Gene: TAPBP (TAP binding protein) Homo sapiens
Symbol: TAPBP
Name: TAP binding protein
Description: Exhibits TAP complex binding activity; TAP1 binding activity; and TAP2 binding activity. Involved in MHC class Ib protein complex assembly; regulation of gene expression; and regulation of protein complex stability. Localizes to Golgi membrane and MHC class I peptide loading complex. Implicated in MHC class I deficiency and severe combined immunodeficiency.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: NGS-17; NGS17; TAP binding protein (tapasin); TAP-associated protein; TAP-binding protein; TAPA; tapasin; TPN; TPSN
