Figure 4. Comparison between the inositol phoshate binding sites in the (a) Btk PH domain and (b) in the PLC-d PH domain [31]. Only the residues that are most important for the interaction are indicated and coloured red and orange. K12 and R28 in Btk superimpose with K30 and R40 in PLC-d. The Ins(1,3,4,5)P[4] in Btk and the Ins(1,4,5)P[3]in PLC-d are in cyan.
