Arh Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
ARH (Autosomal Recessive Hypercholesterolemia), also known as LDLRAP1, encodes an adaptor protein that facilitates LDL receptor-mediated endocytosis. While primarily studied in the context of lipid metabolism, ARH has been implicated in neuronal cholesterol homeostasis and may play roles in neurodegenerative diseases through effects on membrane lipid composition and synaptic function.

ARH (Autophagy Receptor Homolog) is a gene that encodes an autophagy receptor protein involved in selective autophagy pathways. The ARH protein (also known as LDLRAP1) functions as an adaptor protein that links cargo to the autophagy machinery.
ARH plays a role in neuronal autophagy and has been implicated in neurodegenerative diseases through its involvement in protein aggregate clearance and cellular homeostasis.
ARH encodes an adaptor protein that links the LDL receptor (LDLR) to clathrin-mediated endocytosis. ARH contains an N-terminal phosphotyrosine-binding (PTB) domain that recognizes the NPXY motif in the cytoplasmic tail of LDLR. It also interacts with clathrin and AP-2, facilitating receptor internalization.
High expression in liver and brain.
