Protein attributes

Sequence length	365 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in the presentation of foreign antigens to the immune system.
Subunit structure	Heterodimer of an alpha chain and a beta chain (beta-2-microglobulin). Interacts with human herpesvirus 8 MIR1 protein By similarity.
Subcellular location	Membrane; Single-pass type I membrane protein.
Post-translational modification	Polyubiquitinated in a post ER compartment by interaction with human herpesvirus 8 MIR1 protein. This targets the protein for rapid degradation via the ubiquitin system By similarity.
Polymorphism	The following alleles of A-33 are known: A*33:01 (Aw-33.1), A*3302 and A*33:03. The sequence shown is that of A*33:01.
Sequence similarities	Belongs to the MHC class I family. Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
