Supplementary information

CD48 also known as SLAMF2 or B-lymphocyte activation marker BLAST-1 is a glycosylphosphatidylinositol (GPI)-anchored protein with a molecular mass approximately 45-70 kDa depending on glycosylation. It is expressed on the surface of various immune cells like T cells B cells and natural killer (NK) cells. CD48 does not possess an intracellular signaling domain but engages in extracellular interactions with other proteins affecting immune cell activities.
Biological function summary

CD48 serves as a co-stimulatory molecule involved in immune response modulation. It interacts with 2B4 (CD244) a member of the signaling lymphocyte activation molecule (SLAM) family to form a receptor-ligand complex. This interaction can result in enhanced T cell and NK cell responses. CD48's presence on activated hematopoietic and non-hematopoietic cells highlights its role in cell-to-cell communication.

Pathways

CD48 participates in SLAM family receptor signaling and natural killer cell-mediated cytotoxicity. In the SLAM pathway CD48 enhances communication and regulation between T cells and NK cells. This communication also relates to the roles of CD244 linking it to downstream signaling pathways that influence immune cell function. These pathways illustrate the critical network CD48 is part of which impacts various immune responses.

CD48 is involved in autoimmune conditions like rheumatoid arthritis and immunological cancers such as lymphoma. In rheumatoid arthritis CD48 along with CD244 modulates immune responses which can exacerbate inflammation. In lymphoma abnormal CD48 expression can contribute to tumor progression and immune evasion indicating its potential as a therapeutic target.

Target data

Glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein that interacts via its N-terminal immunoglobulin domain with cell surface receptors including CD244/2B4 or CD2 to regulate immune cell function and activation (PubMed : 12007789, PubMed : 19494291, PubMed : 27249817, PubMed : 9841922). Participates in T-cell signaling transduction by associating with CD2 and efficiently bringing the Src family protein kinase LCK and LAT to the TCR/CD3 complex (PubMed : 19494291). In turn, promotes LCK phosphorylation and subsequent activation (PubMed : 12007789). Induces the phosphorylation of the cytoplasmic immunoreceptortyrosine switch motifs (ITSMs) of CD244 initiating a series of signaling events that leads to the generation of the immunological synapse and the directed release of cytolytic granules containing perforin and granzymes by T-lymphocytes and NK-cells (PubMed : 27249817).
