The Synaptojanins in the murine small and large intestine.

The expression of the phosphoinositides phosphatases Synaptojanins (Synjs) 1 and 2 has been shown in brain and in some peripheral tissues, but their expression in the intestine has not been reported. Herein we show that the small and large intestine express Synj1 and Synj2. Their mRNA levels, measured by RT-PCR, are not affected by development in the small intestine but in the colon they increase with age.
