Protein
Translocation protein SEC66
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Acts as component of the Sec62/63 complex which is involved in SRP-independent post-translational translocation across the endoplasmic reticulum (ER) and functions together with the Sec61 complex and KAR2 in a channel-forming translocon complex. A cycle of assembly and disassembly of Sec62/63 complex from SEC61 may govern the activity of the translocon. SEC66 is required to attach or retain SEC72 in the SEC63 complex. It is essential for growth at elevated temperatures.
Similarity
To S.pombe SpBC409.21.
