Genes affected

SLCO1B3-SLCO1B7 (HGNC:54403): (SLCO1B3-SLCO1B7 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring SLCO1B3 (solute carrier organic anion transporter family member 1B3) and SLCO1B7 (solute carrier organic anion transporter family member 1B7 (putative)) genes on chromosome 12. The readthrough transcript encodes a protein that shares sequence identity with both the upstream and downstream genes. [provided by RefSeq, Jun 2019]

LOC124902894 (HGNC:):

SLCO1B7 (HGNC:32934): (solute carrier organic anion transporter family member 1B7 (putative)) Predicted to enable bile acid transmembrane transporter activity and sodium-independent organic anion transmembrane transporter activity. Predicted to be involved in bile acid and bile salt transport and sodium-independent organic anion transport. Predicted to be integral component of plasma membrane.
