Functional narrative |
The gamma subunit of Sec61, a member of the SecE/Sec61gamma family, is an essential member of a complex which assists in the translocation of proteins in the endoplasmic reticulum. Sec61gamma is bound by its tail to the membrane of the cell. It interacts directly with Sec61-alpha and Sec61-beta and also indirectly with many other secretory proteins. This protein was characterized via the analysis of a synthesized fragment containing amino acid residues 1 - 43. A point mutation, Cys24Ser, was also included in the synthesis of this fragment. The mutation was introduced in order to prevent dimerization. The disordered regions in Sec61 gamma are associated with membrane binding.
