RAB1B

Members of the RAB protein family, such as RAB1B, are low molecular mass monomeric GTPases localized on the cytoplasmic surfaces of distinct membrane-bound organelles. RAB1B functions in the early secretory pathway and is essential for vesicle transport between the endoplasmic reticulum (ER) and Golgi (Chen et al., 1997 ; Alvarez et al., 2003 ).

Interaction

Interacts with MICAL1 and MICAL2 (PubMed:15694364, PubMed:27552051). Interacts (in GTP-bound form) with MICALCL, MICAL1 and MILCAL3 (PubMed:15694364, PubMed:27552051). Interacts with GDI1; the interaction requires the GDP-bound state (PubMed:8836150, PubMed:11389151). Interacts with CHM/REP1; the interaction requires the GDP-bound form and is necessary for prenylation by GGTase II (PubMed:9437002, PubMed:11389151). Interacts with RabGAP TBC1D20 (PubMed:23236136). Interacts (in GDP-bound form) with lipid phosphatase MTMR6 (via GRAM domain); the interaction regulates MTMR6 recruitment to the endoplasmic reticulum-Golgi intermediate compartment (PubMed:23188820). Interacts (in GDP-bound form) with lipid phosphatase MTMR7 (By similarity). (Microbial infection) Interacts with L. pneumophila AnkX (PubMed:21822290, PubMed:22307087). Interacts with L. pneumophila Lem3 (PubMed:22158903, PubMed:22307087). Interacts with L. pneumophila SidD (PubMed:21734656, PubMed:21680813). Interacts with L. pneumophila DrrA (PubMed:20064470, PubMed:20651120).
