Aldolase has also been implicated in many "moonlighting" or non-catalytic functions, based upon its binding affinity for multiple other proteins including F-actin, α-tubulin, light chain dynein, WASP, Band 3 anion exchanger, phospholipase D (PLD2), glucose transporter GLUT4, inositol trisphosphate, V-ATPase and ARNO (a guanine nucleotide exchange factor of ARF6).
the activation of phospholipase C by GPCR or RTK, which leads to the production of inositol trisphosphate, which in turn activates the InsP3 receptor.
