SAMPpfam05924SAMP Motif. This short region is found repeated in the mid region of the adenomatous polyposis proteins (APCs). This motif binds axin.
PDE6_gammapfam04868Retinal cGMP phosphodiesterase, gamma subunit. Retinal rod and cone cGMP phosphodiesterases function as the effector enzymes in the vertebrate visual transduction cascade. This family represents the inhibitory gamma subunit, which is also expressed outside retinal tissues and has been shown to interact with the G-protein-coupled receptor kinase 2 signalling system to regulate the epidermal growth factor- and thrombin-dependent stimulation of p42/p44 mitogen-activated protein kinase in human embryonic kidney 293 cells.
G-alphacd00066Alpha subunit of G proteins (guanine nucleotide binding). The alpha subunit of G proteins contains the guanine nucleotide binding site. The heterotrimeric GNP-binding proteins are signal transducers that communicate signals from many hormones, neurotransmitters, chemokines, and autocrine and paracrine factors. Extracellular signals are received by receptors, which activate the G proteins, which in turn route the signals to several distinct intracellular signaling pathways. The alpha subunit of G proteins is a weak GTPase. In the resting state, heterotrimeric G proteins are associated at the cytosolic face of the plasma membrane and the alpha subunit binds to GDP. Upon activation by a receptor GDP is replaced with GTP, and the G-alpha/GTP complex dissociates from the beta and gamma subunits. This results in activation of downstream signaling pathways, such as cAMP synthesis by adenylyl cyclase, which is terminated when GTP is hydrolized and the heterotrimers reconstitute.
