Protein attributes

Sequence length	60 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Participates in viral evasion from HLA class I-restricted T-cell immunity. Associates with host TAP1 and TAP2 and prevents TAP-mediated peptide transport and subsequent loading.
Subunit structure	Interacts with host TAP1 and TAP2 By similarity.
Subcellular location	Host endoplasmic reticulum membrane; Single-pass membrane protein Potential.
Sequence similarities	Belongs to the lymphocryptovirus BNLF2a family.
