GTP-binding protein that possesses intrinsic GTPase activity. Contributes to the polarizing activity of KRIT1 and CDH5 in the establishment and maintenance of correct endothelial cell polarity and vascular lumen. Required for the localization of phosphorylated PRKCZ, PARD3 and TIAM1 to the cell junction. Plays a role in the establishment of basal endothelial barrier function.

Talin-F0 domain binds to Rap1b like canonical Rap1 effectors despite little sequence homology, and disruption of the binding strongly impairs integrin activation, cell adhesion, and cell spreading. PMID: 29170462
Aberrant expression of lncRNA AFAP1-AS, a competing endogenous RNA of miR-181a, may involve in the onset and progression of Hirschsprung disease by augmenting the miR-181a target gene, RAP1B. PMID: 28924375
In RCC tissues and renal carcinoma cells, miR-28-5p is expressed at a low level and RAP1B is expressed at a high level. miR-28-5p inhibits the tumorigenesis of RCC by directly downregulating RAP1B and influencing the activation of two MAP kinases in the MAPK signaling pathway, p38 and Erk1/2.
