... receptor, as well as to induce intracellular force sensing. The FERM domain allows the strategic positioning of protein–protein and protein–lipid interfaces, including the membrane-binding and integrin affinity-regulating F1 loop, as well as the interaction with lipid-anchored Rap1 (Rap1a and Rap1b...

...Thomas Bromberger; Liang Zhu; Sarah Klapproth; Jun Qin; Markus Moser ABSTRACT Recruitment and tethering of talin to the plasma membrane initiate the process of integrin activation. Multiple factors including the Rap1 proteins, RIAM (also known as APBB1IP) and PIP 2 bind talin proteins and have been...

A mutation that blocks the direct binding of Talin to Rap1 abolished Talin recruitment to sites of adhesion and the resulting phenotype phenocopies that seen with null...

... prolonged agonist treatment; however, the underlying mechanisms are unclear. Here, we identify the small GTPase Rap1 as a key regulator for promoting GABA B receptor surface expression. Agonist stimulation of GABA B receptor signals through Gαi/o to inhibit Rap1GAPII (also known as Rap1GAP1b, an isoform...

At somatic mammalian telomeres, the NHEJ factor Ku70/80 inhibits HR, as does the Rap1 component of the shelterin complex. Here, we investigated the role of Ku70 and Rap1 in meiotic telomere redistribution and genome...

...-signal transduction, we performed a small-scale siRNA screen in A549 lung epithelial cells. Of the Rap effectors tested, only Radil blocked Rap-induced spreading. Additionally, we identified a novel role for Ezrin downstream of Rap1. Ezrin was necessary for Rap-induced cell spreading, but not Rap-induced...

We show that Rap1 activity is regulated during this process. Changes in Rap1 activity play an essential role...

...Matthijs R. H. Kooistra; Nadia Dubé; Johannes L. Bos Rap1 is a Ras-like small GTPase that is activated by many extracellular stimuli and strongly implicated in the control of integrin-mediated cell adhesion. Recent evidence indicates that Rap1 also plays a key role in formation of cadherin-based...

The activation of Rap1 by both cAMP and NGF was blocked by PP2, an inhibitor of Src family kinases, and by a Src mutant incapable of being...

Whereas its early history has focused on its biochemical homology to Ras and the alleged functional antagonism between these two small GTPases, recent cellular evidence suggests that endogenous Rap1 plays a unique, Ras...
