    text
  • nuclear relocation of dendrin in response to glomerular injury promotes podocyte apoptosis
  • basic FUNCTION
  • a putative modulator of the postsynaptic cytoskeleton
  • slit diaphragms protein with proapoptotic signaling properties that accumulates in the podocyte nucleus in response to glomerular injury
  • acting as an enhancer of apoptosis
  • its expression during glomerulogenesis and in the normal human kidney is similar to that previously shown for nephrin, which suggests that dendrin associates with the slit diaphragm complex
  • is an important component of cytoskeletal modifications at the synapse
  • having a a surveillance function at the slit diaphragms and relocates to the podocyte nucleus in response to glomerular injury, thereby providing a signaling mechanism whereby changes in slit diaphragms function modulate podocyte survival
  • dual compartment protein with proapoptotic signaling properties

    protein
  • binds directly to nephrin and CD2AP, by its C-terminus
  • YAP1 binding to dendrin is a prosurvival mechanism
  • dendrin binds to WTIP and GADD45A (WTIP and GADD45A mediate gene transcription in the nucleus, suggesting that dendrin may have similar functions in podocytes
  • DDN is phosphorylated by FYN and dephosphorylated by PTPN1, and FYN-induced phosphorylation prevents NEDD4L-mediated ubiquitination of dendrin
  • MAGI2 and FYN protect DDN from NEDD4L-mediated ubiquitination and from nuclear translocation, thereby maintaining the physiologic homeostasis of podocytes, and the lack of MAGI2 in podocytes results in glomerulosclerosis
