This gene encodes a member of the SPFH domain-containing family of lipid raft-associated proteins. The encoded protein is localized to lipid rafts of the endoplasmic reticulum and plays a critical role in inositol 1,4,5-trisphosphate (IP3) signaling by mediating ER-associated degradation of activated IP3 receptors. Mutations in this gene are a cause of spastic paraplegia-18 (SPG18). Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

GeneCards Summary for ERLIN2 Gene
ERLIN2 (ER Lipid Raft Associated 2) is a Protein Coding gene. Diseases associated with ERLIN2 include Spastic Paraplegia 18, Autosomal Recessive and Spastic Paraplegia 18. Among its related pathways are Cytoskeletal Signaling and HIV Life Cycle. An important paralog of this gene is ERLIN1.
UniProtKB/Swiss-Prot for ERLIN2 Gene
Component of the ERLIN1/ERLIN2 complex which mediates the endoplasmic reticulum-associated degradation (ERAD) of inositol 1,4,5-trisphosphate receptors (IP3Rs) such as ITPR1 (PubMed:19240031, PubMed:17502376). Promotes sterol-accelerated ERAD of HMGCR probably implicating an AMFR/gp78-containing ubiquitin ligase complex (PubMed:21343306). Involved in regulation of cellular cholesterol homeostasis by regulation the SREBP signaling pathway. May promote ER retention of the SCAP-SREBF complex (PubMed:24217618).
