ADAM23, belonging to ADAM (A Disintegrin And Metalloprotease) protein family, is mainly expressed in brain. P19 cells could differentiate into neuroectodermal cell lineage after cell aggregates have been induced by retinoic acid (RA). In this report, we show that the post-transcriptional and post-translational processes of ADAM23 are regulated during the differentiation of P19 cells. In P19-derived neurons, ADAM23 is polarized distributed in the proximal part. To explore the possible roles of ADAM23 during P19 cell neuronal differentiation, ADAM23-RNAi P19 cell lines were established. These transfected cells could differentiate into neurofilament-expression neurons in the absence of RA, whereas wild-type P19 cell can not. These results suggest ADAM23 may play roles in both early and later stage of neuronal differentiation.
