General Information | Comment | Organism |

malfunction | abnormalities in perineuronal nets and behavior are observed in mice lacking CSGalNAcT1. Loss of this enzyme reduces the amount of chondroitin sulfate (CS) by approximately 50% in various brain regions. The amount of CS in perineuronal nets (PNNs) is also diminished in T1KO compared to wild-type mice, although the amount of a major CS proteoglycan core protein, aggrecan, is not changed. In T1KO, abnormalities in several behavioral tests, including the open-field test, acoustic startle response, and social preference are observed. Phenotype, overview | Mus musculus |
metabolism | CSGalNAcT1 is a key enzyme in chondroitin sulfate synthesis. Chondroitin sulfate (CS) is an important glycosaminoglycan and is mainly found in the extracellular matrix as CS proteoglycans. In the brain, CS proteoglycans are highly concentrated in perineuronal nets (PNNs), which surround synapses and modulate their functions | Mus musculus |
physiological function | enzyme CSGalNAcT1 is important for plasticity, probably due to regulation of CS-dependent perineuronal nets (PNNs). It plays an important role in supplying CS for PNN development and brain functions related to several characteristic behaviors | Mus musculus |
