|Previously, the ILT family was clustered together as CD85. Recently subclassifications have been given to individual members listed as CD85a - CD85m. Ig-like transcripts (ITLs) and leukocyte Ig-like transcripts (LIRs) are structurally and functionally related transmembrane glycoproteins. The receptors are divided into 2 groups of inhibitory and activating receptors according to the nature of their transmembrane and cytoplasmic regions. Receptors with a long cytoplasmic tail, CD85a (ILT5/LIR3), CD85c (LIR8), CD85d (ILT4/LIR2), CD85j (ILT2/LIR1) and CD85k (ILT3/LIR5), contain one or more intracytoplasmic ITIMs which recruit and activate protein tyrosine phosphates SHP-1 and/or SHP-2. Receptors with a short tail, CD85b (ILT8), CD85f (ILT11), CD85g (ILT7), CD85h (ILT1/LIR7) and CD85i (LIR6a) lack ITIMs and contain a positively charged aa residue, arginine or lysine, in their transmembrane domain which is necessary for association with ITIM-containing polypeptides like FcRg chain. CD85l (ILT9) and CD85m (ILT10) bind the FcRg chain. Phosphorylated ITAMs recruit the protein tyrosine kinases Syk and ZAP70. One exception to these transmembrane receptors is CD85e (ILT6/LIR4) which has no transmembrane or cytoplasmic domains and is probably soluble. |
