1 In the present study, 35SO4 was shown to be incorporated into SP-I and several other proteins of porcine parathyroid tissue incubated in vitro. 35so4 chromogranin A Homo sapiens
2 Up to 20% of the tyrosine residues in secreted SP-I were labeled with 35SO4. 35so4 chromogranin A Homo sapiens
3 Extracellular Ca2+ (3 mM) greatly suppressed the secretion of 35SO4-labeled SP-I without affecting the intracellular sulfation of the molecule or the secretion of a minor sulfated protein unrelated to SP-I. 35so4 chromogranin A Homo sapiens
4 The ratio of incorporated 35SO4 to 3H-amino-acid was greater in secreted SP-I than in tissue SP-I, suggesting that much sulfation of this protein occurred during or just before secretion. 35so4 chromogranin A Homo sapiens
