Protein attributes

Sequence length	4599 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Potential cell surface proteins that bind and internalize ligands in the process of receptor-mediated endocytosis.
Subunit structure	Binds LRPAP1, PLAU, PLAT and SERPINE1; binding is followed by internalization and degradation of the ligands.
Subcellular location	Membrane; Single-pass type I membrane protein Potential.
Tissue specificity	Expressed in thyroid gland and in salivary gland, as well as in adult and fetal brain. Ref.3
Miscellaneous	The gene is preferentially inactivated in one histological type of lung cancer (non-small cell lung cancer (NSCLC)). May thus play an important role in tumorigenesis of NSCLCs.
Sequence similarities	Belongs to the LDLR family. Contains 14 EGF-like domains. Contains 32 LDL-receptor class A domains. Contains 36 LDL-receptor class B repeats.
