Inactivation of signaling protein
WebOct 30, 2006 · The active receptor triggers the activation of the G protein by exchanging the GDP with a GTP. The G protein dissociates into its subunits, which transmit the signal downstream by binding to other proteins and activating or inhibiting biochemical processes. The α-subunit carries the GTP. WebWe used reverse-phase protein microarrays (RPMA) to measure total and phosphorylated HER2 in the context of HER family signaling to understand correlations between phosphorylated and total levels of HER2 and downstream signaling activity.Experimental designThree independent study sets, comprising a total of 415 individual patient samples …
