Rft-1

Rft-1
PFAM accession number:PF04506
Interpro abstract (IPR007594):

Asymmetric lipid distribution is a fundamental characteristic of biological lipid bilayers, one such axample is the translocation of the Man 5 GlcNAc 2 -PP-Dol intermediate from the cytosolic side of the ER membrane to the lumen before the completion of the biosynthesis of Glc 3 Man 9 GlcNAc 2 -PP-Dol [ (PUBMED:11807558) ]. RFT1 encodes an evolutionarily conserved protein required for this translocation.

GO process:dolichol-linked oligosaccharide biosynthetic process (GO:0006488)
GO component:integral component of membrane (GO:0016021)
