Previous GeneCards Identifiers for TAPBPL Gene
Tapasin, or TAPBP (MIM 601962), is a member of the variable-constant Ig superfamily that links major histocompatibility complex (MHC) class I molecules to the transporter associated with antigen processing (TAP; see MIM 170260) in the endoplasmic reticulum (ER). The TAPBP gene is located near the MHC complex on chromosome 6p21.3. TAPBPL is a member of the Ig superfamily that is localized on chromosome 12p13.3, a region somewhat paralogous to the MHC.[supplied by OMIM, Mar 2008]
GeneCards Summary for TAPBPL Gene
TAPBPL (TAP Binding Protein-Like) is a Protein Coding gene. GO annotations related to this gene include protein complex binding. An important paralog of this gene is TAPBP.
UniProtKB/Swiss-Prot for TAPBPL Gene
Component of the antigen processing and presentation pathway, which binds to MHC class I coupled with beta2-microglobulin/B2M. Association between TAPBPR and MHC class I occurs in the absence of a functional peptide-loading complex (PLC). Expression seems to slow down and down-regulate MHC class I surface expression.
