This gene belongs to the HLA class I heavy chain paralogues. It encodes a non-classical heavy chain that forms a heterodimer with a beta-2 microglobulin light chain, with the heavy chain anchored in the membrane. Unlike most other HLA heavy chains, this molecule is localized in the endoplasmic reticulum and Golgi apparatus, with a small amount present at the cell surface in some cell types. It contains a divergent peptide-binding groove, and is thought to bind a restricted subset of peptides for immune presentation. This gene exhibits few polymorphisms. Multiple transcript variants encoding different isoforms have been found for this gene. These variants lack a coding exon found in transcripts from other HLA paralogues due to an altered splice acceptor site, resulting in a shorter cytoplasmic domain. [provided by RefSeq, Jul 2008]

Interaction

Forms a heterotrimer with B2M and a self-peptide (PubMed:28636952). Binds a diverse number of peptides ranging from 7 to more than 30 amino acids (PubMed:28636952). Peptide-bound HLA-F-B2M interacts with LILRB1 and LILRB2 but not with KIR3DS1 or KIR3DL2; this interaction is direct (PubMed:28636952, PubMed:11169396). The OC form interacts with KIR3DS1, KIR2DS4 and KIR3DL2; this interaction is direct (PubMed:28636952, PubMed:27455421, PubMed:24018270). Interacts with TAP1-TAP2 complex and CALR; this interaction is required for appropriate folding and peptide loading (PubMed:10605026, PubMed:11169396). Interacts with the coat protein complex II and 14-3-3 proteins; these interactions likely control the anterograde ER-to-Golgi transport of HLA-F (PubMed:16709803). HLA-F-B2M complex interacts with the heavy chain of other MHC class I molecules including HLA-A and HLA-E; this interaction may regulate the intracellular trafficking and the stability of peptide-free MHC class I OCs (PubMed:20483783).
