Post Translational Modifications | Phosphorylated, leading to STXBP5L increased turnover and subsequent de-repression of insulin secretion. Phosphorylated on serine residues in response to glucose or phorbol esters. Ubiquitinated by the E3 ligase SYVN1, leading to STXBP5L proteasomal degradation. |
Function | Plays a role in vesicle trafficking and exocytosis inhibition. In pancreatic beta-cells, inhibits insulin secretion probably by interacting with and regulating STX1A and STX4, key t-SNARE proteins involved in the fusion of insulin granules to the plasma membrane. Also plays a role in neurotransmitter release by inhibiting basal acetylcholine release from axon terminals and by preventing synaptic fatigue upon repetitive stimulation. Promotes as well axonal outgrowth. |
