Members of the ProSAP/Shank family are important scaffolding proteins of the postsynaptic density (PSD). We investigated for the first time the expression of the three family members named Shank1, ProSAP1/Shank2, and ProSAP2/Shank3 during Xenopus laevis development. Shank1 is expressed in the neural tube, the retina, and the cranial ganglions. In contrast, ProSAP1/Shank2 transcripts could be visualized in the otic vesicle, the pronephros, the liver, the neural tube, and the retina. ProSAP2/Shank3 could be detected in the cardiovascular network, the neural tube, the pronephros, and the retina. Furthermore, we showed that LAPSER1 interacts with all three ProSAP/Shank family members in Xenopus embryos and co‐localizes with ProSAP/Shank in a cell‐based assay. In Xenopus , LAPSER1 is expressed in somites, brain, proctodeum, pronephros, and in some cranial ganglions. Thus, we suggest that members of the ProSAP/Shank family and LAPSER1 not only play a role in PSD formation and plasticity, but also during embryonic development.
