Previous GeneCards Identifiers for RAB1B Gene
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 [PubMed 9030196]; Alvarez et al., 2003 [PubMed 12802079]).[supplied by OMIM, Jan 2009]
GeneCards Summary for RAB1B Gene
RAB1B (RAB1B, Member RAS Oncogene Family) is a Protein Coding gene. Diseases associated with RAB1B include legionaire disease. Among its related pathways are Cell Cycle, Mitotic and Transport to the Golgi and subsequent modification. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is RAB37.
UniProtKB/Swiss-Prot for RAB1B Gene
The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. RAB1B regulates vesicular transport between the endoplasmic reticulum and successive Golgi compartments. Plays a role in the initial events of the autophagic vacuole development which take place at specialized regions of the endoplasmic reticulum.
