Figure 3. CD33 ITIM and ITIM-like Sequences Aligned to Consensus ITIM sequence.
The CD33 ITIM and ITIM-like sequences (underlined) are shown relative to the ITIM consensus sequence of S/L/V/IxYxxL/V/I. Note that the CD33 ITIM-like sequence begins with a threonine, as opposed to the consequence S/L/V/I, and hence is relatively well-conserved with the consensus. The spacer between the ITIM and ITIM-like sequence in CD33 is 12 amino acids.
