We previously reported that diacylglycerol (DG) kinase (DGK) δ interacts with DG‐generating sphingomyelin synthase (SMS)‐related protein (SMSr), but not SMS1 or SMS2, via their sterile α motif domains (SAMDs). However, it remains unclear whether other DGK isozymes interact with SMSs. Here, we found that DGKζ, which does not contain SAMD, interacts with SMSr and SMS1, but not SMS2. Deletion mutant analyses demonstrated that SAMD in the N‐terminal cytosolic region of SMSr binds to the N‐terminal half catalytic domain of DGKζ. However, the C‐terminal cytosolic region of SMS1 interacts with the catalytic domain of DGKζ. Taken together, these results indicate that DGKζ associates with SMSr and SMS1 in different manners and suggest that they compose new DG signaling pathways. [ABSTRACT FROM AUTHOR] |
