Antigen-presenting major histocompatibility complex class I (MHCI) molecule with an important role in reproduction and antiviral immunity (PubMed:20972337, PubMed:24091323, PubMed:20439706, PubMed:11172028, PubMed:20104487, PubMed:28649982, PubMed:29312307). In complex with B2M/beta 2 microglobulin displays a restricted repertoire of self and viral peptides and acts as a dominant ligand for inhibitory and activating killer immunoglobulin receptors (KIRs) expressed on NK cells (PubMed:16141329). In an allogeneic setting, such as during pregnancy, mediates interaction of extravillous trophoblasts with KIR on uterine NK cells and regulate trophoblast invasion necessary for placentation and overall fetal growth (PubMed:20972337, PubMed:24091323). During viral infection, may present viral peptides with low affinity for KIRs, impeding KIR-mediated inhibition through peptide antagonism and favoring lysis of infected cells (PubMed:20439706). Presents a restricted repertoire of viral peptides on antigen-presenting cells for recognition by alpha-beta T cell receptor (TCR) on HLA-C-restricted CD8-positive T cells, guiding antigen-specific T cell immune response to eliminate infected cells, particularly in chronic viral infection settings such as HIV-1 or CMV infection (PubMed:11172028, PubMed:20104487, PubMed:28649982). Both the peptide and the MHC molecule are recognized by TCR, the peptide is responsible for the fine specificity of antigen recognition and MHC residues account for the MHC restriction of T cells (By similarity). Typically presents intracellular peptide antigens of 9 amino acids that arise from cytosolic proteolysis via proteasome. Can bind different peptides containing allele-specific binding motifs, which are mainly defined by anchor residues at position 2 and 9. Preferentially displays peptides having a restricted repertoire of hydrophobic or aromatic amino acids (Phe, Ile, Leu, Met, Val and Tyr) at the C-terminal anchor (PubMed:8265661, PubMed:25311805).By similarity

Heterotrimer that consists of an alpha chain HLA-C, a beta chain B2M and a peptide (peptide-HLA-C-B2M) (PubMed:28649982, PubMed:10850706, PubMed:24990997). Early in biogenesis, HLA-C-B2M dimer interacts with the components of the peptide-loading complex composed of TAPBP, TAP1-TAP2, TAPBPL, PDIA3/ERP57 and CALR (PubMed:18420581).
Interacts with TAP1-TAP2 transporter via TAPBP; this interaction is obligatory for the loading of peptide epitopes delivered to the endoplasmic reticulum (ER) by TAP1-TAP2 transporter (By similarity). Being very selective in the peptide binding, forms a stable interaction with TAP1-TAP2, often leading to the accumulation of free heavy chains in the ER (PubMed:18420581). Only optimally assembled peptide-HLA-C-B2M trimer translocates to the surface of antigen-presenting cells, where it interacts with TCR and CD8 coreceptor on the surface of T cells. HLA-C (via polymorphic alpha-1 and alpha-2 domains) interacts with antigen-specific TCR (via CDR3 domains) (By similarity). One HLA-C molecule (mainly via nonpolymorphic alpha-3 domain) interacts with one CD8A homodimer (via CDR-like loop); this interaction insures peptide-HLA-C-B2M recognition by CD8-positive T cells only (By similarity). The peptide-HLA-C-B2M complex also interacts with KIRs. HLA-C type 1 (C1, with Asn104), including HLA-C*02, C*04, C*05, C*06 and C*15, interact with KIR2DL1 and KIR2DS1, and HLA-C type 2 (C2, with Lys104), including HLA-C*01, C*03, C*07 and C*08, interact with KIR2DL2 and KIR2DL3 (PubMed:20972337, PubMed:24091323, PubMed:16141329, PubMed:20439706, PubMed:11323700, PubMed:10850706).

<p>The checksum is a form of redundancy check that is calculated
from the sequence. It is useful for tracking sequence updates.</p>
<p>It should be noted that while, in theory, two different sequences could
have the same checksum value, the likelihood that this would happen
is extremely low.</p>
<p>However UniProtKB may contain entries with identical sequences in case
of multiple genes (paralogs).</p>
<p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64)
using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
The algorithm is described in the ISO 3309 standard.

Displays lower polymorphism than HLA-A and HLA-B. Polymorphic residues encode for alpha-1 and alpha-2 domains of the peptide-binding cleft, where they contribute to variations in peptide binding and TCR recognition among different alleles. The human population is estimated to have millions of HLA-C alleles. But only 14 common HLA-C alleles are considered core alleles, representing all functionally significant variation (polymorphism) in alpha-1 and alpha-2 domains. These are: C*01:02; C*02:02; C*03:02; C*04:01; C*05:01; C*06:02; C*07:01; C*07:04; C*08:01; C*12:02; C*14:02; C*15:02; C*16:01 and C*17:01. Among these, C*01:02; C*02:02; C*03:02; C*08:01; C*12:02; C*14:02 and C*15:02, were likely passed by introgression from archaic to modern humans. Functional alleles of more recent origin (non-core) were derived by recombination (PubMed:28650991). The sequence shown is that of C*07:02. The sequences of core alleles and common representative alleles of serologically distinct allele groups are described as variants of C*07:02.Curated1 Publication
