Coordination of murine parotid secretory protein and salivary amylase expression.
PSP, parotid secretory protein, and salivary amylase are the major secretory proteins of mouse parotid gland where they appear in a constant ratio. Here we describe the isolation of the PSP gene and show through expression analysis on this and the salivary amylase gene that the two genes are transcribed in a coordinate fashion in adult animals, whereas the activation profiles are different during postnatal development. An explanation is put forward that involves activation of the genes at different stages of the acinar cell differentiation, leading in adults to the maximal and thus proportionate expression.
