RAB4B — RAB4B, member RAS oncogene family
RAB4B belongs to a gene co-expression module in 1 of 28 SCUBA cell types. Each module groups genes that rise and fall together in that cell type; the genes it shares a module with are its closest co-expression partners there.

Function
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 (By similarity). RAB4B mediates endosomal tethering and fusion through the interaction with RUFY1 and RAB14. Acts as a regulator of platelet alpha-granule release during activation and aggregation of platelets (By similarity).
