Functioni

Component of the ERLIN1/ERLIN2 complex which mediates the endoplasmic reticulum-associated degradation (ERAD) of inositol 1,4,5-trisphosphate receptors (IP3Rs). Involved in regulation of cellular cholesterol homeostasis by regulation the SREBP signaling pathway. Binds cholesterol and may promote ER retention of the SCAP-SREBF complex (PubMed:24217618).2 Publications

Caution

This sequence contains two in frame methionine codon situated in atypical consensus Kozak sequence in the 5'terminus. By homolog comparison, the second ATG was supposed to be the start codon according to PubMed:11118313.Curated

Involvement in diseasei

Spastic paraplegia 62, autosomal recessive (SPG62)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body.
