Hemitam
HemITAM receptors are C-type lectin-like receptors (CTLRs) that are encoded by genes clustered together in the natural killer gene complex (NKC), which includes the Dectin-1 cluster and members of the NKRP1 receptor family. The expression profile for each receptor is indicated for both mice (m) and humans (h). WebThe hemITAM segment consists of the tyrosine phosphorylation motif YXXL adjacent to an upstream triple of acidic amino acids (Hughes et al., 2013). Phosphorylation of the hemITAM YXXL is catalyzed ...
