma membrane. Interacts with LRP6; the interaction prevents LRP6 from forming aggregates and chaperones LRP6 to the plasma membrane. Ref.8
Subcellular location	Endoplasmic reticulum Ref.7 Ref.8.
Domain	The chaperone domain provides a folding template for proper folding of the beta-propeller (BP) domains of LRP5/6 By similarity. The escort domain ensures LRP5/6 safe-trafficking from the ER to the Golgi by preventing premature ligand-binding By similarity.
Sequence similarities	Belongs to the MESD family.
Sequence caution	The sequence BAA07640.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
