VLDLR Summary & Protein Information

VLDLR Background

Gene Summary: The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. VLDLR gene encodes a lipoprotein receptor that is a member of the LDLR family and plays important roles in VLDL-triglyceride metabolism and the reelin signaling pathway. Mutations in VLDLR gene cause VLDLR-associated cerebellar hypoplasia. Alternative splicing generates multiple transcript variants encoding distinct isoforms for VLDLR gene.

General information above from NCBI
Subunit structure: Binds to the extracellular matrix protein Reelin. Interacts with VLDLR. Interacts with SNX17 (By similarity). Interacts with DAB1. Receptor for the minor-group human rhinoviruses (HRVs); binds protein VP1 through the second and third LDL-receptor class A domains. Interacts with PCSK9.
Subcellular location: Membrane; Single-pass type I membrane protein. Membrane, clathrin-coated pit; Single-pass type I membrane protein.
Tissue specificity: Abundant in heart and skeletal muscle; also ovary and kidney; not in liver.
Post-translational: Ubiquitinated at Lys-839 by MYLIP leading to degradation.
Involvement in disease: Cerebellar ataxia, mental retardation, and dysequilibrium syndrome 1 (CAMRQ1) [MIM:224050]: A congenital, non-progressive cerebellar ataxia associated with disturbed equilibrium, delayed ambulation, mental retardation, cerebellar hypoplasia and mild cerebral gyral simplification. Additional features include short stature, strabismus, pes planus and, rarely, seizures. Note=The disease is caused by mutations affecting the gene represented in this entry.
Sequence similarity: Contains 3 EGF-like domains.
Contains 8 LDL-receptor class A domains.
Contains 6 LDL-receptor class B repeats.
General information above from UniProt

The very low density lipoprotein receptor, known as VLDLR, is a single-pass type 1 integral membrance protein and a member of the LDL receptor family. This receptor family includes LDL receptor, LRP, megalin, VLDLR and ApoER2, and is characterized by a cluster of cysteine-rich class A repeats, epidermal growth factor (EGF)-like repeats, YWTD repeats and an O-linked sugar domain. VLDLR contains 3 EGF-like domains, 8 LDL-receptor class A domains, as well as 6 LDL-receptor class B repeats, and is abundant in heart, skeletal muscle, also ovary and kidney, but not in liver. VLDLR binds VLDL and transports it into cells by endocytosis. In order to be internalized, the receptor-ligand complexes must first cluster into clathrin-coated pits. VLDLR mediates the phosphorylation of mDab1 (mammalian disabled protein) via binding to Reelin, and induces the modulation of Tau phosphorylation. This pathway regulates the migration of neurons along the radial glial fiber network during brain development. Defects of VLDLR may be the cause of VLDLR-associated cerebellar hypoplasia (VLDLRCH), a syndrome characterized by moderate-to-profound mental retardation, delayed ambulation, and predominantly truncal ataxia.
