SYS1

SYS1
PFAM accession number:PF09801
Interpro abstract (IPR019185):

Members of this family are integral membrane proteins involved in protein trafficking between the late Golgi and endosome. They may also serve as a receptor for ADP-ribosylation factor-related protein 1 (ARFRP1) [ (PUBMED:15203023) ]. Sys1p is a small integral membrane protein with four predicted transmembrane domains that localises to the Trans Golgi network TGN in yeast and human cells [ (PUBMED:16926193) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry SYS1
