Summaries for STX8 Gene

Entrez Gene Summary for STX8 Gene

  • The gene is a member of the syntaxin family. The encoded protein is involved in protein trafficking from early to late endosomes via vesicle fusion and exocytosis. A related pseudogene has been identified on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

GeneCards Summary for STX8 Gene

STX8 (Syntaxin 8) is a Protein Coding gene. Diseases associated with STX8 include Neuronal Ceroid Lipofuscinosis. Among its related pathways are wtCFTR and delta508-CFTR traffic / Generic schema (norm and CF) and wtCFTR and deltaF508 traffic / Late endosome and Lysosome (norm and CF). GO annotations related to this gene include ubiquitin protein ligase binding and SNAP receptor activity.

UniProtKB/Swiss-Prot for STX8 Gene

  • Vesicle trafficking protein that functions in the early secretory pathway, possibly by mediating retrograde transport from cis-Golgi membranes to the ER.
