  • FunctionInvolved in the association of MHC class I with transporter associated with antigen processing (TAP) and in the assembly of MHC class I with peptide (peptide loading).
  • Tissue specificityNeutrophils, mostly in fully differentiated cells.
  • Sequence similaritiesContains 1 Ig-like C1-type (immunoglobulin-like) domain.
  • DomainThe N-terminus is required for efficient association with MHC class I molecule and for a stable interaction between MHC I and calreticulin. Binding to TAP is mediated by the C-terminus region.
  • Cellular localizationEndoplasmic reticulum membrane.
