The translocon-associated protein (TRAP, also known as the signal sequence receptor) complex is required for the efficient translocation of secretory and membrane proteins in the endoplasmic reticulum, and is also involved in the endoplasmic reticulum stress-mediated unfolded protein response pathway. This entry represents the gamma subunit of the translocon-associated proteins. Trap-gamma (also known as SSR3) appears to be required for vascular network formation in murine placental development [].
