General Information
| EC Number | General Information | Comment | Organism |
|---|---|---|---|
| 2.8.2.1 | metabolism | isoform SULT4A1 interacts with both SULT1A1 and SULT1A3 when expressed in human cells. SULT4A1, SULT1A1, and SULT1A3 proteins form homodimers and heterodimers that require the sulfotransferase dimerization motif. A loss in SULT1A1/3 protein but an increase in SULT4A1 protein is observed during differentiation of neuronal SH-SY5Y cells, resulting in an increase in the toxicity of substrate dopamine | Homo sapiens |
