  • basic FUNCTION
  • palmitoyl acyltransferase
  • stimulates palmitoylation of tetraspanins CD9 and CD151
  • ZDHHC2-dependent palmitoylation had multiple functional effects, promoting physical associations between CD9 and CD151, and between alpha3 integrin and other proteins
  • important role for DHHC2-mediated palmitoylation of CKAP4 in opposing cancer-related cellular behaviors, supporting the idea that DHHC2 is a tumor suppressor
  • with ZDHHC3, are differentially regulated and dynamic recruitment of protein palmitoylation machinery enables compartmentalized regulation of protein trafficking in response to extracellular signals
  • candidate enzyme to regulate SNAP25/23 palmitoylation dynamics at the plasma membrane
  • mediates de novo and turnover palmitoylation of R7BP (
  • localizes to dendritic vesicles of unknown origin in neurons, where it regulates dynamic palmitoylation of DLG4
  • capable of palmitoylating of Lck in T cells (

  • Reducing the DHHC2 level in Jurkat T cells using siRNA causes decreased Lck S-acylation and partial dislocation from membranes, and conversely overexpression of DHHC2 increases S-acylation of an Lck surrogate, LckN10-GFP (
