"[In this paper, we report that the PH domain of Btk functions as an inositol 1,3,4,5-tetrakisphosphate (IP4), inositol 1,3,4,5,6-pentakisphosphate, and inositol 1,2,3,4,5,6-hexakisphosphate (IP6) binding domain (Kd of approximately 40 nM for IP4), and that all of the XLA (Phe replaced by Ser at position 25 (F25S), R28H, T33P, V64F, and V113D) and Xid mutations (R28C) found in the PH domain result in a dramatic reduction of IP4 binding activity.].
