Genes affected

SULT1A4 (HGNC:30004): (sulfotransferase family 1A member 4) Sulfotransferase enzymes catalyze the sulfate conjugation of many hormones, neurotransmitters, drugs, and xenobiotic compounds. These cytosolic enzymes are different in their tissue distributions and substrate specificities. The gene structure (number and length of exons) is similar among family members. This gene encodes a phenol sulfotransferase with thermolabile enzyme activity. Four sulfotransferase genes are located on the p arm of chromosome 16, this gene and SULT1A3 arose from a segmental duplication. Read-through transcription exists between this gene and the upstream SLX1B (SLX1 structure-specific endonuclease subunit homolog B) gene that encodes a protein containing GIY-YIG domains.

SLX1B-SULT1A4 (HGNC:48353): (SLX1B-SULT1A4 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring SLX1B (SLX1 structure-specific endonuclease subunit homolog B) and SULT1A4 (sulfotransferase family, cytosolic, 1A, phenol-preferring, member 4) genes on the short arm of chromosome 16. A duplicate read-through locus also exists between the SLX1A and SULT1A3 genes located approximately 730 kb downstream on the same chromosome. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2017]
