PROSITE documentation PDOC51386RINT1/TIP20 domain profile
Description
The following proteins playing a role in anterograde transport from the endoplasmic reticulum (ER) to the Golgi and/or retrograde transport from the Golgi to the ER share sequence similarity:
- Mammalian RINT1 (Rad50-interacting protein 1), which was originally discovered as a checkpoint protein that interacts with Rad50 only during late S and G2/M phases. RINT1 also functions in membrane trafficking from the endoplasmic reticulum (ER) to the Golgi complex in interphase cells [1,2,3].
- Yeast TIP20, which has been reported to be involved in the retrograde transport from the Golgi to the ER [4].
- Arabidopsis thaliana MAIGO2 (MAG2), functions in the transport of storage protein precursors between the ER and Golgi complex in plants [5].
They share a similar domain organization with an N-terminal leucine heptad repeat rich coiled coil and an ~500-residue C-terminal RINT1/TIP20 domain, which might be a protein-protein interaction module necessary for the formation of functional complexes.
The profile we developed covers the entire RINT1/TIP20 domain.
