Corticotropin releasing factor stimulation of protein carboxylmethylation in mouse pituitary tumor cells.


A putative role for the protein carboxylmethylase (PCM) enzyme has been suggested in exocytotic secretion. The involvement of 3H-methyl incorporation into protein carboxylmethyl esters during corticotropin releasing factor (CRF)-induced ACTH secretion from AtT-20/D16-16 mouse pituitary cells was investigated. Protein carboxylmethylation and ACTH secretion… (More)
