Ras related protein rab 1c (GTP binding protein ray)
Ras related protein Rab35
Ras-related protein Rab-1C
Ras-related protein Rab-35
FunctionIn the process of endocytosis, essential rate-limiting regulator of a fast recycling pathway back to the plasma membrane. During cytokinesis, required for the postfurrowing terminal steps, namely for intercellular bridge stability and abscission, possibly by controlling phosphatidylinositol 4,5-bis phosphate (PIP2) and SEPT2 localization at the intercellular bridge.
Sequence similaritiesBelongs to the small GTPase superfamily. Rab family.
Cellular localizationCell membrane. Membrane > clathrin-coated pit. Cytoplasmic vesicle > clathrin-coated vesicle. Endosome. Melanosome. Present on sorting endosomes and endosomal tubules. Tends to be enriched in PIP2-positive cell membrane domains. During mitosis, associated with the plasma membrane and present at the ingressing furrow during early cytokinesis as well as at the intercellular bridge later during cytokinesis. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
