Protein

Sulfotransferase 1A4

Gene

SULT1A4

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic monoamines (neurotransmitters such as dopamine, norepinephrine and serotonin) and phenolic and catechol drugs.

Caution

Found in a segmental duplication on p arm of chromosome 16 giving rise to two identical copies of this gene sharing exons with SLX1A and SLX1B. The ORFs of SULT1A3 and SULT1A4 differ with only a single nucleotide change that does not alter the encoded amino acid. It is not possible to determine whether any individual polymorphism is present within SULT1A3 or SULT1A4 (PubMed:15358107).1 Publication

Catalytic activityi

3'-phosphoadenylyl sulfate + a phenol = adenosine 3',5'-bisphosphate + an aryl sulfate.
