Title | Gaf-1b is an alternative splice variant of Gaf-1/Rip11. |
Journal | Biochem Biophys Res Commun |
Abstract |
Gaf-1/Rip11 encoded by the clone KIAA0857 participates in endosomal recycling through the interaction with both gamma-SNAP, a member of the soluble NSF attachment protein family, and a small GTPase, Rab11. Gaf-1/Rip11 and other Rab11-interacting proteins constitute a novel protein family that is involved in the endocytic pathways. Here we report the presence of an alternative splice variant of Gaf-1/Rip11 named Gaf-1b. Gaf-1b also interacts with gamma-SNAP and is expressed ubiquitously in tissues except for liver. Subcellular fractionation analysis revealed that Gaf-1b, as well as Gaf-1/Rip11, is mainly present in the microsomal fraction. Overexpression of Gaf-1b, like that of Gaf-1/Rip11, affected the morphology of recycling endosomes. These results suggest that Gaf-1b has a similar function to Gaf-1/Rip11. |
