Text-mined interactions from Literome

Chakrabarti et al., Mol Cell Biol 2005 : Furthermore, elevated Kalirin expression resulted in catalytic activation of TrkA, as demonstrated by in vitro kinase assays and increased NGF stimulated cellular activation of Rac , Mek, and CREB
Koo et al., BMC cell biology 2007 : Kalirin5 induced Rac1 activation is increased by the expression of wild type Arf6 and decreased by Arf6T27N
Impey et al., Mol Cell Neurosci 2010 : Additionally, we show that the miR132/p250GAP circuit regulates Rac1 activity and spine formation by modulating synapse-specific Kalirin7-Rac1 signaling
