Abcb9 - ATP binding cassette subfamily B member 9

Predicted to enable several functions, including ABC-type peptide transporter activity; ATP binding activity; and TAP1 binding activity. Predicted to contribute to MHC class I protein binding activity. Predicted to be involved in several processes, including antigen processing and presentation of endogenous peptide antigen via MHC class I; peptide metabolic process; and peptide transport. Predicted to be located in endoplasmic reticulum membrane and lysosomal membrane. Predicted to be integral component of endoplasmic reticulum membrane. Predicted to be part of MHC class I peptide loading complex. Predicted to be integral component of membrane. Orthologous to human ABCB9 (ATP binding cassette subfamily B member 9).
