TMEM163 interacts with dysbindin. (A) Co-IP of endogenous platelet proteins show that dysbindin precipitates TMEM163. (B) Co-IP of endogenous platelet proteins show that TMEM163 precipitated dysbindin. The immunoglobulin G (IgG) was used as a negative control. (C) Co-IP of endogenous platelet proteins show that dysbindin precipitated TMEM163 in sdy^+/− platelets, but not in sdy platelets. (D) Co-IP of endogenous platelet proteins show that TMEM163 precipitated dysbindin in WT (B6, C57BL/6J) platelets, but not in Tmem163-KO platelets. All the inputs corresponded to 8% of whole platelet lysates.
