Summaries for ITSN2 Gene

Entrez Gene Summary for ITSN2 Gene

  • This gene encodes a cytoplasmic protein which contains SH3 domains. This protein is a member of a family of proteins involved in clathrin-mediated endocytosis. Intersectin 2 is thought to regulate the formation of clathrin-coated vesicles and also may function in the induction of T cell antigen receptor (TCR) endocytosis. Alternatively spliced transcript variants have been found for this gene that encode three distinct isoforms. Additional variants have been found but their full length nature has not been determined.

GeneCards Summary for ITSN2 Gene

ITSN2 (Intersectin 2) is a Protein Coding gene. Among its related pathways are Regulation of CDC42 activity and EphB-EphrinB Signaling. GO annotations related to this gene include calcium ion binding and Rho guanyl-nucleotide exchange factor activity. An important paralog of this gene is EHD1.

UniProtKB/Swiss-Prot for ITSN2 Gene

  • Adapter protein that may provide indirect link between the endocytic membrane traffic and the actin assembly machinery. May regulate the formation of clathrin-coated vesicles (CCPs). Seems to be involved in CCPs maturation including invagination or budding. Involved in endocytosis of integrin beta-1 (ITGB1) and transferrin receptor (TFR).
