Previous GeneCards Identifiers for RTN4 Gene
This gene belongs to the family of reticulon encoding genes. Reticulons are associated with the endoplasmic reticulum, and are involved in neuroendocrine secretion or in membrane trafficking in neuroendocrine cells. The product of this gene is a potent neurite outgrowth inhibitor which may also help block the regeneration of the central nervous system in higher vertebrates. Alternatively spliced transcript variants derived both from differential splicing and differential promoter usage and encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
GeneCards Summary for RTN4 Gene
RTN4 (Reticulon 4) is a Protein Coding gene. Diseases associated with RTN4 include Demyelinating Disease and Oligodendroglioma. Among its related pathways are p75 NTR receptor-mediated signalling and Signaling by GPCR. GO annotations related to this gene include poly(A) RNA binding. An important paralog of this gene is RTN1.
UniProtKB/Swiss-Prot for RTN4 Gene
Developmental neurite growth regulatory factor with a role as a negative regulator of axon-axon adhesion and growth, and as a facilitator of neurite branching. Regulates neurite fasciculation, branching and extension in the developing nervous system. Involved in down-regulation of growth, stabilization of wiring and restriction of plasticity in the adult CNS. Regulates the radial migration of cortical neurons via an RTN4R-LINGO1 containing receptor complex (By similarity). Isoform 2 reduces the anti-apoptotic activity of Bcl-xl and Bcl-2. This is likely consecutive to their change in subcellular location, from the mitochondria to the endoplasmic reticulum, after binding and sequestration. Isoform 2 and isoform 3 inhibit BACE1 activity and amyloid precursor protein processing. Induces the formation and stabilization of endoplasmic reticulum (ER) tubules (PubMed:25612671, PubMed:24262037). Regulates membrane morphogenesis in the ER by promoting tubular ER production. Influences NE expansion, nuclear pore complex formation and proper localization of inner nuclear membrane proteins (PubMed:26906412).
