>cd04148 RGK RGK subfamily. The RGK (Rem, Rem2, Rad, Gem/Kir) subfamily of Ras GTPases are expressed in a tissue-specific manner and are dynamically regulated by transcriptional and posttranscriptional mechanisms in response to environmental cues. RGK proteins bind to the beta subunit of L-type calcium channels, causing functional down-regulation of these voltage-dependent calcium channels, and either termination of calcium-dependent secretion or modulation of electrical conduction and contractile function. Inhibition of L-type calcium channels by Rem2 may provide a mechanism for modulating calcium-triggered exocytosis in hormone-secreting cells, and has been proposed to influence the secretion of insulin in pancreatic beta cells. RGK proteins also interact with and inhibit the Rho/Rho kinase pathway to modulate remodeling of the cytoskeleton. Two characteristics of RGK proteins cited in the literature are N-terminal and C-terminal extensions beyond the GTPase domain typical of Ra
