Previous GeneCards Identifiers for RAB21 Gene
This gene belongs to the Rab family of monomeric GTPases, which are involved in the control of cellular membrane traffic. The encoded protein plays a role in the targeted trafficking of integrins via its association with integrin alpha tails. As a consequence, the encoded protein is involved in the regulation of cell adhesion and migration. Expression of this gene is associated with a poor prognosis for glioma patients. This gene is downregulated by the tumor suppressor miR-200b, and miRNA-200b is itself downregulated in glioma tissues. [provided by RefSeq, Nov 2015]
GeneCards Summary for RAB21 Gene
RAB21 (RAB21, Member RAS Oncogene Family) is a Protein Coding gene. Among its related pathways are RAB geranylgeranylation and Sertoli-Sertoli Cell Junction Dynamics. GO annotations related to this gene include GTP binding and GDP binding. An important paralog of this gene is RAB5C.
UniProtKB/Swiss-Prot for RAB21 Gene
Regulates integrin internalization and recycling, but does not influence the traffic of endosomally translocated receptors in general. As a result, may regulate cell adhesion and migration (By similarity). During the mitosis of adherent cells, controls the endosomal trafficking of integrins which is required for the successful completion of cytokinesis. Involved in neurite growth (By similarity).
