SLAM family member 6 (SLAMF6) is a single-pass transmembrane glycoprotein encoded by the SLAMF6 gene, featuring two extracellular immunoglobulin domains, a transmembrane helix and cytoplasmic immunoreceptor tyrosine-based switch motif tail, functioning as homotypic recognition subunit of SLAM lymphocyte receptor complexes. SLAMF6 is broadly expressed across T lymphocytes, B lymphocytes and myeloid immune cell subsets, acting as central scaffold to drive homotypic cell adhesion and recruit downstream adaptive immune kinases upon intercellular receptor matching.
SLAMF6 executes biological functions via homotypic trans-assembly between adjacent immune cell surfaces, a mechanism stabilizing intercellular immune synapses and tuning intracellular adaptive immune cascade efficiency. Distinct from ligand-specific immune receptors, SLAMF6 cannot trigger full immune signals without matching homotypic counterparts and depends on intercellular dimerization for complete signal output; it recruits cytoplasmic signal mediators to synaptic receptor assemblies, separating intercellular recognition events from nuclear immune transcription factor activation and sustaining long-term adaptive immune responses. This dual regulatory mode modulates the magnitude of lymphocyte cross-talk after intercellular contact, fine-tunes lymphocyte proliferation and immune mediator secretion levels, while persistent aberrant SLAMF6 signal transmission induces overactive autoreactive lymphocyte lesions. SLAMF6 participates in core physiological and pathological events covering adaptive immune synapse formation, lymphocyte co-stimulation, autoreactive cell expansion and chronic autoimmune disorders. Abnormal SLAMF6 expression or homotypic binding capacity correlates strongly with disrupted immune self-tolerance and aggravated autoimmune tissue damage, making SLAMF6 a vital research target for SLAM receptor signaling, adaptive immunity and autoimmune disease exploration.

Beyond catalog products, Creative Biolabs offers specialized custom services for SLAMF6 research:
SLAMF6 is a homotypic SLAM receptor forming trans-cellular dimers to regulate T-B lymphocyte co-stimulatory signal intensity, maintain lymphoid immune self-tolerance and control autoreactive lymphocyte expansion upon intercellular immune contact.
SLAMF6 acts as a core controller of immune synapse assembly and adaptive self-tolerance; its dysregulation triggers autoreactive lymphoproliferative lesions, making it an essential research object for SLAM signaling and autoimmune diseases.
No, all SLAMF6 products and related services are solely intended for laboratory research, not applicable to clinical diagnosis or therapeutic administration.
The portfolio includes full-length and truncated extracellular SLAMF6 proteins, specific recombinant antibodies, and custom stable lymphoid cell lines supporting SLAM synapse and autoimmune research.
SLAMF6 proteins are tested via homotypic intercellular binding assays and co-stimulatory signal functional verification to retain native regulatory function in lymphocyte research.
