    basic FUNCTION
  • involved in cell adhesion
  • is likely a signaling attenuator whose expression alone, i.e. in the absence of ligand engagement, is sufficient to restrain signaling in T cells
  • modulator of cellular responses and implicated in several autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and psoriasis
  • role of CD6 in autoimmunity
  • lymphocyte surface receptor putatively involved in T cell development and activation
  • modulates the threshold for thymocyte selection and the generation and/or function of several peripheral T cell subpopulations, including T reg cells

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • direct interaction between LCP2 and CD6 was shown by binding both to a phosphorylated peptide
  • contribute to DC-T-cell adhesion, stabilize DC-T-cell contacts and form a mechanical link between CD6 and the actin cortex to strengthen cell adhesion at the immunological synapse
  • upon T cell activation, SRSF1 becomes limiting, and its function in CD6 exon 5 splicing is countered by an increase in CD6 transcription, dependent on chromatin acetylation
  • interaction of LGALS1 and LGALS3 with CD6 and CD166/ALCAM might modulate some relevant aspects of T cell physiology
  • interaction between CD6 and ALCAM regulating T-cell activation
  • facilitates adhesion between T cells and antigen-presenting cells through its interaction with ALCAM, and physically associates with the T cell receptor (TCR) at the center of the immunological synapse
  • novel interactions between the SH2D2A SH2 domain and CD6 phosphotyrosine (pTyr)629 and linker of activated T cells (LAT) pTyr171 , pTyr191 and pTyr226
