BRINP1, or BMP/retinoic acid-inducible neural-specific protein 1, is a member of the BRINP protein family. It is mainly expressed in the brain and plays crucial roles in neuronal functions such as neurodevelopment, synaptic plasticity, and neuronal survival. BRINP1 is induced by factors like bone morphogenetic proteins (BMPs) and retinoic acid during early neural development, indicating its role in the patterning and differentiation of neural progenitor cells. Its expression is precisely regulated both spatially and temporally in the developing brain, underscoring its essential role in neural maturation and function.
