Function

[HA1T_MOUSE] Involved in the presentation of foreign antigens to the immune system. [CD8A_MOUSE] Identifies cytotoxic/suppressor T-cells that interact with MHC class I bearing targets. CD8 is thought to play a role in the process of T-cell mediated killing. CD8 alpha chains binds to class I MHC molecules alpha-3 domains. [B2MG_MOUSE] Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system.

Publication Abstract from PubMed

TL is a nonclassical MHC class I molecule that modulates T cell activation through relatively high-affinity interaction with CD8alphaalpha. To investigate how the TL/CD8alphaalpha interaction influences TCR signaling, we characterized the structure of the TL/CD8alphaalpha complex using X-ray crystallography. Unlike antigen-presenting molecules, the TL antigen-binding groove is occluded by specific conformational changes. This feature eliminates antigen presentation, severely hampers direct TCR recognition, and prevents TL from participating in the TCR activation complex. At the same time, the TL/CD8alphaalpha interaction is strengthened through subtle structure changes in the TL alpha3 domain. Thus, TL functions to sequester and redirect CD8alphaalpha away from the TCR, modifying lck-dependent signaling.
