Comments concerning this interaction

Source was fixed larval body wall of wild-type fly line; proteins produced from endogenous genes.

hts also binds phosphoinositides via it\'s MARCKS domain (GSPKKDKKKKKGLRTPSFLKKKKEKKKAEA).

The hts antibody used recognizes the C-terminal MARCKS domain. The dlg1 antibody used recognizes the N-terminal PDZ domain. The PLA signal develops only if both primary antibodies are in close proximity to each other (within tens of nanometers).
