Abstract

Human genome studies have suggested that strawberry notch homologue 1 (SBNO1) is crucial for normal brain development, with mutations potentially contributing to neurodevelopmental disorders. In a previous study, we observed significant developmental abnormalities in the neocortex of Sbno1 as early as one week after birth. In the present study, we conducted an extensive analysis of Sbno1 postnatal expression in the brain of C57BL/6 mice using a newly developed in-house polyclonal antibody against Sbno1. We found that Sbno1 is expressed in all neurons, with certain neuronal populations exhibiting distinct dynamic changes (both temporal and spatial) in expression level. These findings suggest that the neuronal expression of Sbno1 is developmentally regulated after birth. They also indicate that while Sbno1 may play a general role across all neurons, it may also serve more specialized functions in certain neuronal types and/or for certain cellular activities related to particular neuronal pathways.
