VNUT55 is expressed in mucin granules. A: Western blot illustrating VNUT55 immunoreactivity in fractions isolated after centrifugation of P2 on Percoll density gradients. B: VNUT immunoreactivity coeluted with the mucin granule-rich fraction, assessed by its MUC5AC content (fraction 4). C: ATP and UTP levels are concentrated in the VNUT55- and mucin granule-rich fraction 4.
