Mincle receptor

Macrophage inducible Ca2+-dependent lectin receptor, (abbreviated to Mincle), is a member of the C-type lectin superfamily encoded by the gene CLEC4E. It is a pattern recognition receptor that can recognize glycolipids including mycobacterial cord factor, trehalose-6,6'-dimycolate (TDM). The mincle receptor binds a range of carbohydrate structures, predominantly containing glucose or mannose, and play an important role in recognition of bacterial glycolipids by the immune system. Upon activation by cord factor, Mincle binds the Fc receptor FcRγ and Syk. Cord factor also binds and activates the related C-type lectin MCL. Upon receptor stimulation is PKC-δ activated, which subsequently phosphorylates CARD9 that triggers recruitment of BCL10 and MALT1, leading to a CARD-CC/BCL10/MALT1 (CBM) signaling complex. This signaling complex in turn triggers downstream recruitment of TRAF6 and NF-κB activation.
